IGNITION SYSTEM INSPECTION
NOTE
•
When there is no spark in the spark plug inspect whether the

each voltage value is normal.
•
Since there are a great many of multimeter brands with dif-
ferent interior resistance the values tested will differ accord-
ingly.
•
Connect the multimeter (1) with a high voltage diverter or an
electric meter with

VOLTAGE OF IGNITION COIL
Replace the spark plug with a good one and connect it with the
engine.
NOTE
Correctly connect each circuit before the test. Normal compres-
sion pressure of the air cylinder is achieved in the test when the
spark plug is installed on the cylinder head.
1. Connect the wire of ignition coil (2) and connect the primary
coil terminal (black / white) with the diverter at the Ground.
2. Press the startup electrical machinery or step on the actuating
lever to measure the primary peak voltage of the ignition coil.
Standard value: 95 V or above
