Default ammeter 1937 ford truck

Resurrected a 1937 ford flathead that was dormant for 20 years and poorly maintained prior to that. I cleaned the connections on the gauges and the ammeter is registering zero when running and discharge when I turn the lights on and the engine is running. The gauge returns to zero when the lights are off. Does this mean the ammeter is simply showing a load or that the generator is not charging or keeping up with demand?

My 35 Cabriolet does the same thing. Since I don't drive at night, it doesn't bother me. My gauge will return to zero with the lights on when I increase the RPM's. I just assumed the output of the generator at idle is less than the demand from the lights and, as soon as the RPM's increase, the output satisfied the demand.

At what RPM is engine running? Does it change as RPM increase? Do you have a multimeter?

is your generator charging or just spinning the water pumps?
