RV Repair: 12v charging

Question
hello

I have a 2006 fleetwood pioneer tt i accendently crossed the wires on my battery. I recrossed them to norm the only thing that i found was a 3 amp fuse that blew at my radio everything elese seemed to be ok at the converter all fuses and breakers were ok checked with a test light..When i went camping i use a portable honda generator and it was not charging my battery while plugged in but my truck will charge it while running..

Answer
Did you check the 30 or 40 amp atc fuses in the house fuse box they are usually green or yellow.
that would be one spot. the outer is where the battery is located sometimes there is a little black box or gray box that is connected by a wire off the battery and usually has a 2 threaded post on it and sometime there is a little and I do mean little button on the side of it it may bee tripped

Try those things and let me know


Thanks and Have A Great Day
