This is prety awesome. So the test light just jumps the Negative cable to the Negative post with it off/separated? I get what yiur saying about the reset/false readings after a while. I bought a really nice low milage 89' seven series bmw years ago from my neighbors cousins wife, the cousin passed away. Great car but had a parasitic draw of sorts. I had no idea how to figure it out. This would have been very helpful to get the car starting consistently again. I had dealt with engine electronics before obd and into obd, but i had no idea how to test body/chassis electronics then. Sure trouble shooting one circuit is easy. But finding out which one is hard. This helps. Great tip/video man

Yes. It's pretty neat little trick that makes no sense. Lol. I don't make the rules I just live by them. But ya you are just making contact with the test lead instead of the cable directly.

Cool i will try it

One thing everybody, in order to accurately test for parasitic draw on today's vehicles you have to wait for the computers to go into "sleep" mode before you start checking or pulling fuses. The light surging bright can easily be a module- body control or 4wd in this case- powering back up after the fuse was replaced. Setup your test light or multimeter as shown and wait about 45min for all modules to go to sleep, then start checking

I mentioned that at the end of the video. Did you leave early? Lol
