As an alternate method, magneto system components can be checked with digital ohmmeterN E: All resistance measurements must be performed with parts at room temperature (borax20C (68F))Temperature greatly affects resistance measurementsPART NAME ET Trigger coil Ignition generator coil Low speed High speed IG NITIO OIL Primary winding Secondary winding (spark plug cap remove) Insulation
Disconnect connector at ignition coil and magneto junctionMeasure resistance between each terminalRefer to the following table for values and wire colorsN TE: An ignition coil with good resistance measurement can still be faultyVoltage leak can occur at high voltage level which is not detectable with an ohmmeterRESIST CE OHM 190300 4975 2.84.3 0.30.716 (800016000) Display showing zero (0) means short circuitRE ARKS
