hello all i need some help. My son was riding his 2000 king quad 300 and all was well till he turned of the key. He has lost the neutral light and it wont start. the headlights work , winch works, but no neutral light so it wont turn on. can someone please tell me where the safety switch is located so i can check to see if the wire is loose?? also any other ideas of what the problem could be? thank you so much
