Any ideas on Powertech generator not always producing power? (Again)

Try Tony at Reliance electric motor repair in Hudson, WI  715-386-3633  They work on this all the time. I have used them for 20+ years.  Not to far from you.

Since I live in the boonies I always start online, usually ebay, with any numbers on the brushes or with make/model numbers.

Problem here is no part numbers on the brushes at all.  I have not been successful so far locating brushes except from Powertech.  They can't be the only manufacturer who used that Marathon head.

I talked with Tony at Reliance Electric Motor Repair.  I gave him all the numbers from my Marathon head and he contacted them.  It turns out the brush assembly is an obsolete item from Marathon even though the head is only six years old.  I drove out to Hudson this past week and Tony put new brushes in the existing holder for less than $15.  (Powertech apparently has new brush holders still in stock, but not cheap.)

The new brushes are back in the generator as of this past weekend and it is making power again.  I'm hoping this fixes my intermittent problem of no power from time to time.

Very good news!!

Wish mine had been that simple, I've had two dead gen heads in the past year. Never did know what was wrong with the last one and the latest one has a shorted field. However, I plan to repair this one one way or another because it is a very stout genset.

My theory on brushes is there is always something available, the hard part is identifying the brush. I consider brushes pretty much generic like bolts and nuts but a bit more specific.
