I need help I was blowing snow the other night there was a smell in the tractor and when I shut it off and went to start it the oil pressure light will come on but the electrical charge light will not come on when I try to start it it wont turn over we checked all the switches with a jumper wire nothing worked we could start it by jumping the starter but would not start with the key so we put a jumper wire on the controller switch under the shroud of steering wheel and it will start with the keys but it bypasses all the safety switches and the electrical charge light still wont come on any one with any ideas
