6.3 Ignition system inspection
*Note
•When there is no spark in the spark plug， inspect
whether the wire or part is loosen or in poor contact and
confirm whether each voltage value is normal.
•Since there are a great many of avometer brands with
different interior resistance, the values tested will differ
accordingly.
Connect the avometer with a high voltage diverter or an
electric meter with input resistance above 10MΩ10CV.
6.3.1 Primary 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 compression pressure of the air cylinder is
achieved in the test when the spark plug is installed on the
cylinder head.
Remove the middle cover.
Connect the wire of ignition coil and connect the primary
coil terminal（black / white） with the diverter at the
Ground. Press the startup electrical machinery or step on
the actuating lever to measure the primary peak voltage of
the ignition coil. Minimum voltage：95V or above.
*Note
The metal area of the avometer prod mustn't be touched
by fingers to prevent electroshock.
6.3.2 Charge coil
*Note
Install the spark plug on the air cylinder head and inspect
with normal compression pressure.
Remove the 4P and 2P joint of CDI group, and connect a
High Voltage diverter between the charge coil of the 2P
joint （red / white terminal）to the wire and the 4P joint
（black terminal）. Press the startup motor or step on the
actuating lever to measure the peak voltage of the charge
coil.
Connecting method: positive pole connected with red /
white line, and negative pole connected with black line.
