Have 85 F250 diesel, had not been in use for a couple of years. New batteries and started fairly easily. Overnight the batteries were dead, recharged and started fine. Found a voltage draw (with the key off) between + terminal and wire to the glow plug solenoid and starter relay. Removed from glow plug, still had voltage draw removed from start solenoid still draw. Thought might be bad altenator and replaced it and voltage regulator removed from start solenoid still draw. Home made remedy put a switch between + terminal and the wire to the solenoids, no voltage draw, but now the amp meter will peg at 70 amps when engine reved and the voltage goes to 20+ volts. At idle voltage is 14 volts and 15 amps. Burned out the headlights when engine reved up. Took new regulator back and got a replacement, still have highe voltage output and high amp output. Any suggestions
