module must be tested before the ignition system
is dismantled.
Check the ignition module as follows:
• Unscrew the spark plug. Fit the 507 71 13-01
spark plug to the ignition cable and connect
the cabling used to test the 577 83 18-01 igni-
tion module as outlined in Figure 10.
• Turn over the engine with the starter cord.
• If a spark appears on the test spark plug, the
ignition module is not faulty.
