When i turn on my lights, it acts like my kill switch. The atv shuts off just like it does when i use the kill switch. I havent messed with anything being i was on vacation all last week. Wondering if there is a sensor or something that might have gone bad. Thanks..

 

Not sure what atv you have......but most likely, in the light/kill swith "module" on the handlebars, or down on the electrical pannel, under the hood, there must be a loose wire that is grounding it out. Just check you connections, and clean them too.....
