Had a coworker that relaced the battery, alternator and cables. After a week of sitting idle the battery would be dead. He got so mad he sold it to me for $500. This was in the early 80s and the car was in excellent shape. I got the car home and parked it in the driveway. That night I looked outside from the upstairs window and thought I saw a little glow from the car. It was the glove compartment light. Removed the bulb and drove the car to work for 4 years with no problems. Your videos are very helpful. Thank You.

I applaud you for sharing what you know with the youtube community. @404 your meter was actually measuring 250 mA (0.25A), not 25 mA. You are correct that ~50 mA is a typical and acceptable parasitic draw. If you had waited a minute or 2 after connecting the leads in series, that 250mA would likely have dropped to the expected 50mA draw. Additionally, you were completely correct when you say it takes a while (some vehicles are quicker than others) for the current draw to reach steady state and stabilize. Most vehicles take

Radio fuse was the amp drop but could have other components on it. Just this week it is drawing again. Even has kill switch I/O on underside of dash. I have to trace this circuit as you say.

Unplugging fuses and plugging them back in can wake up the car again. The best way to pinpoint it with just a DVOM is to do a voltage drop across each fuse, with the meter reading mV. Power Probe has a chart that shows what mV reading equates to what mA draw, depending on the fuse type and size. Your voltage drop at each fuse should be 0mV. If you have a voltage drop across the fuse, it’s because the circuit is still active. Once you’ve pinpointed the fuse that’s the culprit, you then have to figure out what that fuse powers. Let’s say there are 3 components that are powered by the fuse that has a voltage drop reading across the poles. Don’t take that fuse out, but put your meter in series to read out the mA draw at the battery, and disconnect the given components one at a time until the draw goes away. When it does, you know what was causing your issue.

Tips: Parasitic draw problems can be very diverse, so it is hard to say which testing method is better than another. It really depends on the symptoms and the complexity of the vehicle and its electrical design. 1) Start with the battery charged, this is good advice if you have time. To fully charge a battery could take up to 12 hours or more, and batteries exposed to parasitic draw tend to arrive at the shop practically dead. I think what is important is that the battery is not dead. Perhaps 75% SOC may be more realistic to start testing. 2) The vehicle must go asleep and make sure to put into a state where the customer leaves it during the draw, like locking the doors for example. If it is parked in a garage maybe the customer does not lock the doors. Keep all test leads and hands away from any electric cooling fans. If there is a hood switch for a light or module this will have to be disabled off. Same with a trunk light and or switch if you want to troubleshoot fuse panels in the trunk. 3) Like in the video, if you remove the BAT NEG lug you will reset the system. Parasitic draw in newer vehicles may require a special sequence of operation to show itself. If you interrupt power the problem could go away until the customer recreates it. That is, recreates a special sequence of operation. So, if you want to introduce an Ammeter or a shunt you have to do it without interrupting power. Parasitic draw current profiles may be complex, meaning periodic ON/OFF or something more complex. So the current meter reading may be dynamic in nature or perhaps periodic. 4) I use a clamp meter first, if I can fit the jaws around around one of the battery cables, like the B&K 316, which has a resolution down to 1mA DC, and also measures DC Volts. If you use a clamp meter you can easily go key on. I would have to say that the clamp meter is more useful in this case than a DMM with a 10Amp current range. There is a danger when going key on, obviously the vehicle will wake up and draw a lot of current, and might even turn on a large load like a cooling fan or pump motor. These higher currents could overcurrent an inserted DMM amperage limit, which may blow a fuse. What if the battery is in the trunk? Well if you have a wiring diagram the main power feeds usually come to underhood fuse boxes before going to other interior fuse panels. Usually like two. If you can get to these wires you can use a clamp meter to measure the current. 5) The real issue with complex parasitic draw failures is they can take a long time to diagnose. Maybe even over an hour, after the vehicle has gone to sleep, depending on the vehicle and what has failed. If you know what you are doing and using a clamp meter you can use a DC power supply to put the vehicle on "life support" while you are troubleshooting. Just like using a voltage regulated power supply during Flash Reprogramming which also can take a long time, meaning don't rely on the battery to supply power during the testing. If power is interrupted or inadequate the problem may reset. For parasitic draw I would recommend an old style 15VDC 20Amp voltage regulated linear, current limited, bench power supply. The output is very low noise as compared to a switching power supply. Match battery voltage, connect, and then increase the voltage so that the battery is taking a very small draw (charge). Now you can keep a constant voltage while you are doing the testing and slow charge the battery. If you have to go key on to key off to diagnose the parasitic draw problem remember a load may be actuated. The battery can usually supply the starting surge for a motor and then the supply will take over.

I don’t understand how the hood light or dome lights could work if the negative battery terminal is disconnected. I guess I’ll disconnect it and see if they still work, but maybe they can still draw power unless turned off? I guess that’s why I’m not a mechanic or an electrician. Lol thanks for the great info. It’s a good place to start.
Helps to do a quick Google search on your car Most the time if you start with the common draw makers you'll figure it out quicker then pulling fuses and that really helps if don't have helper

Excellent tech video. Here is a question if you please...Did the full described mA test pulling fuses in the engine compartment and cabin fuse box, had NO CHANGE with a constant 5.43 Amp draw. Did a alternator diode test for ACV with NPF. Gutted the over wired aftermarket alarm and Jensen stereo BS. Still no result. Only thing outstanding is a slight dome light glow after it times out with doors closed ( doesn't go completely out. ) My next attempt will be a complete computer unplug, something is still drawing near 5 A not the desired >.50A. Any clues appreciated ? Thank you

Instead of pulling out fuses, it is easier to measure the voltage across a plugged in fuse. The fuse is a very low Ohm resistor and will create a very slight voltage drop in the mV region if current is flowing through it. This voltage drop can be measured with a good multimeter.

How will the lights be on if the battery is disconnected?

Thanks. Will a batttery maintainer balance out and solve a small parastic draw? After 2 months, of driving just to get groceries 2x/week and then one day I happened to not shut the door while buying groceries, 20 minutes, and then dead batttery. It took a jump to get started. I got a new Battery still under warranty. I then bought a Noco Genius2 2amp maintainer after letting car sit for 1 day, and clamped on maintainer, it went full charge, and then trickle charge this new battery. I clamped it and started car, and it still turned that ignition sound, and started but took like 4 seconds of ignition holding. Usually this slow 4 seconds , but it does ignite, was when I let the car be parked for 4 days. Now I’m confused if I somehow overcharged my battery. Optima battery, Ford Windstar 2001.

I’ve got a 1988 range rover classic. I have an aftermarket sound system with an amp and sub woofer. I suspect this is the issue. My battery is always dead. I’ve replaced 4 batteries in 6 years.

I’ve been having battery issues on a vehicle I recently bought. The issues didn’t start until it I started using the aftermarket remote start. I replaced the battery and the problem went away. Just this morning the new battery was dead and a jumper box wouldn’t work because it has a safety switch. I’m more than certain it’s the remote start.
