Alternator problem? No charge


Hey guys, ive been stuck in this problem for the past 4 days, and my car still wont act right. I have a 96 tercel, first i thought it was the alternator, which my guess still is, i put a new one and if i take the ground feed off the battery it shuts off. I get 12.13 volts at the alt, and 12.12 at the batter. Car runs fine if battery fully charged but after driving for a while it stalls out and wont turn on scince battery dead. Any ideas? i have tried jumping a wire from alt to battery direct because i thought maybe the stock one is rusty or something, still nothing. Also put more ground to the engine and still nothing...

12 volts at the Alternator is not enough. Remove your alternator and remove the cap on the end opposite the pulley. Remove the plastic brush holder assembly and have a look at the brushes and armature end. If it is a Denso one, there should be two copper "rings" or lands that the brushes run on. If they are not too deeply grooved, you can just buy a new brush holder assembly and install. Take the whole thing with you when you go to the local alternator/starter/electric motor shop. That way the grumpy old guy that likely works there can identify the correct replacement(s). If you are lucky you will get out of there spending less than $20. If you are really lucky, you will now have an alternator that puts out 14 or so volts.

Replace the battery cable ends, even if they are clean. Don't ask, just do it.

Also, check the burnt wire at the starter.

I would have to agree, I did not know it was new or the second new one.

Time for knowledge....

Check the connector. With key on all 3 terminals should have power. If not look for a blown fuse both underhood and inside.

oh, btw, if you have a voltmeter why are you pulling off the battery cable with it running? That can blow an alternator very quick.

I do build alternators for a living. :deal: The I or ign terminal is the most important as it turns the regulator on.
