Bought our 2005 Beaver Monterey in late June 2013 and picked it up at Alliance Coach in Florida. When we did our walk through we had problems with generator remaining running when engine was started or running. This was late on a Friday, wife was sick and needed to be back in Reno, NV in 5 days. Mechanic could get them to run together by bypassing the BIRD (I was new to motor homing and in a rush, everything else worked OK). Mechanic said when we get to Reno go to either an Onan or Cummings shop and the warranty would pay for repairs.
We've now had our MH for over 3 years and had the generator serviced by various facilities, all authorized Onan facilities, and each time after one or 2 days operating properly the same things will happen. Either start the generator or start the engine and after 30 seconds the generator will shut down with a 27 code. This happens whether I start the generator at the dash, generator or Xantrex control panel.
Thursday last week we just had it serviced, again, at Alliance Coach and when we left there it was operating properly. When we got down the road about a 100 miles and stopped for fuel in the afternoon I wanted the AC on to cool the coach and the gen and engine would not sync. Yesterday I was trouble shooting the problem and the first time I started the gen at the gen then started engine it synced. Ran it loaded for 5 minutes with both ACs on and electric heater working. Turned everything off and cooled gen down for 5 min. Went inside started eng then gen at the dash and again they synced. Loaded them up again and shut them down. Then after 10 minutes I attempted to start them at the Xantrex control panel and this time they would not sync. I cleared fault codes at both the Xantrex and dash and still could not get them to sync. When I attempted to start them the last time the Alladin Electrical screen was showing that the Auto Transfer switch was attempting to connect to shore power first even though I had disconnected from shore power.
What am I doing wrong or? After several services and multiple techs looking at this problem, and it showing the problem or working properly I'm lost. (I know there goes my man card)
