Disconnect the ignition coil wires and
remove the ignition coil bolt and ignition
coil.
Ignition Coil
INSPECTION
CONTINUITY TEST
The CDI unit is not adjustable. If the
timing is incorrect, inspect the CDI unit,
pulser coil and A.C. generator and
replace any faulty parts.
Measure the resistance between the ignition
coil primary coil terminals.
Resistance:
Mongoose/KXR 90) : 2.22.6/20°C
Mongoose/KXR 50) : 3.715.2/20°C
Measure the secondary coil resistances with
and without the spark plug cap.
Resistances:
(Mongoose/KXR 90)
(with plug cap) : 8.39K/20°C
(without plug cap) : 3.14K/20°C
Mongoose/KXR 50)
(with plug cap) : 8.81K/20°C
(without plug cap) : 3.51K/20°C
Correctly operate the tester following the
manufacturer`s instructions.
Note: The readings in this table are taken
with a YF-3501 Tester.
