Capacitive Discharge Ignition -
C.D.I.
GENERAL
The CDI unit was located on front right of frame,
about the right front shock absorber.
There are three electrical connectors for the CDI:
the two-pin connector and a four-pin connector
on CDI body and a four-pin gear position coupler.
INSPECTION
Disconnect the CDI coupler and connectors and
check each circuit according to the table below:
CIRCUIT COLOR CORRECT
Ignition Puler Bu/Y-G 50-170 Ω
Bl/Y-G 0.1-0.3 Ω
Ignition coil
Bl/Y-Plug cap
w/cap 7.4-11k Ω
w/o cap 3.7-4.5k Ω
Ignition switch
Bl/W-G
No continuity when
switch ON
If the harness and all other components are all
okay, the CDI is probably defective. But before
replace a new one. It’s a good idea to substitute
a known good CDI.
