Drambo

I think we've solved the problem. Upon arrival at the Millennium factory, they removed the tow bar from the Marathon to install it on the new coach and when wiring everything up, they found a total mess of wiring on the Lincoln. Wires which were to go to the battery were not hooked up properly. They started from scratch and now all of our lights are working properly for the first time. On the way down we discovered if we put the vehicle in "park" and disconnected the power cord, the battery held its charge. I think putting the transmission into park is the key and this is what we'll do in the future.

We bought a 2012 Lincoln MKX last year when we bought a new Marathon XL4s. It has been nothing but frustration. We've had the factory look at it as well as four Ford dealers. It is a keyless system also. The book says to put it in neutral, hit the button to turn the car off and then hit the button twice until you see "accessory mode active". We've done that as well as make sure the radio and climate controls are off. We still have a dead battery unless we start it every 3 hours. We've even disconnected the power cord from the coach in case it's the bus. Still had a dead battery. It doesn't have an independent braking system and I use a Blue Ox towing bar. When we bought the car, we had an RV dealer put the necessary wiring on it to keep it charging while driving down the road. I'm about ready to get another vehicle!!
