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.
I aint no pro but I have seen a few alternators not put out very good voltage when new and after a week or so really wake up. FICM prolly is on the way out if it is dropping to 45 or lower, is it hard to start cold or long start? Mine would be a long hard start when the ficm shot craps the voltage would drop to about 38 then recover and be at 47.
