THIS... EXCEPT REVERSED...........IGN1 is "run" IGN2 is the ballast bypass IGN2 is normally brown but not always. It originally connected to the ballast terminal that feeds the coil+ terminal
IGN1 is ONLY hot in "run" and originally fed the ballast and to the coil, as well as the VR, alternator field, electric choke if used, etc. IT GOES DEAD when cranking
IGN2 is live ONLY in start as is the yellow "start" wire. Start wire feeds the start relay to crank, IGN2 fed full battery voltage to the coil
