Default Re: G21A has NO spark

Not 100% sure but I don't think so. I think it is the type of ignition that has the electronics all tied up within the coil and laminations. Magnets in the flywheel cause the coil to give a spark every revolution. There is one wire coming from the coil and that is the stop wire. Like I said in my previous post, not sure if "stop" has this wire grounded or ungrounded. The wire goes to the "stop" relay and the stop relay then either grounds or ungrounds it (not sure which) when you let off the gas. Need someone to chime in here for more help. - RAY
