I am working on a buddies 1986 john deere 317 with a kohler kt17.. He said it has not ran in years. I cleaned the points and re-gaped them and still couldn't get any spark so i bypassed the seat switch, still nothing. So I ran a wire from the positive side of the coil to the battery and got it running. I noticed that the coil gets hot even if i am not running it... Is there some type of resistor that I have bypassed?
