One poster fought intermittent charging issues for some time and problem finally turned out to be a bad connection at the ammeter. Failure to repolarize after removing, working on, or replacing the generator or regulator can also lead to erratic charging.

Also make sure the ground reference wire that connects the generator frame to regulator is intact with good clean connections. It should go from generator frame to a fender junction point and on to regulator. If there is no specific screw at the regulator it has to go to one of the mounting screws but should have direct contact with the regulator chassis. Some have connected the wire so it relies on a path thru mounting screws and rubber cushions. That type connection can result in a voltage drop and erratic charging if the resistance changes or the path opens and ground reverts back to various paths thru chassis metal..
