Just got a call from Smith Powersports in Bellflower, CA. They're Onan gennie specialists and have some videos showing Onan service and maintenance.
I took my coach there Wednesday and they gave me an update last night, said it was showing perfect on the meter and transfer switch. I told him I heard the transfer switch clicking after I smacked a few good one. It would switch after about 90 seconds and was buzzing which led to his diagnosis.
So $500.00 and change and I'll be good to go with a new transfer switch.
I also inquired about a remote generator start switch at my bedside. He said he can put as many remote start switches anywhere I wanted. I'm so pleased with these guys and I've been looking for someone close to Long Beach that does respectable, quality RV service.
