Bill,
If I remember correctly, the way I test a generator is to attach a + lead to
ground on the generator from the battery and - to both the small and large
spade connectors and if the generator spins like a motor it is good to go. I
am sure there are other ways to check out each circuit with a meter. I believe
there is a diagnostic on the web somewhere to check the entire charging
circuit.
