the owner shorted out some wires we fixed them at one time I was getting a spark. now I'm not. what I need to know is how the system works. how the modual interaks with the magneto. or if some one has a manual or a web sit I can go to
if it is a newer model engine the hot wire running from the switch has a resister on some model's. that could be 1 problem. also check the regulator for it's output(should be 14-16 volts, if i remember correctly). if niether of those, i would have to go back to the book's to make sure.
