Paul, make sure the green light is blinking on the inverter remote, that indicates charging, on ours. When we purchased our 1997 Royale ( used ) we couldnt keep the house batterys charged. Long, long story, but after the pros couldnt find the problem I discovered a 2/0 cable in the electrical/battery bay had never been crimped from the factory. I had my hand checking for a warm wire and discovered it. Removed the schrink tubing and the lug fell off. Lots of fretting and heat over the years. New lug and crimp and things are working fine. I BET IT DROVE THE PREVIOUS OWNERS NUTS. Invest in an laser thermo gun, my Raytek costs $75.00. Check wires, tires, bearings, exhaust, etc. ED
