then you need a little more rpm to get the alternator to charge above the battery voltage. About 13.5 volts. The average alternator is now between 1,300 to 2,100 rpm. I set up an old 35 amp alternator to run off a 1/3 hp 1,750 rpm washing machine motor at a 1:1 belt ratio. Using the stock regulator would stall the 1/3hp motor. I put a large adjustable resister on the field connection of the alternator.
A malfunctioning external regulator does not disengage properly, which causes the alternator to overcharge, AA1Car.com explains. This is the part of the alternator that regulates the amount of electricity the vehicle needs to perform at varying speeds. Alternator output is another reason for overcharging. Re-manufactured and replacement alternators are larger in size and offer a higher output than stock alternators. This causes inefficiency in the pulley on the belt drive, which causes the alternator to rotate more.
