I have a 1982 Honda nighthawk 750 that wont charge the battery. It has had 3 new voltage regulators put in it. 2 new batteries. When i put my ohm meter on it and rev it up it shows its charging. But when i take it for a ride it will just lose battery charge. Thats even with push starting it and not using the starter. Anyone have any idea what the heck else would cause this??? maybe a ground problem??
