Thread: new member with anemic charging system

Hello group. 1998 GP GT. 300$. Needs a bunch of work, but was running well. Until I hit a big puddle hard, then drove through semi deep water. It was raining hard. Later that night the car crapped out. Later determined charging at 11.8 vdc. Replaced the alt and battery, no change. Likely possibilities? Instrument panel bulb? Don‘t think so, would have to double check. Fusible link? Assuming I determine that‘s the problem, not precisely sure how, I guess a continuity check, where do I get the material or component? Advance doesn‘t sell it. the pcm controls the alt, right? How would I check the inputs from that? Your input is much appreciated.

The car starts, but problem is alternator is eithet defectove (tje one I replaced) or something is stopping it from dping it's job. Output is 11.8 volts aprrox. Needa to be much higher.

A slipping belt would be obvious?

I did have to replace the coolant elbow. Put a few hundred miles on the car don't think I messed up the tensioner or anything. I'll look it all over I guess.

Yes info on checking pcm and all would be much appreciated. Autozone and All Data has resources I'm told, haven't availed myaelf of any of that yet.

It's a brand new Bosch.

Both alternatore read 11.8 vdc when each was installed, including the reman from advance. I could just replace the serpentine belt and see what happens. Or get a tensioner from a camaro (the kind that doesn‘t have the integral lower bypass tube) ... and see what happens. Hopefully I‘ll have the time to look everything over tonight. See what I can see.

I'd bank on the fusible link if you replaced the alternator and battery. I had the same problem in my wife's Malibu and my brothers Ranger. I'll see if I can find a diagram on google.
