Ok heres the deal. I swapped a s52 in my car, no problems. About 2 months or so later the battery started giving me issues. It worked fine for a while, but then loses its charge and won't start the car. I assumed the battery was bad so I got a new one (it was under warranty and tested as "bad").
Well that fixed it for about a week, then same thing, power just gets sucked out and not put back in....
Ok I think, I goto autozone and have them test my battery and alternator, its only putting out 12v IIRC. Cool so my alternator is weak. Anyways the s52 had a 70amp Vaelo on it so I went to the salvage yard and picked up a 140 amp bosch for $30 or so. Well that didn't fix it either! I had it tested AGAIN at autozone and the same deal, 12V.
Well winter came up and I said fuck it for now, I planned on getting it rebuilt this summer when I take the car out.
So I dropped the alternator off to get rebuilt and the guy tells me its fine... Said I have a stead 14.2V on the bench and it took it apart to inspect the brushes and what have you and he said they are all just fine.
So does anyone have any bright ideas why my battery wont charge?!
Heres a few things that come to mind, specific or not.
1. Relay? Is there a relay that turns the alternator on to charge the battery?
2. Short? Could I have been running with a major short all this time?? I checked the 12+ terminal in my engine bay and all those wires for the harness and fuse box seem to be where they should.
3. OBDI conversion. I now recall something with a power wire. There were two red like 2 guage wires on the OBDI harness, we ended up cutting one off for I have no idea why. The guys helping me just said we did to do the conversion. So I have no idea whats up with that.
Thanks
