The BEST Way TO Perform a Parasitic Draw Test

So what do you do when you find the draw? Look for bad grounds replace the fuse or please help

Thanks for this method much better than the pull fuses method (which works) that takes soooo much longer as you have to wait for the car to go back to sleep upon reinserting the fuse. Absolutely brilliant.

Couldn’t find any charts on their web sites

Posted 6 years ago, I'm still searching.
What was wrong with a Ford model T

UTI student? I have the same multimeter, it was their recommendation and I’ve had it since 2005.

I hear ya there..I had hair before I started & I am bold now 😅 ..

Electric car problems drain my Brain. Easy Fix anybody?

After watching dozens of these videos, I decided to install a battery tender and park nose in from now on close to the outside garage power outlet. Maybe I’ll get a Tesla decal for my Journey. Of course the genius engineers at Dodge put the battery behind the bottom of the fender wheel well. Inner pan.

Excellent! Subscribed and video saved.

This guy never heard of an Ammeter ?

Can I ask why exactly you needed to open and “latch” all 4 doors? The only one you needed open was the driver door.

i was very surprised to see that the fuse itself creates enough resistance to result a voltage difference.

NOT the best way to do a parasitic draw, especially if it's an intermittent draw. The old tried and true way of putting your meter on Amp, putting it in series with the negative side of the battery works better. THE ABSOLUTE BEST WAY is to use an Amp clamp style meter placed on the positive cable, and then do the voltage drop tests!

Confusing… you start out showing no problems with radio and then go on to check for excessive draw. I’m more confused now than before I watched this

This guy is easy to watch and always adds little touches of experience that simply following an instruction manual doesn't give you. Always good to see a Humble Mechanic video appear in my Google search results...

This is a terribly flawed method. To find out why, check a video by fordtechmaculo.

Epic video!

Oh man, I've done auto electrical with great success for decades, yet I guess I need a lesson in basics because I'm not getting this. Can someone explain to me what's going on when you're getting this voltage drop across a good fuse? And why would that figure vary between different value fuses? I would think that continuity is continuity, I'm seriously not understanding something here.

Excellent video mate. Many thanks.

I love that you still have your UTI DMM

Can someone post a working link to the charts? the powerprobe site has removed them.

Thank u so much man ! You are making me feel confident on trying to fix a car I just bought g37 is killing its battery after 4 hour or so

Awesome video. 👍🙏🙏🙏

I have a Klein Tools MM and the "Resistance" section has many choices (2k, 20k, 200k, 2M). Which one would I use to test the leads? Thank u!

Awesome content! I love the tip to tape the door latches. Thanks!

Its obvious where the current draw is….
He had the fuse in upside down…
Geez….

Now this is what I'm talking about! Just the video I needed! My husband is a master certified mechanic but it usually comes down to me fixing our vehicles. He says he will look at the car but I have a deadline of two weeks to get it fixed. I have a feeling ill be using the information from this video here soon! Thanks!

Each time he operates the lights, radio or anything, is he waking the ECU meaning he must wait till it goes to sleep again?

Thanks pelos

Those 10 min were 10 years. This dude could teach anyone, with more than half their life left, to color inside the lines.

What if you have grounding issues?can you observe thay one with this method?

My battery is dead within a hour 😅

How does the locking latch help for the footwell lights when doors are open? Most cars have sprung push button things in door area that depress when doors are shut to switch off the footwell lights when doors are open....

When I learned how to drive, the '68 Buick I bought had a battery in it that lasted 7 years with New York's cold winters. It seems car technology is at the point where it does nothing but give people problems. Another perfect example: those stupid touch screens.

Thanks for this nice video.

I did the test and found 61.2mA draw as per this test. However, when I connect the meter in series to negative terminal. I am getting a draw of abot 125mA. Not sure where the excess draw is coming from.

I am a bit confused here, so let us say a circuit is live & it is consuming current. Now measuring voltage across a fuse means we are measuring across just a wire, how comes there will be voltage drop when we are measuring across fuse. I am confused

GET A SHAVE !!!!

Well I found the issue now I can't unlock my doors that I latched 😢

1006 ma, equals?????, 0.1 american amps

Great video. But - I searched Power Probe's site and I can't find any reference to Fuse voltage drop charts. The URL you listed above seems to show a much older Power Probe page. Do you know where I can find them?

Sir is there such a procedure that whereas a test light will reveal or perform an outcome that a multimeter cannot (do I really need a test light in my Arsenal or can I diagnose any problem with multimeter 🤔

Shave your face before it gets caught in a power tool.

Hi, HM do you know if this works for 24 v vehicles? I need a good method to test trucks.

This video was extremely helpful. The guys at the auto shop couldn’t troubleshoot the problem and I had 3 weeks to wait to get it in to the dealer, so I did this test myself and found a failed rear wiper drawing current.

Thanks for the help!

looks like power probe changed their site. no charts. doesnt look like your video at all. only products now...

why do you use two meters? one for the battery and one for the testing?

Hi guys, thank you for a helpfull video. I have a battery drain issue in my VW T5 - 75mA in idle mode. Found by removing one by one fuses, that if disconnecting this rear air con control unit, everything became ok. The trouble is I got another used one from a friend, put it in and the battery current drain is back. No idea what to try now…any tips please?
