1997 Xplorer 500 battery hooked up incorrectly

Starting off this atv has not been ran for about a year. Went to try and electric start and just had the sound of a week battery, tried charging…battery would not take a charge. tried jumping….would not jump. So decided to replace battery. Bought a new battery and put it in the same way I had the previous one in and didnt even pay attention to the positive and negative which I hooked up incorrectly this time. Anyways get it all hooked up incorrectly and not even still knowing turn the key on and lights go on and everything seems fine. Then go to start it and it sounded wrong…I figured maybe the starter went out so then I just went ahead and pull started it and went on my way for now. Everything seemed to be working just fine. About a mile later after riding through my property the ATV kills and there is no power with key, no lights nothing. I was going hunting so I got off and walked the rest. Come back and still no lights when key goes on. So I pullstart and ride back in, never died on me again but then lights begin to work with charging system on ATV I’m assuming. I noticed when I got to house that I hooked it up incorrectly. I hooked battery up correctly and still nothing is working. When ATV is off I have absolutely no power anywhere. I’m thinking a main fuse or something was blown. My mechanical experience is minimum and this thing is old and not prestine condition. Any pointers on where to look for a fuse or what it could be.

Please and Thank You!
