SUMMARY TABLE
Test to perform Ignition coil output Tester wires Component wires Test adapter on MAG spark plug cable Engine ground WHITEBLUE wire (+) of ignition coil BLACK wire (-) of ignition coil BLACKRED wire of magneto harness BLACK wire of magneto harness YELLOW wire of magneto harness YELLOW wire of magneto harness Switch Dial
RESISTANCE MEASUREMENTS
As an alternate method, magneto system components can be checked with digital ohmmeterNOTEAll resistance measurements must be performed with parts at room temperature (approx20C (68F))Temperature greatly affects resistance measurementsDisconnect connectors at ignition coil and magneto junctionMeasure resistance between each terminalRefer to the following table for values and wire colorsNOTEAn ignition coil with good resistance measurement can still be faultyVoltage leak can occur at high voltage level which is not detectable with an ohmmeter'
