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.
You will have to check it with a digital voltmeter. When an alternator is charging, depending on the level of charge of the battery, it will produce from 14 volts for a fully charged battery to 15 volts for a partially charged battery.hen the battery is fully charged and the engine is OFF, the nominal voltage across the battery is approx 12.6 volts. With the engine running (above 1000 RPM) it should be 14 - 14.6 volts.
