Section 05 ELECTRICAL SYSTEM Subsection 01 (IGNITION SYSTEM)
IGNITION COIL Primary winding resistance BROWN BLACK and BROWN ORANGE wires 00.2 to 0.5 Disconnect the ignition coil from the ECM Secondary Secondary winding winding resistance spark resistance spark plug wires and plug wires cap included removed Between both spark plug caps Male terminals of coil 9.6 to 14.4 With spark plug wires removed from high voltage coil
IGNITION TIMING
Normally ignition timing adjustment should not be requiredIt has been set at factory and it should remain correctly adjusted since every part is fixed and not adjustableThe only time the ignition timing might have to be changed would be when removing and reinstalling the magneto housing, replacing the crankshaft, the magneto flywheel, the CPS or the ECMIf the ignition timing is found incorrect, first check for proper crankshaft alignmentThis might be the indication of twisted crankshaftRefer to LEAK TEST AND ENGINE DIMENSION MEASUREMENTThe ignition timing can be checked with either the engine hot or coldAlso, the ignition timing is to be checked at 3500 RPM with timing lightNOTE: Between 3000 and 4000 RPM, the spark advance does not changeSo when checking ignition timing at 3500 RPM, change in engine speed within 500 RPM will not affect the timing mark when checked with the timing light
