Re: 70 Force No spark?
Possibly the key switch, check for continuity between the two terminals labeled "M" on the back of the switch. Check it with the key off (continuity) , and on ( no continuity).<br /><br />If box is new and functional, and kill switch is in the run position, I would then check the rectifier, stator, and the trigger for a signal.<br /><br />A Clymer repair manual outlines the test procedures pretty well.
