Took the MH in to a certified generac dealer this morning. They found some wires that were too close to the flywheel, one of them was cut. They fixed that, but to get to it they had to pull the panel that has all the buttons and oil fill and dipstick are on. Then as he was about to remove the coolant tank he found that the tubing that feeds the radiator when needed was kinked and that for some reason was not down completely in the plastic tank. After fixing both problems, we fired the genny up and let it run for about 20 mins. No problem, then we turned both a/c's and again NO PROBLEM. Total cost with these guys was $143.78. In a few mins I'm going to take the MH out on the freeway for a test while driving. Keep your fingers crossed.
