UPDATE - onan 5500 diesel generator will not stay running

Update on my friends generator.

She just got a call from the Cummins shop. Unfortunately not a simple fix.

The brushes were toasted, causing major damage to the stator and rotor. Total repair cost $4500 CAN funds. They said it may have been a servicing issue. Brushes need to be check/replaced when oil is changed. They also said the hour meter was disconnected, maybe by the previous owner so the 127 hours was not correct. She has never noticed that is was not moving.
