ELECTRICAL SERVICE NOTES TROUBLESHOOTING
Keep the following notes in mind when diagnosing an No Spark, Weak or Intermittent Spark
electrical problem:
• Spark plug gap incorrect
• Refer to wiring diagram for stator and electrical • Fouled spark plug
component resistance specifications. • Faulty spark plug cap or poor connection to high
• When measuring resistance of a component that has a tension lead
resistance value under 10 Ohms, remember to • Related wiring loose, disconnected, shorted or

Connect the leads together and record the resistance. • Engine stop switch or ignition switch faulty
The resistance of the component is equal to tested • TRS switch mis-adjusted or faulty
