taillight

Just got home from a day of riding and now my headlight and tail light won't shut off. They key is removed from the ignition and the E stop is down. Any ideas? Thanks

Comes and goes, kills my display too. It started happening after I tipped the sled last week. Haven't found any shorts. Checked every connector except the ones below/behind engine that are hard to reach. I don't have heated shield acc. I suspect oil got into the engine connectors... Ideas?
