I'm relatively new to maintaining my own RV and have hit a major snag. Last time I went out my generator ran, but there was no power to the coach. When I got home and plugged in, still no AC power to the coach. The 5amp fuse was blown at the relay behind the battery, but no other circut breakers are/were tripped and no other fuses blown. The Micro works, but nothing else. Any suggestions?
