3.7.3 CDI INSPECTION
Disconnect the CDI module from the wire
harness
Test resistance of the terminals with an
multi-meter.
● Since there is semiconductor in return circuit,
testing result may be significantly different if
different multi-meter are used.
● If the pointer on the dial flickers and finally
stops at ∞in testing, it should be regarded as
normal. Because the capacitor in the CDI
module is charged while being tested and it
cannot discharge at this time.
