Exercise extreme caution when
troubleshooting or carrying out
maintenance and repair work on the
ignition system. The high voltages
that occur can cause serious or
even fatal accidents!
Troubleshooting on the ignition
system should always begin at the
spark plug – b 4.4
The electronic ignition system
basically consists of an ignition
module (1) and flywheel (2).

The ignition module accommodates
all the components required to
control ignition timing. There are
two electrical connections on the
coil body:
: High voltage output (1) for
ignition lead

: Connector tag (2) for short
circuit wire
Testing in the workshop is limited to
a spark test. A new ignition module
must be installed if no ignition spark
is obtained (after checking that
wiring and stop switch are in good
condition).
Ignition timing is fixed and cannot
be adjusted during repair work.
Since there is no mechanical wear
in these systems, ignition timing
cannot get out of adjustment.
