Note:
The ignition lead is molded to the
module.
Accurate testing of the ignition
module is only possible with special
test equipment. For this reason it is
only necessary to carry out a spark
test in the workshop. 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 not adjustable.
Since there is no mechanical wear
in these systems, ignition timing
cannot get out of adjustment.
However, an internal fault in the
circuit can alter the switching point
in such a way that a spark test will
still show the system to be in order
although timing is outside the
permissible tolerance. This will
impair engine starting and running
behavior.
