Put on a Speedway 6 volt pos. Ground alternator. Putting out about 18 amps at revved up speed (about 1500rpm), doesn't show charging at idle, belt is fiddle string tight, installed as per instructions with the wire size recommended. Doesn't show much amperage at idle. When I turn on lights or solenoid for overdrive kicks in, gage goes to heavy discharge. Alternator is hooked to battery side of starter solenoid. Shouldn't that alternator put out lots more amps? Tag on it said it bench tested at 50 to 60 amps. Any ideas?
