CLUTCH SWITCH
Clutch Switch Function
When the clutch lever is released, the clutch
switch is held in the open position by the lever.
When the lever is pulled in to disengage the
clutch, the switch is allowed to close. This sig-
nals the ECM that the clutch is disengaged and
allows the driver to start the engine when the
transmission is in gear.
If the clutch lever free play is not adjusted properly,
the clutch switch may be released to the closed
position, allowing the engine to be cranked in gear
with the clutch engaged. Refer to the
CLUTCH
section for lever free play adjustment.
Clutch Switch Continuity Test
Remove front body assembly, refer to
BODY
sec-
tion.
Disconnect the two clutch switch connectors.

Set multimeter to
selection.
Connect the multimeter between the two clutch
switch connectors (steering side) and measure
the resistance as follows:
CLUTCH SWITCH CONTINUITY TEST
Clutch lever released
OL (infinite
)
Clutch lever held in
Close to 0
If you do not measure OL (infinite
) with clutch
lever released, check the clutch lever free play be-
fore assuming switch is at fault.
If you do not measure close to 0
with clutch
lever held in, replace clutch switch.
NOTE:
If resistance reading is erratic, switch con-
tacts may be oxidized or corroded due to moisture
ingress, or burned and pitted. Replace switch.
Clutch Switch Replacement
Pull back switch lever rubber protector to access
the switch locking tab.
Using a small screwdriver, compress the switch
locking tab as you pull the switch out of the lever
housing.
