6.2.6 To examine the ignition cable
1. Pull up the rubber seal by the ignition unit and
remove the ignition cable.
2. Put a pair of pointed pliers in the spark plug
connection and pull out the spring and cable end.

be made shorter. Make a new hole in the cable and
attach the connection spring.
4. The connection in the illustration can be used to
make sure that the ignition cable is not broken. The

6.2.7 To examine the short circuit cable and the
stop switch
1. Remove the starter and the short circuit cable on the
ignition unit.
2. Put back the starter and check if the spark plug
makes a spark.
3. Examine the short circuit cable.
a) Use an instrument or a battery in series with a
test lamp.

body.
The lamp must not come on when the switch is in
operation mode.
If the lamp comes on, first examine the insulation on the
cable.
If the cable is not damaged, examine the stop switch. If
the cable and the stop switch are in working order,
replace the ignition unit.
