I've got tears from laughing,you're going through every bit of nonsense I deal with at work.You just took a migraine of diagnostic nonsense and made it clear and easy.Damn it I hate when I see a hole in wire insulation,almost always green.

I have been a repairman since 1973. I taught HVAC for the local apprenticeship program for about 10 years. Dan is a great instructor and a decorated repair technician. Thanks Dan for making our job a lot easier!

Load pro is an awesome product and the Voltmeter only method of diagnostics works. I am a professional Transit Bus Tech with 17 years of experience and electrical and electronic diagnostics is one area I do quite a bit of work in. I'm Master Ase Certified Transit Tech with L2 certification also. I have been using Dan's tool since 2009 and it hasn't failed me. If you use Dan's tool and method you will without a doubt a more competent and efficient electrical tech.

Dan, I bought one of your LodaPros and I absolutely love it. I have been a Technician for 38 years and I think what you are doing is great. You taught this old dog a new way of electrical diagnosis and I'm a better diagnostician for it.

I have bought your product with the text book and it changed my career. Thank you. I understand your way of explaining better then others and I have successfully diagnosed using your methods. Now mine. Very grateful Mr Sullivan.

Dan, thanks to your invention and your books and training, diagnosing electrical faults is just as easy as fixing a flat tire!

Hey Dan, I've been using the loadpro (in blue point blue) for about two years. Your tool and training videos has saved me countless hours in diag time. I tell everyone I know that runs a multimeter that they should invest in a loadpro and watch your videos. Thanks for your passion and dedication.

Keep up the good work Sir! I found these 6 years old videos and they are Gold. Thank you for loading these videos.

Dan, you are a very good teacher. I first saw the Loadpro mentioned a few days ago and couldn't understand what it is. You are a genius to have thought of this method and then created a simple to use tool to encompass the method. Of course the inventor never is rewarded. Stay with your attitude toward the haters. They ain' nothin.

Excellent video and understanding of the circuit. Really Electrical problems are simple in nature if one knows electrical and know how to troubleshoot electrical circuit. Otherwise without following rules and understanding it is a big pain. Regards,

Dan, This video/presentation is almost 8 years old and IS the BEST by far!!!!! I am 54 years old and I have been a Ford Dealership Technician since 1987. I achieved Ford Senior Master status in 1999, with my specialty being in drivability, electrical and vehicle electronics. That all stated, you TOTALLY NAILED every point!!!!! From the beginning, describing just how Service Managers act regarding electrical/electronic diagnostics......to the manual fiasco.......to circuit diag. SPOT ON my friend!! SPOT ON!!!! I literally just ordered a "LOADPro" from Electronic Specialties (Model 180) for use with my Fluke 88. You did a WONDERFUL thing by developing and creating this EXCELLENT tool. Guys make electrical/electronics diagnosis WAY TOO difficult. It is not "magic", it IS knowing how to read and interpret schematics, and knowing the system you are diagnosing. Thank you for your work! Patrick P.S. BTW, I also own the ESI "Low Current Probe" (687) ans the ESI "Relay Buddy Pro" (191). ESI offers a LOT of excellent diag tools! Thank YOU Dan!

Thanks Mr.Dan can't wait to get my loadpro today! I work for Penske truck leasing . I truly believe the loadpro is going to make me a better diagnosistiction! I've seen most of your videos.

I was going to buy a Power Probe Hook until I accidently came across your KZread videos. After watching almost all of your videos over the last three hours I just purchased your LoadPro 181. You have solid teaching videos! I'm looking forward to using your product!

This month's issue of Professional Tool & Equipment News has a positive endorsement of Load Pro in the Top 10 Tools article . I have two sets and love them .

Hello Daniel, I have been working on cars for 25+ years and consider myself good at electrical diagnosis. I ran across your video and was blown away! It is so simple to understand and should quicken my all ready quick diag! I ordered your tool and cannot wait to start using it! Thank you for creating something that can shorten the 64 pages of diag in the manuals!!!!!!!!!!!! Great job!

Hi Daniel, thank you for your invention and LOADpro sits in my diagnosis box all the time. LOADpro saves me time and above all gives me confident peace of mind in my diagnosis works. You got your fan in Korea.

@bivideo7 With my heart, thank you and your father's sacrifice. I served in the 18th Medcom, 8th US Army in Korea. I trust with active marketing of LOADpro in Korea, more automotive shops will enjoy the LOADpro benefits.

Sir I recently stumbled upon you videos and decided to order your tool. Since then you have made me money and I am deeply thankful! Keep up the good work.

I couldn’t figure out what I needed. This or a “power probe”. Honestly I was more skeptical of this tool than the load pro. Mainly because I have never understood circuits. Well I got both and now I’m just pissed about all the complicated garbage people tried to teach me about troubleshooting a DC circuit problem over the past 20 years (I’m 38) After using both tools, the load pro is so easy and really all you need. Sullivan is awesome. He’s like Eugene Stoner whoe designed and built the longest serving US service rifle- a shop guy who is smarter than all the school trained engineers. And we should all be pissed about how corporations and their attorneys screw the real Americans over in this country. As a modern day farmer where circuits are my biggest headache, this load pro and Dan’s videos are a game changer. I’m waiting get his book but should be here this week. Thanks Dan

After watching this video I realize that I do not ask "What is wrong with it?" when inquiring about a vehicle my apprentice mechanics are working on. I ask "What is is doing or not doing?" They may not know what is wrong with it but may be able to tell you what it is doing or not doing that is abnormal for it. Then I will have a better understanding of what the problem may be and lead them in the right direction if I have experienced that problem in the past. BTW, I have the LOADpro and I would recommend the book (Fundamental Electrical Troubleshooting) with it. The book will show you test and different scenarios in a simple to understand format. Thank You, Dan.

Dan, I purchased your book and LOADpro tool several months ago. I wish I had you for an instructor years ago when I was in maintenance school. I learned more from your book and videos than I have anywhere else.Wiring makes so much more sense and is easier to apply the knowledge the way you teach it. I don't dread the electrical problems like I did before. Thank you for all the work.

I would just like to take a moment and thank you for making the loadpro, I bought it to find a fault on a 2001 skoda. The ac clutch had system voltage until loaded, loaded it dropped and it was the positive side the problem was on, turned out to be a corroded fuse. Thank god I had the loadpro to help me on the way :)

95tt Well, heck. Glad to know it worked that well. I get that story a lot and it's this kind of message that keeps me going. Just curious -- do you recall the reaction you had when you saw the voltage drop? I mean - you saw 12V, you pushed the button, the voltage dropped, and your reaction was???

Dan thanks, great revision of an old video. Your invention ROCKS. I encourage every new tech to get one and hone their electrical diagnostic skills, because every system on a modern vehicle has some form of electrical circuit associated with it. I'll admit I am old school and know that a good understanding of Ohms Law and how to perform voltage drops on a live circuit are all you need to find your problem. I have done it and know it works when performed correctly. Unfortunately not too many techs use the voltage drop method or know how. I own a test light/voltmeter and it has served me well. Now you tested the positive side of the fan motor with a test light/voltmeter and read source voltage because the circuit was not complete. Plug the fan motor in and test it again and you will see a different result. Ha ha you know that. Next place your test light / voltmeter from the fuse to the fan motor and that would give you the voltage drop indicating a problem. Ha ha you know that too. Now you would have spent a whole lot of time performing voltage drops at various locations on the circuit removing who knows what. Yes you said that as well. Now you did mention that using the test light/voltmeter in an UNLOADED circuit is useless. On that we are in sync. We are also in sync in that your invention simply put is a no brainier. Not much thought, Not much time wasted and No scratching your head thinking did you {mis} something. Ha ha. I am proud to say that I own a LOAD PRO. Now I did say I am old school and break out my test light/voltmeter ( creature of habit ) or Alzheimer's but windup putting it back for the LOAD PRO. Now the true difference between a test light/voltmeter and the LOAD PRO is that an UNINFORMED tech/person can use a LOAD PRO with a higher degree of accuracy and efficiency. Which by the way may have others thinking your competent. I like my test light/voltmeter but it to will pass like the dinosaurs once the LOAD PRO takes off. Again many thanks for your invention and sorry if I ran on and on but I had nothing else to do all my work is done. Damm LOAD PRO:).

Excellent product, excellent book! I've been in the motor trade here in the UK for 20+ years now and this is one of the best things I've ever bought. I can't recommend it enough! (the steadypins are a sanity saver!)

hi dan, i bought your book F.E.T and loadpro. i bought your book E.P.G. i have employed your volts only diagnostics method and can honestly tell you your methods and teaching are brilliant. the volts only diagnostic testing is the way forward . so a MASSIVE thank you to you dan. keep up the good work

Dude, Dan......I can not stress how much this and your other videos helped. I have been trying to figure out electrical troubleshooting for some time now. i am understanding more and more through practice on my 92 roadmaster. but dude, I came leaps and bounds watching some of your videos. you speak in the language that I get. you simplify it so the facts are understandable. sheesh!

Outstanding, I plan on purchasing this tomorrow, I totally agree Dan awesome job! And I have learned lots!

What's right..is correct! Your understanding,experience and method is the best on youtube!

Thanks Dan for a no nonsense approach….. Love the Vid and Tool!!

You're a good man, Dan Sullivan. I've seldom seen videos that talk this much sense. My Load Pro has never let me down. I understand the principle, no bull***t - job done. Why complicate things? But you've got the impossible task of convincing the rest of the world. Best wishes from London

Dan you are spot on about this. I have worked many years for many Electrical contractors and they are all about the same, they want and expect too much out of their workers, ( I have a lot of stories) Great videos, subbed.

I have been doing mechanical work all my life. I was always somewhat intimated by electrical problems. When my son began taking classes I forced myself to Learn to read diagrams and electrical theory and cannot tell you what a huge difference it has made. Simply knowing the way things work makes the job so much easier.

Thank you for your time and experience. You are the best .!!

There’s quite a bit of psychology amongst this. Love it! Thanks 😊

I'm a very hard learner and had lots of trouble in my school years. Im 29 now and I've just recently say in the last year really gained the confidence to expand my brain with knowledge instead up putting up barriers within myself and say things like, "I hate electrical, im horrible at it i'd rather pay then do it myself its confuses me too much" I've also had a pretty life changing year for myself to give myself the oppertunity to teach myself through youtube doing my own projects while watching. Tho I understand the use of the powerprobe better, I understand you and learn from what you say. I just ordered my power probe and have no experience before hand with one. I think these are completly different tools but can be related like a 2nd cousin. They both are great products from what i have heard. Thank you for your contributions to the industry sir! =)

Incredible explanation. You are absolutely a consummate professional.

Dan ur awesome. I’m 9 years late finding u on here but I love your product and ur philosophies. Thanks man

hello Dan ! I just bought the loadpro 180 it feels very well made & i'm looking forward to use it soon & hope you can renew your patent !! & i enjoyed you videos! thank you!!

Dan, just received your Electrical Training Cards today. I'm excited to get goin on them. I will report back on how it goes. Thank you again for doing what you do.

Best tool and best video ever thank you. I can’t even tell you how much time this tool has takin off jobs of mine. your tool has saved me thank you

As a retired nuclear submarine mechanic on nonnuclear equipment, I know were you’re coming from. I invent all kinds of tools to help me get the job/task done. Would you believe after creating a tool that changed the task from 8hrs to 30mins was frowned upon by other workers because it meant they had to go somewhere else to work on i.e. “milking another job”! Understanding how everything is integrated is paramount! When an entire naval shipyard couldn’t figure out what was the problem, I crawled all over looking for the problem while it was being operated & in less than one hour found the culprit which needed repairing. Many submarines weren’t going anywhere until I diagnosed the situation and told them what to do or fixed it myself. I could go on and on with many more situations in which people weren’t telling/giving all the facts that was needed to figure out the discrepancy.

Dan, i teach at a tech College and love the Load Pro. Great tool. Keep up the good work!

Hi Dan, thank you for your video about LOADPRO. I would admit that (indeed) LOADPRO is such a simple yet powerfull tool in finding electrical problem. I had shown the trick with my colleague, at first he misdiagnosed the trouble thinking it was the component that is malfunctioning but when I used the loadpro, he was like....what the ####? thats cool tool bro, he told me. Thank you for sharing your knowledge, I appreciate it a lot and btw I am a teacher also like you.

Just discovered your videos. You think like I do. I think I'll be ordering your tool. Thanks. People complicate electrical problems all the time.

I work on everything all brands of cars and this tool is heaven sent that is why i bought it two years ago still works great love this tool makes everything so much simpler . I am going to try this for voltage drop testing with an oscilloscope an thanks for the video .

I'm gonna purchase the tool through Amazon. Hope you get the patent work you deserve the credit. Thanks I will be watching more of your videos.

Dan I knew after seeing your video that the load pro was a killer idea I'm going to buy one for myself and my father

You r very smart and knowledgeable probably scares others very clear way to explain it

This guy has it right! Hey don't worry about what the other companies are doing or trying to do. Just continue to innovate and push your product as an electrical issue solution. I'd suggest listing a link to videos on how to use your load pro as well, again working on the angle that customers can solve issues.

Continued from previous post; Now... Using the LOAD PRO is like using a calculator to solve this problem 24356 X 87234 = . Sure you can solve it with a pencil AKA test light/voltmeter and eventually get the same answer. But, the LOAD PRO will most definitely get you the answer increasing your efficiency and accuracy to the point some might label you competent. I still recommend honing your understanding of OHMS LAW and the voltage drop method just in case the LOAD PRO happens to get run over. Thanks again Mr. Sullivan for an AMAZING product Ed Q.

Great explanations here Mr. Sullivan. I wish I had seen this like forty years ago.You are an excellent teacher sir.

Thanks Daniel you make life easier

DAN! you hit the nail right on the head on the company I work for! lol 😂 they guy expects for everything to be fixed in 5 minutes! lol its so freaking unreal nothing takes five minutes in this kind of field lol I own a power prob 3 but every time I need to use it I have to hook to the battery.. I work on big heavy equipment and also your normal dump trucks and stuff This is so awesome I can just get in side with my meter and test stuff with out having to bust out the power prob for some testing .. Man I'm so glad you made this video lol gonna share it with some co workers lol .. definitely gave you a Sub keep up the good work and these dam trucks are getting to be a pain in the ass to work on I wish they would of just kept it simple !!! but nooooo need a 1000 things to make one thing work now uhhhh. 🤦🏽‍♂️ lol I'm a diesel mechanic but I've been the fall guy to do electrical because no else has the patience for it lol .. I have some experience but like you said if the company doesn't invest in the information it makes my job harder so I really have to get the wheels turning in my head lol but thank god for cell phones with internet lol once I under stand how the system works I can find the problem quite .. but like you said everything is changing so fast its just getting to be ridiculous lol .. I'm defiantly going to order your tool !! looking forward to using it!

You're the fucking man Daniel. I work at Penske truck Leasing and rental in CA and our trainers swear by your tool and wanted us to start using it. I just begin using it a few months ago and ohmygosh. Best tool I have ever used. I begin teaching it to another tech at the shop. Thanks man

You are a master!!! Excelent video!!!

I am at the point in the FET manual where the Loadpro instructions are. I haven't used the leads yet but I have learned a lot from the book. Thanks Daniel!

I work on refuse trucks for a living, and your are right on the money. The systems are getting more complicated and my Forman is constantly wanting me to put a time to the job. And sometimes it can take a hour sometimes it can take a full day depending on the manufacturers support. I’ve been using a 15 amp light in line with a multimeter and just a mess of different pines and back probes finally started using a load pro and found it to cut my dish time in half. But wish the would off one in different resistance values, I have found that it helps most of the time but sometimes it doesn’t catch the problem all the time depending on the amps of the circuit

That's a great video, I learned a lot from it.

I've never heard of this product before but I've been using a power resistor in a jumper to perform the same diag procedure and except for intermittent faults the procedure works 100%

Kudos Daniel !!! love your work mate and happy to get on board … where were you when i did my trade training 40+ years ago 👍 great going and don’t worry about the neigh sayers …their loss !

Got a load pro ordered from amazon to test old honda trikes, like mentioned in video could build one myself prolly but yours is convenient, and gotta support creators, hopefully it finds my wire issue

Still love watching all your videos

I’ve finally found a teacher that understands the subject! Thanks so much for the help. I found it at Amazon and need to know if you have a newer model coming or is the 181 the one to get

Seens every auto mag you read has voltage drop instructions, This load pro takes the hard problem and makes it so easy,, I used it on A Harley that the tail lite was not working found the problem in 5 min. it was the harness under the rear fender some time the owner must have had A Big Mommy that caused the tire to rub the harness,, Yes I love my Load Pro..,,,thanks Dan

just order my load pro.. been a power probe user for years(still keeping it) ..I work for the US BORDER PATROL and we have all the police equipment plus lots of special lighting equipment.cant wait to use it.

In my case I get these trucks after about 3 or 4 sometimes more than that other techs have already been into the truck for 20+hrs. At that point it's like, well first I have to find out what other issues were created then find the initial problem and fix that too. But I think it's important to have an idea of what you think the problem is before you start so you know where to start at. Example: truck comes in and HVAC blower motor is inop. The manual has you check a lot of other things first but from experience we know to look at the green connector on the frame mounted PDM first because the power pin here burns often. This can save you a lot of time in diag to check these known problem areas first.

I like the video and I think your idea of diagnosing is spot on. I had a professor teach me the same thing years ago and it made electrical easier to understand. I can easily see this working on two wire connections but what about 3, 4 wire connectors? So I guess my question would be is this only best for simple circuits? If not I would love to see a demonstration done on a more complex circuit

At about 13 min crucial. Great job explaining TY

Thanks Dan, Great tool. I've had mine for a year now and for some reason it stopped working. I dread going back to regular leads. Is there some place or way to repair it?

Keep up the great work

The test light is such a powerful tool because it loads the circuit with .25-.5 amps.

Mind blown. Its so simple

Dude, I fucking love this guy! I had to take a class for 2 months at LinTech to understand that all I need to look for is source voltage and loading the circuit!!!!!! SMDH

Just wondering how this tester would work for circuits that are monitored by the PCM and usually have a 5 volt signal etc. I am looking at an ambient air sensor code now and this got me to wondering if this tool would allow me to test the integrity of the wires running back to the PCM. It is running a P0073 code, which may be a break or high resistance in the wire somewheres.

Daniel its an excellent tool , it costed me more than 100 $ , mainly shipping and tax but I think money well spent.

Hey I love the Load Pro I have the original red one with the book and it has saved me tons of time over the years. Just last week it helped me diagnose a heated seat problem on a Nissan, it ended up having a huge voltage drop across the switch. I got 12 volts at the heating element until I put a load on the circuit end up with a 4 volt drop somewhere in the positive side of the circuit. Ended up being the switch. I could totally see someone ordering a new pad and removing the seat and element only to find out it still doesn't work. Great tool!!! My question is if anyone knows of an alligator clip that would fit well on the test lead. Part number and manufacturer please. Thanks again Dan for such a great tool

Does the load pro eliminate risk of damaging on board computer systems? Thank you for all you do and helping us understand electrical.

I agrre with you on load testing a circuit. It saves a bunch of time

Hey Dan, I bought your tool and your book and I do love the concept but I want to make sure I don't cause myself problems. If I am testing from the relay on the control side, can I damage the computer if I load the circuit with the Load-Pro?

I trust the Voltmeter with the LOADpro it never Fail.

Trying to get guys in my shop to buy these leads, showed them just yesterday how quickly I found a resistance induced problem to the vehicles horn without wasted time with these leads.

Hi Dan. I've really enjoyed your tutorial videos and have found them to be very educational. I do have a question about using the Load Pro on pcm circuits. The instructions say not to use them on the computer inputs. How would I diagnose a 5v reference circuit with the load pro tool? Or the sensor circuits between the pcm and the sensors? It would be greatly appreciated if you could demonstrate this. I can't find anything on the internet on this.

Great job.

I purchased the load pro about a month ago and was wondering if this would work to load the battery cables to look for high resistance..or would that be to much for the tool to handle ??

Just bought the EL 180 LoadPro test leads off of Amazon. I noticed that there is a 181 version. Is there any difference?

Hi dan I have one question about using loadpro leads..when you do the voltage drop pressing the button on the loadpro lead ..will it make any damage to the circuit or lead when you press the button for long time? Thanks

Dam good teacher the best!! when I get the load tester and go back to a good shop going to be a lead tech cause of this tool

Dan, Can the load pro work on the electronic five volt circuitry. I am not very familair with the computer controlled circuitry, but there being three wires I have read one is a signal voltage from the PCM of five volts(correct me if I am wrong). I am not sure what the other wires do, one may be ground. Could you refer me to one of the videos which explains that.

Dan, I have a set of these leads and I love them but they have shorted out and no longer work. How would I go about getting them warrantied?
