new battery and alternator not charging

terrible connections will definately cause that problem. However, I have received numerous junk alternators right out of the box. I alwaYS HAVE THE PARTS STORE HOOK UP THEIR ALTERNATOR ON THEIR TESTER BEFORE i PURCHASE IT, i WOULD BRING IT BACK TO THEM TO SEE IF IT'S ANY GOOD. IF GOOD, I WOULD DEFINATELY REPLACE BATTERY TERMINALS, ALSO YOU DIDN'T SAY WHAT TYPE OF ALTERNATOR IT IS.

[QUOTE=Rugratt69;18538203]If your alternator (battery or charge indicator) light is burned out then your alternator won't charge. When you start your vehicle the bulb supplies just enough resistance to trigger the alternator to begin charging. Some have replaced all of their dash lights with LED's, including the battery light, and many have discovered their alternator won't charge. Putting the regular bulb back in for the alternator solves the issue.

The battery light should light when you turn the key to "ON", without the engine running. As mentioned, the current through the bulb is what triggers the alternator to start charging. Not sure what the dash layout is on the '92, but on my 90 and 91, that little battery light is easy to miss at start up.

There is a resistor in parallel with the instrument cluster bulb that is used to supply a current path if the bulb burns out. That resistor could now be open or has a bad connection. I have seen a few examples where the resistor is missing from the factory. Since the OP states the bulb has never lit up, but the alternator was previously charging, I suspect this is not the case but something has happened. Time to pull the cluster.
