Don't know that one particularly (you should be able to finds a parts
diagram online somewhere I'd think), but there's a couple of ways.
Either there's a centrifigul relay or one on the generator coil that's
not working or the one on the clutch has a secondary coil that isn't.
Trace the wiring if you can't find a diagram; if you can't find the
other relay, then it's combined in the one.
