The generator is 30 amps and the field coils draw about 1.5 amps. So if you ohm field to ground it would be like 8 ohms, and arm to ground should be not even 1 ohm.

If this fails, simply clean the connections and check again. Then remove the inspection cover and check for wear on the brushes. There are two generator sections in the manual so I would run through them both; if the brushes are worn, you’ll have to clean the commutator too.
