Installing battery after winter storage
I went to pick up our 2013 240re from storage this week, with the freshly charged battery. When I went to hook up the battery I forgot how I disconnected the cables, there is black and white cables, I'm embarrassed to say but, I assumed back was negative, so, white must be positive. Wrong, it worked, somewhat, but the electric tongue jack seemed to work backwards. Hmmm. when I got home there was no inside power, I discovered there is 2 40a fuses that blow if the battery is hooked up backwards. I replaced them changed the battery leads and things seem OK, except the stereo system in the unit has no sound, the digital display seems dim, I can see radio stations and the volume display shows, but no sound. I pulled the unit out and checked the 15a in line fuse but its OK.
I'm going to the dealer at the end of May, just thought there was something I could do myself.
Could hooking up the battery leads up wrong fry the stereo?
Thanks for listening.
