Onan 10KW Error Code 45

This morning our genset shut down giving us the "service error code: 45", which indicates speed sense lost. About 6 months ago we had this error code show up. I researched IRV2 and found a post that suggested that the connector to control board might be the source of the problem. Followed the suggested action, pulled the connector cleaned with contact cleaner, applies a little dielectric grease and reassembled. The genset has run well until this AM.

We happen to be at the Cummins Service Center in Williston ND, getting some minor services; their generator specialist suggests that the brushes may need to be serviced or replaced. Our genset only has 1870 hours of service. Does this sound reasonable that our brushes could be worn in that little time. The Onan repair manual suggests that the probable fault is the control board. If that is the case I can easily replace the control board, but the brushes may be another issue entirely. Can they be accessed with the genset still in the coach, or must the genset be removed?

Again I appreciate the expertise that is so freely shared on this forum

Brushes are cheap and worth the try. If your gen is on a slide, easy to change. I had a brush that was broken and intermittently lost contact causing shut down. Be sure they clean the armature at the same time, just a cleaning stick applied while it's turning over. Act like you you know about this stuff and maybe they won't "stick" it to you.
Happy Trails,
