Headlight not turning off after powering down

I replaced my battery and foolishly put in the battery backwards. When I went to attach the negative (which was actually the positive) terminal the horn sounded. I realized something was wrong and saw my mistake. I put the battery in correctly but now when I power down the bike my headlight doesn’t turn off. Any suggestions?

You’re not alone, there’s been a couple of other posts from owners who’ve done the same thing…

Oof. Reverse polarity strikes again. Sounds like you may’ve fried a relay or ZFE module.
