Ignition system and heated handles
8.1.2 Do a check of the stop switch if there
is no spark
If there still is no spark after you replace the spark plug,
remove the short-circuit cable from the stop switch. See
figure 4.
The stop switch can be easily detached with a
screwdriver.
Use a screwdriver pinch the snap fastener of the switch
inside the throttle.
CAUTION: The stop switch has a non
locking design and must be replaced with
the same type of stop switch.
If the plug now sparks, the fault is either in the stop
switch or the short-circuit cable.
Change the switch as needed and inspect the cable
insulation for damage.
8.1.3 What to do if there still is no spark
• Inspect other cables and connections for poor
contacts (dirt, corrosion, cable breakage and
damaged insulation).
• Make sure that the cables are correctly drawn and lie
in the cable grooves. See figure 5.
• Inspect the service connection for AutoTune (Fig. 6)
and the ignition connection (Fig. 7).
• Examine the cables in the throttle. See "5.6
Assembling the finger throttle" on page 16
Tip! Use an Ohmmeter to check if a cable is broken.
