IGNITION SYSTEM

Warning! Exercise extreme caution
when carrying out maintenance and
repair work on the ignition system.
The high voltages which occur can
cause serious or even fatal
accidents!
Troubleshooting on the ignition
system should always begin at the
spark plug. See "General Servicing,
Troubleshooting" handbook.
Note: The electronic (breakerless)
ignition system basically consists of an
ignition module (1) and flywheel (2).
