INSPECTION
SPARK PLUG
Check plug gap using a plug gap gauge and adjust if it is not as
specified.
Standard value: 1.0 - 1.1 mm (.040 - .043 in.)
SPARK PLUG CABLE
(I) Check cap and coating for cracks.
(2) Measure resistance.
Limit: Max. 22 kti
IGNITION, POWER TRANSISTOR
NOTE
An analog-type circuit tester should be used.
(I) Connect the negative (-) terminal of the 1.5V power supply
to terminal @ of the ignition power transistor; then check
whether there is continuity between terminal @ and
terminal @ when terminal @and the positive (+) terminal
are connected and disconnected.
NOTE
Connect the (-) probe of the circuit tester to terminal 0.
Terminal 1 and (+) terminal Terminal 3 and terminal 2

IGNITION COIL
Primary Coil Resistance
Measure the resistance of the positive (+) terminal and
negative (-) terminal of the ignition coil.
Standard value: 0.72 - 0.88 IR
Secondary Coil Resistance
Measure the resistance of the positive (+) terminal and the
high-voltage terminal.
Standard value: 10.29 - 13.92 kR
