23 Sidestand switch -
check and replacement
Check
1 The sidestand switch is mounted on the
frame just behind the sidestand (se.
illustration 23.8). The switch is part of the
safety circuit which prevents or stops the
engine running if the transmission is in gear
whilst the sidestand is down, and prevents
the engine from starting if the transmission is
In gear unless the sid.stand is up, and
unless the clutch is pulled in (UK V models
and all US models only - see Section 25).
Before checking the electrical circuit, check
the bulb (see Section 17) and fuse (see
Section 5).
2 Trace the wiring back from the switch to its
connectors behind the left-hand side panel
and cisconnect them (see .I&8htion).
3 Check the operation of the switch using an
ohmmeter or continuity test light. Connect the
met~ to the black/white and green wires on
the switch side of the connector. With the
sidestand up there should be continuity (zero
resistance) between the terminals, and with
the st81d down there should be no con~ity
(Infinite resistance).
4 If the switch does not ~ as expected,
it is defective and must be replaced. Check
first that the fault is not caused by a sticking
switch plunger due to the ingress of road dirt;
spray the switch with a water dispersant
aerosol.
S If the switch is good, check the sidestand
relay and other components in the starter
circuit - described in the relevant sections of
this Chapter. If all components are good,
check the wiring between the various
components (see the wiring diagrams at the
end of this book).

23.8 The sidestand switch is secured by two bolts (arrows)
2 Disconnect the relay wiring connector and
remove the relay from its mounting (He
IIkJSb'atIon). Using an ohmmeter or con~ity
tester, connect the positive (+ve) lead to the
No.1 terminal on the relay and the negative
love) lead to the No.2 terminal on the relay (...
Illustration). There should be no continuity
between these terminals. Using a spare 12 V
battery and a set of insulated jumper leads,
connect the battery positive (+ve) lead to the
No.3 terminal on the relay, and the battery
negative (-ve) lead to the No.4 terminal on the
relay. With the battery connected. there should
be C(X1ti1uIty (zero ie8ist&;-oi») i1dk:at8d on the
ohmmeter on tester. If either of the above
conditions do not exist, replace the relay.
3 If the relay is good, check the other
components in the starter circuit as described
In the relevant sections of this Chapter. If all
components are good, check the wiring
between the various components (see the
wiring diagrams at the end of this book).

4 Remove the right-hand side panel (see
Chapter 7).
5 Disconnect the relay wiring connector and
remove the relay from its mounting (He
Ilkiau..-uu.I 24.2).

Replacement
6 The sidestand switch is mounted on the
frame just behind the sidestand. Trace the
wiring back from the switch to its connectors
behind the left-hand side panel and
cisconnect them (Me IIu8tr8tion 23.2).
7 Work back along the switch wiring, freeing
it from any relevant retaining clips and ties,
noting its correct routing.
8 Unscrew the two bolts securing the switch
to the frame (Me IIkIatration).
9 Fit the new switch to the frame and install
the retaining bolts, tightening them securely.
10 Make sure the wiring is correctly routed
up to the connectors and retained by all the
necessary clips and ties.
11 Reconnect the wiring connectors and
check the operation of the sldestand switch.

24 Sidestand relay -
check and replacement
Check
1 If the switch and wiring are good. the
sidestand relay may be at fault. The relay Is
located behind the right-hand side panel.
