Myself as well... almost 8 months later

You, dear Sir, are a Godsend!! Your video saved me potentially hundreds of hours of banging my head against a wall trying to chase down the crazy symptoms I was having with my caddy (exactly the same symptoms You were describing). Thank You soooo much for sharing Your wisdom and hard work!! I would have NEVER thought to look at the (completely obscured by other things) block grounding cable. Mine was completely severed right at the crimped eyelet that mounts to the block. Thank You again for Your incredibly helpful video!!!!

The little bonus-takes at the end shows that it's hard work and that you set high standards for your content! And it shows your human side! Nice going Paul!

After watching a ridiculous amount of this dudes video's, I was trying to test my speinter starter motor for a no crank under the advise that it was that from a garage doing its yearly test, and i noticed the earth strap was black. Sobturning my attention to it, I moved it about and then went to try again and the thing cranked. Mr Scannerdanner you rock. Im an avid fan. Keep the vids coming, i'm hooked.

Thanks for the time and effort you put into these videos Paul. Even after a good number of years in the trade I still learn something new or how to diagnose something faster. You're a great tutor with an ability to explain things in an easy to understand manner. Thankyou!

Hi, Paul. I've got about 30 years as a diagnostic tech. I hate to seem like a tool salesman, but, Power Probe 3 is a huge time saver. it is a dvom with really long leads. Direct battery hookup can tell you what the battery voltage is and voltage drop on both power and ground sides. I quickly diagnose all makes for a no crank problem. You check 3 things at the starter. Voltage at the + terminal, voltage at the crank signal wire and voltage at the case ground. All while cranking. Loading the circuit is key as you stated. I'm not trying to brag but your Cadillac would have been diagnosed within 2 minutes or so. I learned this the hard way though the years. Now I teach this to all new techs. The Power Probe 3 is a great tool. Yes you can do it with a dvom and test light and long jumper wires. But the Power Probe 3 is all those in one. I tried and quickly returned the Power Probe Hook. Don't waste your time and money on that one. The Power Probe 3 will quickly pay for itself if you make money fixing cars and learn to use the tool. I love your videos and your teaching methods. You're doing great work for future and current techs including myself. Big thanks from Marina Del Rey, California.

Kudos for exposing your human side, teacher. Watched this video in its entirety because I just inherited my mother's car identical to yours including dead battery. It made me smile to remember the first time I learned to jerry-rig an extra ground wire. It was in the '60s .. when I was 18.. and I found it myself. If I had videos like yours then.. then the space-time continuum would have been altered, of course!

Haha the Cadillac strikes again! I was a mechanic at a Cadillac dealer for about 5 years and saw that bad ground all the time. Maybe if they could make a front engine mount out of something besides nerf material, it would be such a problem.

My caddy starter was clicking and I read a post on CadillacForums condeming the engine to ground cable, so thank you SO MUCH for making this video to confirm my suspicions. I loved your colabs with ETCG as well. Keep up the gread vids and god bless!

My exact problem I'm witnessing right now today exact same symptoms and voltage readings, fuel pump running continuously, no scanner communication...I did all same test you did, I was suspecting bad ground all ready but the 2 volts at fuse box was making me look elsewhere and totally threw me off and started thinking bad positive lead wire, I thought maybe anti-theft was causing all this also, trying different keys and such, I even started thinking my volt meter leads were shorting out because of the crazy random numbers I were getting, but like you said a bad ground makes sense if you really think about it, this definitely was a head scratcher, thanks for video I'm going straight to that ground wire when I get back to vehicle, this video was right on time!

Wonderful video!!! Thank you! I have had many electrical problems with my Cadillac and have had quite a hard time tracking down worth while info on how to fix it. This video saved me a lot of time, and aggravation. Thank you from the bottom of my heart as well as my pocket!!!

Thank you so much for the great video. Everyone was telling me it was the battery and starter and I was thinking it was a ground but could not find it. At the end of this video you showed where the ground from the body was . After tracing this wire I found that it was broken. Thanks to this video all I needed to do was replace the main ground wire from the body to the engine. Thank so much!!!!

WOW Paul..that reminds me of my rarely used truck ( 1974) I unhook the battery because of parasitic draw..one day when trying to find it ..I did the ground to block test just like you did on the Cadillac ( not knowing what I was doing ..just brain storming) ..and the same thing occurred ,,and I was stumped ..but on some level though I could have weak ground...which is why I was watching this one ..SCORE

The out takes at the end were a nice touch.

Lmao, love the bloopers. Keep on doing what you're doing man, I know it's probably not easy to pay for, maintain, and make the time to do all of this! Especially with a class, course materials, a kid, a wife, and who knows what else going on. Just want you to know that some of us really, really appreciate your work!

Happy to have found your video!! I thought I was going mad when I started tracking down what I believed was a bad starter issue/harness issue. 2 starters later, lights and everything going haywire, I finally decided to take a step back and check on the symptoms of a bad ground. I gotta say this was a very detailed video and I like how there was a step by step process fully explained on how to diagnose it. Thank you for the video and I'll be back for more soon!👍

Excellent video on Ground testing! Interesting that you mentioned being cautious of having a ring on your finger when doing maintenance. During my Naval aircraft maint. training, they showed us a video of this guy's finger that had its skin perfectly, in its entirety, removed from the bone, when he slipped from a ladder and caught his ring finger on the engine! Glad you stressed Safety while wearing jewelry.

Admiral Nimitz lost his ring finger showing the engine of a WW1 submarine to tourists. I witnessed a steamadore lose half his finger fixing something on our ship. We found it and it was reattached.

Nice- average person may never get one of these but showing this will save a ton of frustration that can be employed to every vehicle. 👍

I'm going through this now... about to go outside and work on a DTS... driving me crazy... Thank you so much... you may have saved my day..🙏🏼🙏🏼🙏🏼

Thats just crazy how that bad ground took everything with it.Good to keep this in mind when trouble shooting for sure.This is why these video's are so good and informative you'd be a fool to not watch and learn from a true pro.

Can't get enough of your diagnosis vids, great job.

I am a CMAT/L1 ASE tech, 30 yrs in GM dealerships.As shop foreman I have seen this exact same failure confuse younger guys.I have taught them to do loaded voltage drop test while cranking or start position to isolate faulty cable.Batt pos to stud,Batt neg to block.Almost always broken grd cable from engine to body on Caddy 4.6 and Aurora 4.0.Good video highlighting this concern.P.S.class 2 data on this vehicle is 0-7 volts.

Great vid, out takes at the end Are brilliant 👍🏻😂 goes to show we’re all human and don’t get it right first time , mr danner your teaching and explaining is nothing short of excellence, keep up the good work

Amazing, ive had two mechanics walk away, but this is exactly what im dealing with, thank you!

Remembering years ago I forgot to attach ground cable, the starter farted a while then the throttle cable started smoking like a good 'un. Lesson learned. Great vid, Paul! 👌🏼

Little more than 4 decades ago my, now long deceased, father in law. Introduced me to the joys of "sparky" in automotive. Clean and reliable contacts was probably the first and most important thing he ever teach me! Never fail on me once. First thing check contacts... clean or replace as needed. From flipper cars to clients cars, it as saved countless hours and head aches. ;-)

As an auto electrical mechanic(which I learned literally everything from you),the first thing I do,is hookup a 20 foot red and black corded jumper wires to the battery and use them as my power and ground source.

Came here after viewing the no crank on a Dodge 2.0 and I wish I came here first. At the end of the video where you said just touching the ground and the starter went nuts clicking that's what happened to my car which is why I replaced the battery (no I didn't check the voltage bad assumption on my part but the car started with the new battery (ground was being made) Then my son got stuck with the car. Turns out the ground wire on the bolt to the starter was loose. Thanks for the video and the reminder that you need to start with the basics. TFS

Excellent lesson. And from a Fire/Medic, yes, lose the rings, chains, and secure long hair to mitigate the injury hazards. Thank you for the info Sir.

Eek! Northstar! Take it away! Kill it with fire! Learn something new everytime from you Paul. Thank you!

Awesome video man. Thanks for having a day job and not trying to be a KZreadr. I love that you're to the point and have lots of experience.

I'm happy to share that my First thought, a strait away was a bad ground :-) so thank you Scanner Danner I'm starting te really learn things :-) And the retakes at the end shows how much work you have to put into these videos, really thank you for that (and it funny :-p ) Thanks from a Dutch fan!

It is really helping video. Many times I encountered to something same situation when ground was going bad from battery to chassis or on the block and crazy things were happening. You added nice shots in the end!

I have a 2007 buick lucerne with the 4.6l Cadillac Northstar motor , first thing your video was a huge help thank you. No crank No start had it narrowed down to the fuse/relay box bc someone could push down on the relays while i cranked it over and it would fire up thought I needed new fuse box until I came across this video, ground wire bad . THANKS AGAIN.

How do you come across these scenarios man?? These are awesome. ....you have too much knowledge dude. Much love

The magic and mystery of electrical systems in autos you are king messiah awesome.Enjoy your videos and I’m glad you found your niche in life

This is something I always try to point out. *Check The Grounds!* The ground side of a circuit is often overlooked. Especially in newer cars,the computer(s) can go ape-shit-crazy without a clean power/ground feed.

Excellent example of "ground-to-ground" volt drop, in a less than expected location. Likely becoming a more frequent occasion as it seems more vehicles are coming with "remote mounted" batteries (Acadia, Camaro...) Nice job...

Awesome video, Paul. You really know how to teach.You draw subscribers like a Kmart blue light special. Thanks for the lesson. You may have solved the problem I'm having with my 1995 Taurus Sho .

i have learned more in 4 month i follow scanner danner than before.

Awesome, this is a voltage drop test in a since. Love the channel.

I like the bloopers at the end. I would also thank you for the info. you put out in your videos. Take it easy.

Really Nice find, I have a friend who i think would benefit from you find. He's got a ford with the same situation he called me for help i told him to check the connections 1st. don't jump around stick to the basics , i'm gonna send him this link and hopefully he'll understand NOW! what i'm trying to tell him . Thanks for your professionalism. Keep on wrenching ;)

Wow, I have a 2004 Cadillac DeVille and I'm experiencing the same issue with no crank and I have a broken motor mount so that actually would make perfect sense So thank you for leading me in the direction you did brilliant man thank you.

@ScannerDanner I'm going to try this. Thanks My Brother!

Thanks so much for sharing and showing us not to be a parts changer. I wish there was a dude down here in San Diego that took the time to show us a thing or two. I'm sub'ing to your online course. Thanks

@0:44 “U codes in all of the modules that we could communicate with.” 😂😂😂 that pretty much describes every Cadillac out there whether it starts and runs or not.

Glad there were no leaking injectors. Very weird electrical issues with bad engine ground. great video.

Larry Hurst In short, the PCM was all screwed up (among many other modules) with incorrect voltage levels through the entire board. It is not a stretch for a particular transistor to be energized when it shouldn't be. Either from a misinterpreted RPM signal that really didn't exist (input side problem) or just simply the output driver itself turning on from a messed up voltage level at the base circuit.

Been having this issue for a few weeks checked ecm, checked key, this is so specific to the issues I'm having down to the headlights and fuel pump not turning off. Thanks so much

Can't hurt to check, you should be able to see them with just a flashlight and removing the plastic cover. It's probably hanging on by just a few wires.

a perfect job for a power probe. it's such a common issue you'd think all car makers would implement redundant block grounds. love the outtakes.

I'm 6 minutes in I bet the ground is bad on the block. My 1998 done the same thing it wasn't the ground I cleaned and replaced the battery ground with no results it was the alternator. Great video and knowledge my friend.

i have a 2008 honda civic 1.8 . i buy from a friend not starting valves were bent so i all ready get head job done. when head job is finish time to starrt it i just rolling over . i check the crank sensor i loose the clip off it then it will get gas and spark but when the clip on the sensor it wont get gas and spark. what you think happen

I put in a crate 350 tbi engine in my 87 R10 truck. I found TDC and dropped in distributor accordingly to #1 plug. I have gone over everything plugged in as I have numerous videos of old engine removal and labeled wires to where they would go when installation of new engine. I just hear a click of the starter trying to engage the flywheel. Checked starter and it is not bad. checked battery and its at 12.54V. I grounded from chassis to battery neg and small line from neg cable to frame. Would engine not being grounded like a braided strap be a problem. tried to also ground previous neg small wire to alternator bracket and it burnt up and smoked quick, but it did get truck to try cranking momentarily before cutting off.

today I could diagnose a brand new car only 7000kms on odo with no crank no start. other mechanics on workshop checked everthing before they handed the car to me. they said they found something funny on ground connector of control side of starter relay. It had 8 ish voltage on there. I remembered the theory you tought me by this video and attacked the problem. I checked the ground of control side on starter relay goes to engine block. checked voltage between block and bat neg. 8 ish volt was there. and finally found main power ground of engine block was losen by incorrect torque setting from factory. Many thanks Paul.

@ 15:45 is that looking from the top still? I can see the first part you are talking about under the line/under the fuse box but I can't see or move the lines to see where it connects to the block. Thanks

Yup my wife fixed our 2006 oddesy (confounded 2 mechanics already, whom replaced the alternator other the starter).. good that she refuses defeat...hours of videos on schematics, and circuits and every beatification panels and plastic removed from the car ,she stumbled on your video last.. heard a scream, "omg thats why I got a spark on the block when I was trying to use a screwdriver on solenoid and starter" as she was running outside (yes I may have stated my concern for her frying the whole system)..she found the ground wire in, idk, a minute maybe...eternally grateful, she saw your video before she took the van "down to the studs, so to speak, if I have to" .and she would've I tell you

Very nice video, actually I had this issue on a Cady before, but in my case the ignition switch was stuck as well!

Great Video! Never overlook the obvious! I'm going to check my grounds.

Thank you it saved me so much money

Superb Paul just shows how easily we can be mislead

Thanks! I now have hope. Heading out test that side of my engine.

Great video. It’s a good example of how following the fundamentals in electrical diagnostics will save you time, money & gray hairs. I have a long length of Cat-5 Ethernet cable that I keep around to use as a long jumper wire. 8 wires in the cable, each more then capable of handling anything a car battery can do. They are also color coded so you don’t need to worry about mixing up which wires are connected to power and which are connected to ground. The wires are also solid & tiny so you can stick them into connectors to bypass suspect wiring harnesses to sensors etc without worrying about spreading the connector apart. Since there are multiple wires, you can do that with multi-pin connectors fairly easily too. If you use this trick/technique in a video, give me a shout out. :-)

Outstanding video!

I'm checking out your video cause I have an 2003 with intermittent starting issues. When the car is shutoff and heats up after 5 or 10 minutes it won't start, click, click, click. When it's cold it always starts never an issue? We checked the battery the alternator and it has a new starter so this video gave me somewhere to go, the engine ground and or the CPU ground. Thanks

Well done, you are a genius.

Nice diagnosis!
