I'm not sure if this is a problem or not. The charging system on my 69 Mach seems to be charging too much. Measured across the battery terminals with the engine running I get 15.2 to 15.7 volts. When I first brought the car home last fall it had acid coming out of the caps on a repro Autolite battery, chaulked it up to a junk re-pop. This is the readings I'm getting now with a new "sealed" battery installed. The regulator is new and the alternator checked in spec at NAPA. None of my manuals list normal voltages, are these too high or am I being too cautious. Thanks for any advice.

Buzz out all wiring in charging system. One of the wires from the alt to voltage reg may be open or shorted.

Good luck...
