I have a '92 RS V8 5.0L Camaro. I just recently replaced the battery and alternator and starter. But, I have started to notice that the battery charge drops really low after a night or so, and I have to drive it around for a bit just to charge it somewhat up.

Could it just be that I have a crap battery, or is the problem deeper?

 

No one?

 

Sorry man I have a similar problem also. Still can't figure it out. Let you know when I do.

 

Voltage drain or a short somewhere in the system. Try pulling the fuses for systems that don't interfere with the engine operation. A aftermarket sound system would be my first guess.

 

I'd bet you've got quite a bit of resistance in your electrical system, particularly from the alternator to the battery. Might want to check and replace your wiring with some heavy gauge cables.

 

Do a parasitic drain test. Key off disconnect one of the battery terminals and put a jumper wire between the cable and battery. turn the key to on (not to start)for 15 seconds then to off. Connect your multimeter to the cable and battery and set it to test milliamps, then take off the jumper wire. The current draw should be less than 50 milliamps, if it's more then start pulling fuses until it drops (don't put them back in until you are done) The fuse you pulled when the current drops is your bad circuit.
