I have a 1963johnson 75hp electrictromatic. The battery does not seem to be charging. When I pull one of the battery cables engine dies. Where do I start. Would it be the regulator? There are only 2 wires I beleive going to it(box inside boat). Or would it be on the motor,meaning the generator? If so could someone explain test for either of these. Or any other suggestions as to what may be happening.<br /><br />Thanks
