I have a 02 big bear 400. It will run if I pull start it but it won't start by the button. Also when I turn the key on instead of nuetral light coming on I get the red oil temp light. When I do have it running by pulling it the key will turn it off. I thought the battery but I have it hooked up to a battery charger still nothing, and I've put a differnt push button set up on it and still didn't work and still no nuetral light just oil temp. ?????
