Xplorer 300 4×4 transmission working backwards

This might seem very weird but I’m hoping someone has ran into this problem before.. I have a 99 xplorer 300 that I just replaced the stator on…everything worked fine before replacing it minus the fact that the battery was not charging.

After putting everything back together and starting the motor I put the gear selector into high gear and pressed the gas….the ATV moved backwards… So I then put it in reverse and it moved forward…. Totally stumped on this never seen it before.

I have been told by some the the polarity might be reversed some how???
