Appreciate your postback and additional information.The initial proposed solution is for a non-CDI version. For a CDI versions, the black/white is the engine cutoff; for the engine to run it should not be connected to anything. The other wire of the CDI goes to the ignition coil. The 3 wires from the magneto going to the CDI are for the exciter and the pulser coils with a ground wire. Both of the active wires from the magneto would have pulsating ACvoltage when starting or engine running; 1 would be ~ 0.5VAC (pulser) and the other considerably higher (exciter).Benimur40032.0125846412
