Since Cummins owns Onan, would a Cummins service center be able to help you?

Good luck!

Are you sure you have the right part number or was it superseded by another number? I would check back with a onam dealer.

Thanks for the replies  Coach has been at Cummings in Tampa since Jan 19th.  That is the part number that is on my estimate.
Coach was taken in for another problem with Gen  It would cut off after 25/30 mins like it was hot but engine was not hot,  Had the belt, thermostat, and heat sender changed did not solv problem  Took it to Cummings they diagnosed it as needing new PCB
(1400.00) in that process they said brushes were within tolerances but barley.  So i made decision to change Brush Bloch While
it was there.  Was told there was none available in the Cummings system they would have to order thru their national parts dept.
Just thought someone might have had same problem  I have told them to put old brushes back and install new PCB just hope this solves the original problem.(2600.00) OUCH
Thanks for the FORUM.
