17. IGNITION SYSTEM Bet & Win 250 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.

(!2-4) Disconnect the A.C. generator connector. Measure the exciter coil resistance between the black/red wire terminal and ground. Black/red_ Ground 50_ A.C. Generator Connector 250W ＊ Measure the resistance in the XW range. For A.C. generator removal/installation, refer to pages 10-3 and 10-6.

17. IGNITION SYSTEM Bet & Win 250 CDI UNIT RESISTANCE INSPECTION Measure the resistance between the terminals. Replace the CDI unit if the readings are not within the specifications in the table below. ＊ • 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).
