    Hey, have an LC4 with SEM ignition and an odd issue that has me stumped. Bike starts and runs great, but I don't get any lighting/AC voltage output from the stator. Resistance on stator is fine and I also even tried a new stator with same results. Flywheel and magnets look fine also and I even cleaned up the magnets a little with no change. I even tried hooking up a regulator and I don't get any DC voltage either. Anyone have a clue what else to check? I attached pic of flywheel in case anyone can spot something.

    False alarm :D user error...i measured AC output wrong by measuring yellow to ground. Measuring between yellow wires shows good voltage.
