LouLong, The fuse that keeps blowing is in the BCC. It's F-1, 5amp,named BCC Power. I have a Big Boy battery isolator/relay # 77-90006-120 made by Intellitec. As soon as I install a new 5amp fuse, I hear a clunking noise, I then recheck the fuse only to see that it has blown. I'm very confident that you are going to solve my charging problems. Thanks.
