IGNITION COIL (WITH BUILT-IN POWER
TRANSISTOR) CHECK
Check by the following procedure, and replace if there is
a malfunction.
SECONDARY COIL RESISTANCE CHECK
Measure the resistance between the high-voltage terminals
of the ignition coil.
Standard value: 8.5 - 11.5 kΩ
PRIMARY COIL AND POWER TRANSISTOR
CONTINUITY CHECK
NOTE
1. An analogue-type circuit tester should be used.
2. Connect the negative ( - ) prove of the circuit tester to
terminal 1.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning and power
transistor from breakage.
1.5V power across 2 - 3
When energized
When not energized

RESISTIVE CORD CHECK

Measure the resistance of the all spark plug cables.
1. Check cap and coating for cracks.
2. Measure resistance.
Limit: Max. 22 kΩ
Ignition System
Continuity across 1 - 2
Yes
