IGNITION TESTS
Igniter Unit
Resistance Test
Remove the spark plug cap from the high-tension
cord.
Connect Ohmmeter test probes to igniter unit coils
as shown:
Igniter unit coil resistance:
• Primary coil resistance: 0.5 to 0.9 kΩ
• Secondary coil resistance: 10 to 16 kΩ
If measurement is out of specification, replace the
igniter unit.
Spark Plug Cap
Resistance Test
Measure spark plug cap resistance.
Spark plug cap resistance:
• 8 to 12 kΩ
If measurement is out of specification, replace the
spark plug cap.
Engine Stop Switch
Check continuity of the emergency stop switch:
If the result is out of specification, replace the
emergency stop switch.
