Guys,

End of last year after I got the Onan finally running nicely and then the Gen decided to give me more troubles but stopping AC output. Understanding that the Bridge Rectifier is the most likely cause I got one and just replaced it this morning. No luck, still no AC output. I took a look at Gene's website and read the post about no AC output and there it is mentioned to check the Flywheel Alternator AC output between terminals 8 & 11 on the Onan board. Voltage should be between 28 and 30 VAC. I checked and I read 22 VAC. Per the post it says "When the Voltage Regulator fails, it can load down this signal to less than 20 volts AC & the control Board will not function".

Could this be the problem? I didn't think the Onan board controlled the GEN output but it is mentioned as a cause for no AC voltage output.

Any suggestions? It's hot one here in INDY and we are planning a day trip tomorrow and would be nice to have the roof air working!

Jon
