Onan GenSet Problems
So, going back to Columbus Day weekend last October, we dry camp in Ellicottville NY for their OctoberFest. First morning turn on generator and one side of coach does not have power, coffee pot side! Check out breakers and everything I can think of. Try turning on and off a couple of times and alas! we got full power. Dismiss it as a very damp morning and we were parked in a grass parking lot. Fast forward to spring and getting the rig ready for another soon to be great camping season. Start the genny to warm up to change the oil and filter and remember the October problem. Try same side of rig (coffee pot side) no power. Dang! Well change oil and I'll poke around some more when I get her home. Couple days later decide to start genny and see if my limited abilities can find out what wrong. Now whole genset won't start! I'm thinking maybe I got a bad ground. Clean ground wire where grounded and off of genset, spray WD40 into all plug in connectors, NOTHING! Was planning to take the RV in for coolant change and routine maintance anyways so make appointment and add generator check out too. Couple of days in the shop and the master mechanic gives me a call. Must be a salesman part time cause he gave me the good news first, coolant flush and fill, dash AC blows at 38 degrees, belts and hoses good etc.. About the generator, well check out all wiring and connections including converter etc. and can't find the problem. Next is to drop the unit from the RV to get at back side of power junction box and the rest of genset. Ok, go ahead what am I to do? Couple of days later again, still can't find exact problem but we know what caused it....MICE made a nice home of my generator! Packed full of mice "insulation" nesting. Well after 3 weeks in the shop they finally found a chewed through wire on the back side of the power box, where the wires come into the junction box.! Repair bill $988.30
Moral of the Story: Careful where you store them over the winter/off season months, I know I'll be looking for a new winter home to store mine!
