Onan Q4000 genset problem

Took it to Cummins/Onan in Orlando. They found it to be a bad bearing on the winding shaft. They had to completely tear the unit apart. They were good to me and did it under warrantee. It would have been $1100. Got it back and first time out it quit after exactly one hour of work. Took it back and the fuel pump was bad. They replaced the pump and filter. $349. I haven't taken the RV out since then. Just bought an extended warrantee from Good Sams. It will probably come in handy. Jim

.Bill, I found a circuit board on ebay for $325 from a dealer out West. Didn't need it and they took it back!
