Generator not starting

Hello,
We purchased a 2007 Winnebago Class A recently. I started the generator every 3 weeks in the Winter, and it ran fine. Tried to start it yesterday, and there was just a loud clicking coming from the generator. All batteries are charged, so could it be the starter or solenoid issue ? It's a Onan 5,500 Marquis Gold. Since we are newbies, any help would be greatly appreciated. Thank you !!

    Google "Flight Systems Onan generator troubleshooting guide" and download a copy. It's the best troubleshooting guide that I've seen. Also contact your Cummins/Onan dealer and get a copy of the Onan Marquis Service manual. The Onan manuals are excellent. Hard to know what your problem is just based on your description. Did you try both the inside switch and the switch on the generator?After you follow rk911's advice, grab a multimeter and start going through the Flight Systems guide.
