Have a short in circuit that powers furnace/monitor panel. These 2 are on same 20 ampere fuse. This started last time I had the trailer on road. Have basic knowledge of electricity and DC current, also have repair manual for this unit. Can change out fuse, sometimes it blows asap, sometimes I can leave it overnite before it blows. I disconnected hot wire from furnace and monitor panel worked fine. Next am, had a blowed fuse. Am at wits end, any help would be appreciated. I have tightened all electrical connections in fuse box.
