I have a 2006 Diplomat. The original stereo worked just fine. When I put the coach in storage I turned off the coach and house batteries. I got the coach out of storage this past weekend and when I turned the power back onto the coach my radio would not work. I checked the fuse in the fuse panel and it was blown. I replaced the fuse and it blew again. I wanted to upgrade my stereo anyways so I purchased a new stereo and installed it. I replaced the blown fuse and it blew again. Not sure where to go from here, There must be a loose ground somewhere. I was told to find another positive wire under the dash and splice into that. Has anyone else had something similar or any other advice? Thanks inm advance.
