Crankshaft Position Sensor Gap
Measure trigger coil gap with a feeler gauge. The gap should be
.059 inch (1.0 mm).
Ignition System Troubleshooting
No Spark, Weak, or Intermittent Spark
• Spark plug gap incorrect
• Fouled spark plug
• Faulty spark plug cap or poor connection to high
tension lead
• Related wiring loose, disconnected, shorted, or
corroded
• Engine Stop switch or ignition switch faulty
• ETC switch mis-adjusted or faulty
• Wire harness or connections wet, corroded
• Poor ignition coil ground (e.g. coil mount loose or
corroded)
• Incorrect wiring (inspect color coding in connectors
etc.)
• Faulty ignition coil winding (measure resistance of
primary and secondary)
• Sheared flywheel key
• Flywheel loose or damaged
• Faulty ECU
CHARGING SYSTEM
Current Draw - Key Off
Connect an ammeter in series with the negative battery cable.
Check for current draw with the key off. If the draw is excessive,
loads should be disconnected from the system one by one until
the draw is eliminated. Check component wiring as well as the
component for partial shorts to ground to eliminate the draw.
Crankshaft Position Sensor Gap:
.059" .010 inch
(1.0  .26 mm)
CAUTION
Do not connect or disconnect the battery cable or
ammeter with the engine running. Damage will
occur to electrical components.
