thanks for the input but the generator is an ac marine generator which is
brushless and uses a rectifier instead to produce the voltage.

Check the brushes in the alternator.

An 8 kw genset most likely has brushes - riding on slip rings not a
split commutator. If it is truly brushless, it will probably require
disassembly to have all field & armature winding connections/brazings &
circuits checked. Have you checked the exciter circuitry?
