My wife and I are on a trip from Nashville to Seattle in our “06 Thunder, not the best time of the year for a trip across the northern states, but trying to get to Seattle to visit ailing relatives. While driving across Montana yesterday, west bound on I90, I noticed that the Aladdin system indicated the battery charge was decreasing rather fast and I noted the volt meter indicated almost no charge. A short while later, the “check engine” light came on followed by the “check tran” light. Fortunately, we were approaching a truck pull-off area which I took. Shortly after coming to a stop, putting the coach in neutral, the Aladdin system shut down, the transmission indicator went blank and the engine shut down. I inspected the engine and saw nothing out of the ordinary. Called for a tow and transported the coach back to Butte MT, about 15 miles back on I90. The service shop, Baker Towing and Truck Repair, diagnosed the problem today as a bad alternator, replacement cost of about $1,500. No unit in the area and the shop is having one shipped overnight and will replace it tomorrow. We plan to get to Missoula once the coach is back running and then we will stay there until we have a good weather window to continue to Seattle. I called Beaver Coach Sales Service and was told that the coach responded as expected with a severe low voltage condition. I’m surprised that we lost the alternator and at the cost. Fortunately we have an extended warranty which is covering most of the cost.
