SECONDARY COIL CHECK
NOTE
It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary
coil circuit of this ignition coil. So, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug
to the ignition coil.
3. Connect the ignition coil connector.
4. Earth the side electrode of the spark plug and crank
