All it is is an active circuit ground wire that is grounding the coil to the
block keeping the coil dead ,disconnect it ,an the engine should fire ,
but you wont have a fail safe!..:thumbs-up:
Not sure what radio set up you have ,but some do have a fail safe an that may have an on
board kill switch that can be remotely kill the engine in case of an emergency!
If you want to test ,just simply pull the spark plug an plug the coil wire back on an hold
the plug against the block an give...
