Hi, 6mos. ago we bought an 03 predator it runs great. But the problem now is last July we went to St.Anthony dunes and every time you would hit the rear brake the engine would die. I adj. brake light switch and it seemed to cure it. Then I noticed the tailight/brakelight quit, I changed the light and turned on ign. and brake light stays on. I unplugged both brake switches and light still stays on. Also with both switches hooked up and light bulb in if you touch either brake the eng dies. Has anyone had this happen?
