FYI...Alternating AC current is the wave sign on your meter and the straight double line is DC current.

Good simple video...If it's something other than the computer, that is most cases, always draws a " little "current, like clocks do too....If you find, but can not repair and/or replace, what is causing the extra draw, you can put in a manual disconnect that turns off the power at the battery or a manual, switch controlled disconnect, that can be mounted in the cab, but with more expertise involved...A kill switch so to speak, cheap and simple....Many are made to mount directly on the battery terminal and are easy to install, but you have to raise the hood every time to use it.... I also recommend pulling the computer fuse first, before checking anything, then the others...Just in case....Thanks for sharing this video...It's still a good one.

For years, my car ate batteries. Each year I had to replace the battery. If the car sat unused for a few days, the battery would die. No mechanic performed or even suggested a parasitic draw test. They just kept selling me replacement batteries. Finally one day, I realized that the problem was that the rectifiers in the alternator had shorted. The battery was draining through the windings of the alternator. How do I know this? Because one day I saw a thin stream of smoke drifting from underneath the hood. When I opened the hood, there was an inch tall flame on the alternator, which water couldn't extinguish (because the current from the battery was flowing through the windings, heating them like the filament of an electric light bulb). The alternator was replaced. A draw check confirmed that the current leak from the battery had stopped. No more dead batteries.

I took the stereo out and checked all wiring and it seems good. Stereo works also but cant figure out where its coming from. Any suggestions??

I have a 2007 bmw 328i i swapped 2 fuses which are for the locking and unlocking system because my car wasn't locking/unlocking. After I swapped it out it started to unlock and lock. And when I started the car again it would not start anymore. I had a mechanic come look at it and says it's the starter. Do you think I did something wrong? And my battery is at 11.4V.

You have 2 options, remove the bulbs if they are easy to get to or simply close the trunk latch with a screw driver. When you are all done, don't forget to open the latch before slamming down the trunk lid. The latch method is better since if you have an alarm system, the circuit will think the trunk lid is closed and "sleep" with no draw.

@Monir Did you find a fix? One way is to attach wires at the places specified to attach meter leads. Run wires outside trunk and close trunk. Without kinking wires. Of course, check for drain between your added wires. Make sure no shorts or crosses in your wires. 2nd try. Set everything up. Have a flashlight. Make sure trunk release is working. Hop in trunk and shut lid. Check for drain. Check for electrical drain. Check for kitchen sink if ya want. I took my out.

The multimeter will indicate a reduced amp draw when you find the first offending circuit, but still show a value, for example a 3.5 amp draw goes down to a 2.5 amp draw when you pull a particular fuse. Leave that fuse out and continue pulling fuses one at a time. If no change in the indicated amp draw place the fuse back in it's socket. Repeat until the amp draw is zero.

Hello! I am dealing with a parasitic drain on my 2017 nissan pathfinder that cases my OEM radio to turn on at random times thus killing my battery. Even when I unhook the radio completely from all the harnesses I can see on my multimeter that there is a drain of 3.5 to 4 volts at all times and the only thing that fixes the issue is to pull the extended storage fuse. I have removed the fuse box and found the harness that controlls the extended storage fuse is just a thick copper wire that is hot all the time. I know one of the wires that it controlls is the blue memory wire leading to the back of the radio. Initially I even tried just cutting that wire and running it to a different positive just to see the results and though the radio never turns back on by itself the parasitic drain is still there. I have already spend thousands of dollars at the stealership for module replacements, sensor replacements, radio relacements and all this for them to NOT fix the issue. Now they are swearing that only $8000 more to replace the whole wiring harness will fix the issue. I mean holy crap, who do they think I am and what do they think they are they working on, a Lamborghini? I'm just a regular guy with a family and I need a vehicle that works, especially when I am paying $450 a month for this think. I know this is a lot, but do you have any advice? Thank you so much!

Your vehicle is naturally going to have a draw to it with the key turned off. How do you think your stereo keeps memory? So the light test with the negative terminal is bs. To know if you have a problem you have to use a meter and look at the exact number that its drawing. Example, my mustang Cobra draws .o9 volts when the car is off because its feeding the memory for the stereo.
@nickyjames1430

I have a 24-year-old E150 it runs okay but the battery goes dead after a day and a half just sitting there it's got a new battery the alternator is putting out 14 volts it's actually the second battery that I have in the vehicle that's less than 4 months old I have to put a battery minder on it so I don't wind up in a situation where it won't start if I need to use the truck I do that a day before I saw what you did and I am an air conditioning contractor I've worked with electricity for 30 years what if it's the ignition switch or if it's the computer how do you diagnose that problem I removed all the bulbs in the dome lights so that can't be a problem even if the door switches are bad if the dome light bulbs out there it's not going to draw an amperage is very little to the truck that has anything in interior wise that could be the problem it might be the computer or maybe the ignition switch because I had a problem with it shutting off and I always make sure that it's in the lock position when it's in the off position because I could take the key out no matter what position it's in so I always make sure that it's locked in the off position but that hasn't helped at all I don't know exactly what the problem is I might have to bring it in I SAW WHAT YOU DID WITH THE FUSES BUT IF IT'S THE IGNITION SWITCH OR THE COMPUTER IT REALLY WOULDN'T MATTER BECAUSE I MIGHT STILL HAVE AN AMP DRAW NOT KNOW WHERE IT'S COMING FROM the only way would be to pull the ignition switch and take all the wires off I wouldn't know how to check the computer I guess I can unplug the computer but I don't want to screw with that I'm pretty expensive to replace

Love your personal rags to riches video series and on becoming an electronics expert. Setting up ammeter in series with the battery's ground circuit as shown sounds off my car alarm. What do I have to do differently to do the parasitic draw test?

+omnidivisible You can't disable that alarm tentatively? most systems have some method of going into valet mode.

Car alarm on my 95 Corolla is one thing I would like to disable PERMANENTLY. If I have a valet switch by the driverside kick panel, the toggle may be missing. Owner's manual doesn't cover car alarm. Car model-specific reliable consumer instructions on disabling car alarms are hard to come by and time-consuming, and electronic techno instructions are hard to understanding and follow to be actionable. Toyota dealers would not give me a straight answer or touch it. Would you have any pointers for disarming a 95 Corolla or the critical information and skills I need to have to disarm my car successfully?

Ac voltage is always curvy. DC voltage is line Dash. Maybe that's why it showed no draw on the multimeter? ......

So how come you had a draw on the first test with the power tester and 0 on the power meter????? 🤔🤔🤔🤔 it should had shown that there was a draw on the power meter as well correct? You also obviously show that there was a draw but didn’t show what the issue was, or was the draw happening because your trunk was opened? I’m more confused then when I started watching the video bud. 😕

Isn't the dc the left side and AC is on the right side?

Yep. DC is the static icon, and the curvy line is an AC sine wave.

There are a few tips for fixing a car battery do not try to do this until you know what you are doing - the acid can burn your skin Test the voltage first - there may be a dead cell which would waste your time. Check the battery fluid. attempt to fully charge the battery. (I learned about these and more on Jons mender guide website )

Hello, good morning, I am a follower of your channel and I am contacting you, to be able to comment on the following situation that occurs in my vehicle, Ford mondeo mk2 2.5 v6, one morning the battery was discharged, without knowing how to change the battery, when month or so, the car stopped in full operation, it was as if the electricity had died, stop, giving it and giving it until it started, again as if the battery was without charge, it was only a month old, I changed the alternator regulator , and well, I bought it, it charges over 14.5V, and I considered the fault finished, one day cleaning the interior, I left the radio on, while I cleaned, and nothing a few minutes later, the voltage began to drop, less to less, until the battery was discharged at that moment, I was surprised because that had never happened to him, I did another test, with the battery charged again, I gave the contact, after a short time, equal to less to less , that in a moment the battery goes away, I recharge it, install it, and leave it and connected approximately 2 months, until I realized that the red light of the alarm did not blink, I checked it and discharged, that did not happen in the past either, it carried out the current leakage test with the multimeter, because I told myself that this would have to be a current leak, it is the logical thing to think, and what was my surprise, that the value it gave is 0.02 amps, with the battery just charged, so there is no current leak, I have also performed the voltage drop test and it gives 000v both positive and negative, and then what happens to it? I don't even know what else to do, regarding what I am explaining to you, I await your prompt clarification, please, greetings.

Modern fuses can be tested for continuity without removing them as there are two small metal contacts on the outside of the fuse. So why not test for amps the same way as testing for continuity instead of taking all the fuses out ?

your not checking for continuity at the fuse. you are checking for no draw at the battery after having temoved the fuse that deactivates that particular circuit whatever it may be door light, radio etc. that way you've identified where the problem is. Then you know where to look.
