Charging Issue

it it an electronic regulator or a points style regulator (triangle plug or 2 lugs?) Alt requires power to energize then it will make power, the points voltage regulator turns this power off and on (duty cycle) to regulate the 14.2 V output or whatever to the battery, and then the rest of the car through the ALT/AMP meter. The electronic regulator regulates the ground connection to do the same thing with the isolated field alt with 2 F connections. Both work with their chassis mounting for ground.
