How to Test and Find a Parasitic Battery Drain (Key Off) Video.
I was kind of put off by the guy's persona at the start of the video, but the info is logical and good.
I knew how do to this, but I watched the whole video and learned some vehicles had more than one fuse box which was something I did not know. The test vehicle had 3 fuse boxes!
