Ignitor Power Supply

Turn ignition off. Disconnect harness from ignitor. Turn ignition on. Using voltmeter, check for battery voltage between ground and Black/Yellow wire of harness. If voltage is not present, check for open in Black/Yellow wire between ignition coil and ignitor harness connector. If wire is okay, check ignition coil power source, ignition coil resistance and in-line radio noise condenser (for internal short to ground).
