Ignition module – testing
If there is a fault in the ignition system the ignition
module must be tested before the ignition system
is removed.
Test the ignition module as follows:
• Connect a test spark plug 502 71 13-01 to the
ignition lead and clip the test spark plug onto the
cylinder.
• Turn the engine over using the starter cord.
• If the test spark plug produces a spark the
ignition module is OK.
