SERVICE INFORMATION GENERAL INSTRUCTIONS • Check the ignition system according to the sequence specified in the Troubleshooting. (!1-28) • The ignition system adopts CDI unit and the ignition timing cannot be adjusted. • If the timing is incorrect, inspect the CDI unit and A.C. generator and replace any faulty parts. Inspect the CDI unit with a CDI tester • Loose connector and poor wire connection are the main causes of faulty ignition system. Check each connector before operation. • Use of spark plug with improper heat range is the main cause of poor engine performance. • The inspections in this section are focused on maximum voltage. The inspection of ignition coil resistance is also described in this section. • Inspect the ignition switch according to the continuity table specified in page 20-3. • Inspect the spark plug referring to Section 3. • Remove the A.C. generator and pulser coil referring to Section 10. SPECIFICATIONS Item Standard type Hot type Cold type
TROUBLESHOOTING No spark at plug • Faulty spark plug • Poorly connected, broken or shorted wire • Faulty ignition switch • Faulty ignition coil • Faulty CDI unit • Faulty A.C. generator
Engine starts but turns poorly • Ignition primary circuit —Faulty ignition coil —Poorly connected wire or connector —Poorly contacted ignition switch • Ignition secondary circuit —Faulty ignition coil —Faulty spark plug —Faulty high-tension wire —Poorly insulated plug cap • Improper ignition timing —Faulty A.C. generator —Stator not installed properly —Faulty CDI unit

＊ • Due to the semiconductor in circuit, it
is necessary to use a specified tester for accurate testing. Use of an improper tester in an improper range may give false readings. • Use a Sanwa Electric Tester (073080020000) or Kowa Electric Tester (TH-5H). • In this table, “Needle swings then returns” indicates that there is a charging current applied to a condenser. The needle will then remain at “∞ ” unless the condenser is discharged.
Use the x KW range for the Sanwa Tester. Use the x 100W range for the Kowa Tester. Unit: KW (+)Probe SW EXT (-)Probe
