Another great video. I started using Di Grease on my terminals like you suggested which has fixed my corrosion problems. Can you please do a video on rack replacement on the '08-'10 edge or similar vehicle. Space looks limited and the repair looks a bit scary because the sub frame probably has to be lowered. My rack doesn't leak but I can feel the play is in the rack attaching to the inner tie rod. It's moving all over the place especially the y direction. I've heard to check the U joint but that wouldn't explain the play in the rack itself.

I am a retired electrical technician with 44 years of experience and I have to say this is the best video I've seen to troubleshoot a parasitic drain on a automotive battery.

For inexperienced folks, take a picture of the fuse box before you start, you don’t want to mix the fuses and put them back wrong

Hello Brian: I watch all your videos & am impressed by your no BS approach to troubleshooting & effecting repairs, properly done, & expertly executed. Parasitic draw can be a real challenge & I use Fluke meters with "max-min" capabilities, & I use a Fluke "amp clamp" & I have "centre zero" ammeters that shows the direction of current flow as well. I am NOT a mechanic, have no certificates or licenses as such, but I troubleshoot & repair electrical, electronic, & hydraulic faults with agricultural equipment. Tractors, trucks, combines, swathers, air drills etc.. I am 80 years of age & I don't do any physical work....I tell people to remove a part, or to crawl into some restricted space to put a meter lead on something or other, & I interpret the meter(s). I am amazed that mechanics, generally speaking, have little or no understanding of electrics or hydraulics. I always laugh when I am asked where I went to school to learn how to fix these things. I made my living at communications radio & radar, & I still do "call outs" for oil & gas companies to fix SCADA equipment. It keeps my brain active & the challenge is a lot of fun. I was pleased to see you open your own shop Brian, because I know you will do well. You are the right man in the right job. Cheers! Brian

Great video. One more step I like to add when there are multiple fuse boxes and that there's not too much trim to be removed to access the wiring to it, I go amp clamp on battery first, then I move to the power distribution block that splits the power to the different fuse boxes. This way, you can pinpoint which box the draw is coming out off. Saves you many fuaes to check. I work at Mercedes and they have A LOT of fuses to check.

Been a pro tech for over 20 years, just started at a Ford dealership. Became one of the top diagnostic guys real quick. I have to say, I've learned a lot watching your videos, Thanks.

Brian, that was invaluable!! Those intermittent parasitic losses have aggravated us for YEARS. Your method is sound, and thanks for disproving what some say is the "right" method! I'm going to tell you an old story, if you've got a few minutes. I was a Lincoln/Mercury Line Tech, a few years before you.... EEC II and III were still out and harassing us!! 😖😖 EEC IV was only recent then, when I had my only claim to fame... 1991, the first Town Cars on the Panther platform were hitting the market. Several were coming in with heavy Battery drain concerns. Immediate diagnosis was the Voltage Regulators. So Techs replaced VRs and Alternators..... But they kept coming BACK. Same concern! SOMETHING was killing VRs... And guys were searching miles of wiring, to no avail. Customers were of course, getting frustrated. So were we! One day, I decided to get fundamental... I opened an EVTM. Almost by accident, I FOUND the problem! 91-92 Panther Vehicles WITH Heated Windshields - the CHARGING CIRCUIT went from Battery to Alternator, to *Heated Windshield Module,* to Voltage Regulator... And the Vehicle I was working on, had a Cracked Windshield. Turned out, the crack in the Windshield, SHORTED out the Heated Windshield Module, thus losing any signal to the VR!! 😳 .... After fighting with the Dispatcher, I got to order a new Windshield and Module. Didn't touch the Alternator or Regulator... FIXED permanently! Ford ordered a TSB (should have been a recall) for a wiring Harness shunt between Alternator and Regulator, and changes were made by the 93 model year!! You ever come across an issue like that? Carmine ✈🚂🚙

The man sure goes the extra mile to produce these outstanding videos. No problems here, I just thought it would be interesting, which it was.

I've used the old tried and true method for years and I appreciate you teaching others how to do this properly. good job

Yes sir and they have a bunch of ground issues also.

I'm old school, I have been using various combinations of these methods for years. Starting with the amp clamp to determine how much draw there is and whether its constant or intermittent. The result determines the next step, if it's reasonably high draw even an IR thermometer can tell you which fuse it is. Totally agree non invasive is best, pulling the wrong fuses can set all sorts of codes and require a scanner to erase them again. This adds more time to the job and cost to the customer unnecessarily.

thank you for showing the difference in each way of diagnosing a power draws

What a great video! Thank you for taking the time to show the different methods and what works. We have been having an issue for close to 9 months off and on. We have a f350 6.0 2005, had a shop put in all new injectors, HPOP and they installed a used wire harness. A week later I was at a stop and it died in gear. Brought it back and they replaced the batteries (I know….stupid). Got it home and a few days later same issue. We then bought an alternator and installed it ourselves. Truck ran great for about 6 months. One day, drove to work and parked. About an hour later hopped in to run to the bank and the tick sound happened. Batteries dead. Batteries tested bad and decided to buy new batteries and another new alternator (thinking it was a bad alternator-it happens). Installed all ourselves. About 2 weeks later, hop in to go to work and she wouldn’t start. Battery output 11.6 and dropping. Jumped the truck, let her run about 5 mins and tested batteries. Output dropping as she was running. Went from 11.5 off to running-dropping down to 9.6….I’m researching what would cause draw intermittently. It happens sometimes and usually is fine for a couple months once we replace alt and batt. We are at a loss.if anyone has any advice, I would appreciate it. I am sorry to asking here.

Could have used this video a week ago! Ran through these same tests and found my rear wiper on my 2004 Ford Expedition had the same problem. Very Ironic. Thanks for all your Great videos!

Excellent video! Thanks for clarifying the shortcomings of the voltage drop test. Keep up the good work.

An alternative to an amp clamp is to use two meters, one as an amp measuring device and the other as a millivolt device. I would suggest this as you can get the vehicle to sleep and then use the min/max function to monitor for awhile to determine if you have a major draw without having to visually monitor the amp clamp for a period of time. Excellent video and explanation of the various methods and reasons for using two methods at the same time.

I have a 2009 Escape that was running the battery completely dead overnight (now Jan 2023). My strategy was to pull fuses but that takes a long time. Due to brilliant Ford engineering, the rear latch is inoperable (apparently a common problem) so that was my first thought. Nope, still went flat overnight. Did some searching and found a number of complaints about the power seats shorting out so I pulled that fuse. Nope. Then my brother-in-law sent me this video. With the engine running, I turned on the rear wiper and it did not operate so it suggested it was the problem. I pulled that fuse. That was the problem so I did not actually have to follow up with this process. Thank you, now I know the best approach to do the parasitic draw testing. I have a decent DMM but not the amp clamp. And also much thanks to the brilliant Ford engineers who designed the circuitry to allow the rear wiper to run the battery flat overnight, such a genius approach to drive more people to the Ford service centres... Ridiculous.

I’ve fixed so much on my ranger because of this channel keep up the good work

This video is gold dude, your a joy to watch

Thank you, this worked great. I don't have an amp clamp, so I used the tried and true method. My fuse box is under the hood and trunk, so I just shut everything off and closed the doors, didn't lock the doors because that would turn on the factory security system. Hook up my meter to neg side, heard something clicking towards the back of the vehicle. Meter reading was 4.56, after a minute or so it dropped to .19, let it sit for about 2 hours then went and checked it, .02. So my parasitic draw is under .05 milliamps. Great method, thanks.

Very easy to understand actually. Thanks for sharing. You're the first one I see using this complete method.

This is so spot on, I was just about to search for this exact thing when the video popped up 😊

We use the traditional amp meter in series at my Ford dealership. I never thought the mV to mA reading conversion method was a good idea. Also love how you also use a shop rag to insulate terminal end from the battery post. A Senior Master at my dealership showed me that trick! Pretty slick. I also use a parasitic draw tester set of leads that have much larger amp clamps that can easily fit over battery posts. Plus if you make a mistake and over load meter it's a simple ATO fuse to change that cost pennies. We also try to have a draw of 20 mA or less. Always love your content!

As a non-mechanic, I once had to track down an intermittent drain in my car. I do do electronics, so I tried connecting a multimeter on a low DCV range (20mV or 200mV, I can't remember which) between battery negative and the vehicle body, basically using the negative battery lead and its ground connection as an in-situ current sense resistor. That gave me a reading I could roughly calibrate by comparing readings with/without headlights on and using the nominal power draw of the head/tail lamp bulbs, and meant I didn't have to disconnect anything to get usable information. I made up a long lead on thin wires with croc clips on the battery end so that I could have the meter inside the car where the fuses were, and since one wire was ground and the negative battery connection was virtually at ground I was happy to have them (suitably taped down) running out from under the closed hood and in round the edge of the passenger door to the meter even while driving, since there wasn't any risk of high currents flowing even if they ended up getting pinched or worn and grounded to the body. Not a precise solution by any means, but easily good enough for me to track down the issue (fan thermostat causing a slow intermittent drain which didn't seem to be there when everything was fully cold, and which would only start after running the engine and then letting everything cool down for a while).

Always love your videos! You do such a great job of explaining technical information to make it understandable for everybody of any technical skills level. Thank you so much for this video and all of your other informative KZread videos. I’m gonna have popcorn ready next time I watch one. You keep our interest peaked to the very end!

As always, both your methods and explanation of why are very accurate and honest. Thank you for all the extra work you put in for us mere mortals! Please keep up the good work.

You make a good point, intermittent problems are always the stumbling block. My amp clamp isn't very accurate at low current levels, but the ability to measure without disconnecting anything is lots easier. Also you'll never fry the amp clamp like you will if you exceed the 10 amp maximum in line. What I like about the drop test across fuses is that (when it works) you quickly know which circuit is involved. Even in the example you showed, it did work when the circuit was drawing current. Excellent point about intermittent draw, and cool the way your IR camera found it.

Very nice job sir. So many people aren't even appreciating that just making a video alone these days is a lot of work and giving up your time for others...yet they have negative things to say. Unbelievable. This was great info for me as I know a good amount about electrical on cars for many years but never got the details on how to do it the best way using meters verses the old school way with a test light. Just knowing the minimum milliamp figure cars put out today is good info to confirm there is no major draw. I do aftermarket work and its all good to know. Keep up the great work....God rewards those who dont just think of themselves!

Thanks for taking the time to show this, GREAT VIDEO.

Great video Brian,excellent for the beginners and the advance mechanics and the diy, thanks for sharing your knowledge with all of us

good job Brian. had the same problem on my escape. this is an excellent method

Excellent vid. Some of us DIY'ers have industry electrical backgrounds and already have the assorted meter collection . So your Ford vehicle experience based tutorials are refreshing.

Thanks. This is the best explanation I've seen for the good and bad of finding parasitic loads. It demystifies so much of the misinformation that is passing off as truths in other KZread videos. Using the thermal camera for the hot fuse That's a great tip. I don't have a thermal camera but not I have a good reason to consider buying one. Great work I've even added it to my favorites for future reference. Cheers from Australia.

If we ever meet up in real life, I owe you a libation of your choosing. My 02 GT has a helluva draw and this will definitely help me identify it. Thanks for posting this up

Excellent I needed this refresher!!! I love the 3rd method for sure!! Thx man as always! Great work!

Thanks for this video. This was by far the best video I have watched on parasitic draws. It was very informative and everything was explained very well. This will help my troubleshooting a ton. Thanks again!!

I never get bored or tired watching these videos Brian is the best

FLIR gun was awesome! I gotta get one of those. Truly terrific & informative episode! Thanks Brian 👍🍻

Great job, well done. I like your method of monitoring the Amp meter while Parasitic draw is occurring and backing it up with the fuse voltage drop. I have done the Amp method draw and did find the circuit that way while removing fuses, but as you say you run into the possibility of "waking up" components, then slows you down.

This is by far the most thorough explanation I've seen or parasitic draw. Thanks for making the video!

I'm currently looking for a parasitic draw on a F53 motorhome.....you are spot on this is the best way I have seen. Thanks.

Awesome video. Thanks for taking the time to help. This problem seems to be more and more common as the standard 12v power distribution system gets more and more complex and taxed with more and more technology and accessory features.

Your comment made me think. Why not go to a higher voltage system. This would allow the use of smaller gauge wires and less of the precious metal copper. Even the standard GM wiring might work properly!

Awesome content my man you'd have made a great A&P technician with the standard of work you deliver. 👍

Thank you for taking the time to record this good video.

Great job explaining the different ways to check voltage drain.

A quality amp clamp and that wiz-bang thermal meter is the ticket short cutting diagnostic turn around time. Thanks for this comprehensive overview using both the new vs. tried and true methods debugging parasitic draw. Great presentation!

great video! Thanks. my 2006 f150 has a draw. if i dont drive it for 3 or 4 days it nearly kills the battery. youve given me plenty of info to tackle this problem if i can just get around to it.

Man this was the most useful video I’ve watched about this issue, very detailed and great step by step instructions helped me find the issue in my Eclipse GST, THANK YOU!

Excellent video, I never used the min/max function on my Fluke but now I know what it does, thank you young fella

Great video and explanations! Heat camera is a new one for me. BTW using a vantage pro with snapon clamp. Shows graphing and max min.

Thats awesome...Never realy thought of combining the two methods... Amp clamp is king in my book for both charging and draw faults...

Except on cars that draws in weeks and not in one night. You can see it even on this video that the current clamp resets the zero value after current spike. Set up at 33:20 (~60mA draw) reset at 34:06 (0mA draw) while DVOM tells you the true value when in line done correctly without disconnecting the battery at any time from the car.

@@timowallin8020 isn't that reset cause some modules are already going to sleep and the intermittent draw also went away?

Excellent. Great job. As a tech myself and with 16 ASE certificates it is easy to remember and using the visual walk around makes it even more easy. Damn engineers.
