Hadnt drove it in about 2 months. My wife says she drove it once parked it and when she went to drive it again it was dead. She said it had been raining alot. Well i got a new battery and it drained over night.. Nothing was left on, no fancy stereo.. Charged it and went for a drive.
Fan Brake and batt light were on and volts were at 18+ . So i got a new alternator. Installed that yesterday. Went for a test drive and all seemed well while warming up. No overcharging no dash lights. Them i redlined it in 2nd an top of the gear volts shot up and lights came on... Overcharging again.... Any ideas?
