Checking ignition spark
Dismantle the plug and clean it from soot
by means of a wire brush.
Check the electrode gap. It should be 0.5
mm (.020 in).
Adjust the gap to the correct distance with
the side electrode.
If the electrodes are worn down more
than 50% the plug should be replaced.
If the electrodes are worn down more
than 50% the plug should be replaced.
If the gap is too wide this results in strain
on the ignition module and the risk of
short circuiting.
Check if there is a spark by pulling the
engine over with the starter.
Try with test plug No. 502 71 13-01 if
there is no spark.
Check if there is a spark by pulling the
engine over with the starter.
Ground the plug to the cylinder and briskly
pull the starter handle.
Make sure that the stop switch is in the
start position.
There should be a spark between the
electrodes.
If there is no spark try with test plug No.
502 71 13-01!
If there is a spark the fault lies in the plug.
Replace the plug.
502 71 13-01
Try with a new plug.
If there is no spark disconnect the stop
switch wire.
If necessary replace the switch.
Try with a new plug.
If there is still no spark remove the short
circuiting cable from either the ignition
module or the stop switch.
If there is now a spark the fault lies in the
stop switch.
Replace the switch.
