STARTER/IGNITION INTERLOCK

7.11

GENERAL

The starter/ignition interlock system is designed to prevent
unintended start-up and/or forward motion of the motorcycle.
One of three conditions must exist to allow operation of the
vehicle:

●

Clutch disengaged (lever pulled in)

●

Transmission in Neutral

●

Sidestand retracted

Starter Circuit

The starter circuit prevents the motorcycle from being started
unless a ground has been established at the starter relay.
This ground comes from one source.

●

By disengaging the clutch (pulling in the clutch lever) and
grounding through the clutch lever switch.

Once the starter circuit is grounded and the starter button
pushed, the starter relay can be energized. The energized
relay then allows the starter motor to crank the engine.

Ignition Circuit

The ignition circuit prevents the motorcycle from operating
unless a ground is established at the system relay. If this
ground is not established, the ignition system will not be
turned on and the motorcycle will not run. Grounds may be
established three ways.

●

By retracting the side stand and grounding through the

side stand switch

. See Ignition Test 1 on following page

to check sidestand switch function.

●

By placing the motorcycle in neutral and grounding
through the 

neutral switch

. See Ignition Test 2 on fol-

lowing page to check neutral switch function.

●

By disengaging the clutch and grounding through the

clutch lever switch

. See Ignition Test 3 on page 7-28 to

check clutch switch function.

Note that the ignition circuit is enabled when the transmission
is in gear with the side stand extended if the clutch is disen-
gaged (clutch lever pulled in). However, if the motorcycle is in
gear with the side stand extended, and the clutch lever is
released, the ignition ground is lost and the ignition system is
turned off. This system will prevent vehicle operation if for-
ward motion is attempted with the side stand down.

See Ignition Tests on following pages.

Use harness connector adaptor kit (HD-41404) gray
male probe and patch cord.
