So, with all this extra time not driving anywhere lately and a 2003 Jetta just sitting parked, the electrical parasites drained my battery dead within a week or so. I got it all charged back up and began testing today.
When I connect the meter in-line from battery to the (-) post, after 10-15 seconds it reads 400 mA constant. When I disconnect the interior relay on the battery fuse box. there is no current draw.
Using the TSB 27 08 04, moving to the interior fuse box and with the door open, but latch closed (2 clicks) and doors locked by remote, I am reading that FUSE 14 has 2.3mV drop. This is the only interior fuse that shows any voltage reading across the fuses. The TSB matrix diagram I interpret as meaning 327mA current draw. This fuse 14 is interior lights, central locking system. I keep my interior lights switch in the middle "off" setting, and they usually don't come on at all.
My question is, Now What?!? I assume these results mean that some light somewhere is shorting out? Do I just pull them all out one-by-one until the V drop goes away? Better plan or way to run this troubleshoot? Any comments or links are appreciated. Thanks in advance. Plenty of time to finally figure this out over here...
