I recently purchased a 2006 Fleetwood Excursion and now I'm experiencing problems with the DC voltage in my coach. The coach is connected to 50 amp shore power. For starters the steps no longer extend when opening the door, the internal upper part of the control panel that monitors the fresh, grey, black water and other functions including main and aux batteries are unlit. The monitor below that is lit and displays battery state full, AC in is lit, charge DC volts 13.5 volts, Invert DC amps <10, incoming AC breaker 50 amps. The coach has 2-12v chassis batteries and 4-6v house batteries. I tested all the batteries with a multimeter, the house batteries tested just over 6 volts, the chassis batteries tested with almost no voltage. I tried to hook up a trickle charger to the 12-volt batteries, but the charger kept on saying hook the leads to the battery posts and didn't even recognize them as batteries. I was under the impression that shore power was supposed to provide 50 amps to the inverter/charger which then charged all the batteries.
Please offer any assistance as I'm new to RV's and learning how the whole electrical system works.
