This is a 12v 235. I've got an issue with the battery draining after a few days. I've been using my Battery Tender to keep it up. Finally got around to investigating today. I don't notice any other electrical issues except for this. The entire electrical system is new including the AC Delco reman alternator for 1998-2001 Geo Metro. Got this from Rock Auto. I did modify the socket plug to use a jumper to the big lug. With the meter in series from the + bat lug to the disconnected + bat cable, I get .28A. If I disconnect the jumper between socket and lug it goes to zero. Any way to tell if it is the rectifier or maybe I screwed up something modifying the socket to add that jumper?
