Let start with disconnecting the AC clutch from the compressor and then start the car and turn the AC on and see if the charging system voltage at the battery hold at least 13.5 to 14.0 volts. If it does then plug the compressor back and and recheck the voltage and post back with the results and we can work from there to try and get this resolved.
If it stays running with the compressor unplugged and the charging system is charging properly then that usually means the compressor clutch and or the compressor is bad.
Well then I would have the charging system tested to make sure it can handle the added load of the compressor, normal charging voltage should be right at 13.5 to 14.2 volts.
Okay so what is the charging voltage reading with the AC on as well as off?
Okay check it and post back and we can work from there.
