Installing battery after winter storage

[Bilsnhoj]

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.
Any suggestions?
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.
Happy camping.

when in doubt about which wire is pos..and which is neg.. just follow one at a time to see which one attaches to the frame.that one will be neg.
also paint pos wire with red nail polish

try using shrink wrap for color identification, a lot better than nail polish or paint. Any hardware store carries it.

that might be your opinion, but nail polish takes 3 seconds to put on .and no running to the store... more time to have a cold one...lol

I'm pretty sure theirs an inline fuse for the stereo.
