Inspecting generator field coils
I recently bought a generator from a fellow FB member (thanks Ray!) and I've got it apart to inspect. The field coils are clearly aftermarket. There is some discoloration and I notice they're extremely... sparkly? Is this normal? Is it tiny fragments of the brushes, which I notice are moderately worn?
Contemplating whether I should buy new field coils before reassembly and installation... I have a local alt/gen shop that has Model A experience, so I would be taking it to them.
(I should add, my coupe came with an alternator, so I have no generator for comparison, nor have I ever seen one apart before.)
