So my neighbor has been asking me for jump starts like every other day ... and said he didn't know why his battery kept dying, so this morning, I grabbed my Fluke and went over and said, let's go figure this out ... ultimately, his alternator was kicking out a nice solid 14.8 volts even under heavy load, so we let the battery charge for a while, then after he turned the car off, I put the amp meter on it and saw that the battery was kicking out a constant 300ma with everything turned off, doors closed, key out of the ignition, etc...
So I figured the best course of action would be to start pulling fuses to find out which circuit was draining the battery and it ended up being a fuse labeled as "BACK UP" - whatever the hell that meant, but googling the year make and model with that fuse name turned out some old (10 years in some cases) forum discussions on this exact issue with that exact car ... but none of them ever got to a resolution as to what the problem is or how to fix it.
The fuse powers the head unit ... but this car has an aftermarket unit which I know doesn't matter, but that would at least tell me that the issue is not necessarily with the stereo itself since the blog posts all had stock stereos except for one, and he ended up swapping back in his stock head unit which did NOT fix the problem.
I told him that for now, just pull the fuse when he parks the car until I can figure out how to actually solve the problem.
The vehicle is a 2002 Acura RSX ... if anyone has any words of wisdom, I'm all ears.
Thank you,
