Changeover switch not working?

Today I was going to do my routine generator exercising, but I'm now not getting any 110 power from my generator. When I pug into shore power I hear the changeover switch click and everything works, but when I start up the generator I dont hear the switch activate.

My rig is a 1988 Ultrastar by Champion class A with a Onan 4 K generator that is original.

Can someone guide me in the right direction of what to check and look for? Thanks

I am not a pro by any means but I have been thru this. In. My case my transfer switch default position is shore. So I am a little confused as to why you would here a click when plugged into shore. I only hear a click when my genset is running. It could be a wire burnt out from your genset to the transfer switch. Check the voltage on both legs of your generator. There should be a junction box near the generator were you can check the voltage. If you have voltage here then you have eliminated the generator.

I gather you tried it on generator and had no power? Have you reset the circuit breaker on the generator itself? If it is tripped, no power will reach the transfer switch, so it won't "click" over to generator mode either.

My first question would be is: How do you know that the generator is putting out 110 Volts?????? Have you checked the fuses/breakers on the generator? How you taken a volt meter and checked the output of the gennerator????

Ok, I found the problem. The 30 amp main breaker was off. The breaker switch is mounted on the side of this generator so with it not being on the front it wasn't obvious for me to see and anytime there is a problem my first conclusion is always the worse. Thats just the way I am.

My last trip was about 6 weeks ago and was a 5 day boone-docking trip and the gernerator worked fine. Not sure if it tripped on got bumped by something, but everything is fine now. Thanks everyone!
