I have a 1946 JB B where the generator is not charging the battery. The system is negative ground. I have carefully tried to follow John T's troubleshooting guide. This guide convinces me the generator is OK and it is possibly the cut-off relay. I replaced the relay with a new one, but still not working. The gen was polarized before I added the new relay so I shouldn't have damaged the relay upon install. I have carefully traced the wiring, convinced myself there are no open wires and grounds are good (used jumper wires to ensure.) The part of the guide that points to a bad relay is where I ground the F-term and jumper between the GEN/A term and the BAT term of the relay. The ammeter show charging.
When I turn on the lights the ammeter shows proper discharge current. I question the proper function of the light switch which is in the circuit from the F-term. How do I know in the proper setup that the light switch circuitry is properly handling the wire from the F-term?
