CDI CIRCUIT 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 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 KΩ range for the Sanwa Tester.
Use the x 100Ω range for the Kowa Tester.
