Brush gobbler

[Scott Forman]

Your commutator ring is worn. I went through this in January. You
have three options:

1) Replace entire genset
2) Find a modern head unit that mates up to your engine
3) Rebuild the head unit

I went for option three, as it had the lowest price and fewest
potential headaches. Now it is basically a brand new "old
technology" generator which should last another 20 years just like
the first one did.

The commutator ring must be pressed out, so machine tools are
required.

Good luck
