Battery cables hooked backwards-opps

[thetanman1957]

Went to get trailer out of storage and when I reinstalled the battery I got the cables hooked up backwards Caught it within a few minutes and made the change. Had a cpl of the 15 amp fuses blown in the panel box, replaced them. Some of the ceiling touch ring type lights are not working correctly now. One stays on all the time,another will not come on and one is very dimly on. Any help would be appreciated. This is on Cougar 2017 327 RLK.

Should be two 30 or 40 amp fuses on the converter... they are for reversed polarity... most likely blown.. they'll usually be off by themselves.. or even on back of the converter..

I did the same thing on a new camper many years ago. Thank goodness I didn't do any damage but a couple of blown fuses. Every camper I have had since I put red tape on the positive cable just to make sure I don't cross them up again.
