I am trying to get just a wiring diagram for a 2002 harely davidson sportster 1200 custom to figure out why i keep berning out the coils.
This is strange. I've been working on Harley's for almost 40 years and I've only run into two bad coils on the later model bikes. Are you using original equipment coils? If so, are you using the correct ones?
Coils come in different varieties for different uses. There are coils made for racing, road use, electronic ignitions, and points type ignitions. The coil you want is for road use with electronic ignition. If you use a digital volt ohm meter and test the resistance of the primary winding of the coil, it should check out at between 3 and 4 ohms. The "primary" winding is the coil of wire inside the coil that goes from one small terminal to the next. Put your DVOM leads on the small terminals, one lead on each terminal, with the meter in "R x 1" position. It should read between 3 and 4 ohms.
Did you find out what the issue was with burning out could on your sporty?
