HI
I have a 68 Stang with a 289. Just recently the battery went dead so I charged it and everything worked fine for about 6 hours. Then all of a sudden the alternator started overcharging the battery at 18 volts. Now here's the weird part, If I'm touching the brake it shows a dead battery, one day I had the car running turned on my heater and started to put up my top and the car died. But when it fires up it overcharges. Everything to do with the charging system is new, battery, regulator, alternator and my starter solenoid. I know for sure i have a short but I haven't a clue where it could be. I've tested most of the wires in the engine compartment and inside the car, but am totally lost. Any good ideas
