I finally have the problem solved. I took the rig to 3 rv repair places and1 truck repair facility. After hundreds of dollars spent no one could trace or find the problem. With several temporary fixes to operate the vehicle, run the levellers etc. I managed to make it have a vacation and make it home. I took the rig to the local mechanic and within an hour he had located the problem. The ground cable to the battery had corrosion inside the connector. It could not be seen but he was quite sure the problem lay inside . We cut it off and sure enough it was green. It took some work but I did manage to get it well cleaned. We used a different connector and filled the hole where the wire goes in with solder and then stuck the wired in. There will never be corrosion in there again. The ground for the electrical step was also corroded and the step operated intermittently. It is now working again.
