SW, SX and SY models

8 Remove the fairing (see Chapter 8).

9 Some of the bulbs are accessible with the instrument cluster in place, but access to others requires removing the cluster from the mounting bracket (see illustration 15.9).

10Gently pull the bulbholder out of the back of the instrument casing, then pull the bulb out of the bulbholder (see illustration).

11If the socket contacts are dirty or corroded, scrape them clean and spray with electrical contact cleaner before a new bulb is installed.

12 Carefully push the new bulb into the holder, then push the holder into the casing.

13 Installation of the instrument cluster is the reverse of removal.

18 Ignition (main) switch -

check, removal and installation jji,

Warning: To prevent the risk of short circuits, remove the rider's seat (see Chapter 8) and disconnect the battery negative (■vo) lead before making any ignition (main) switch checks.

Check

1 On R, T, V, W, X and Y models, remove the headlight from its shell (see Section 7). Trace the ignition (main) switch wiring back from the base of the switch and disconnect it at the black 3-pin connector inside the headlight shell.

2 On SW, SX and SY models, remove the fairing (see Chapter 8). Trace the ignition (main) switch wiring back from the base of the switch and disconnect it at the black 3-pin connector.

3 Using an ohmmeter or a continuity tester, check the continuity of the connector terminal

pairs (see the wiring diagrams at the end of this Chapter). Having already disconnected the battery negative (-ve) lead, insert the key in the switch. Continuity should exist between the terminals connected by a solid line on the diagram when the switch is in the indicated position.

4 If the switch fails any of the tests, renew it.

Removal

5 The ignition switch is secured to the top yoke with two Torx bolts (see illustration).To gain access to these bolts, disconnect the ignition wiring connector (see Step 1 or 2), then remove the handlebars and fork top yoke (see Chapter 6).

6 Remove the bolts and withdraw the switch from the top yoke.

Installation

7 Installation is the reverse of removal.
Tighten the Torx bolts to the torque setting
specified at the beginning of this Chapter.
Make sure the wiring is securely connected
and correctly routed.

19 Oil pressure switch - check, §^
removal and installation ^

Check

1 The oil pressure switch is screwed into the crankcase in front of the engine left-hand cover. The oil pressure warning light should come on when the ignition is first turned on, then extinguish once the engine is started. If it does not come on, yet the bulb and fuse (tail light, signal, brake light, horn circuit fuse) are good, pull the rubber boot off the switch and remove the screw securing the wiring connector (seeillustration).

2 With the ignition switched ON, earth (ground) the wire on the crankcase and check to see if the warning light comes on. If the light comes on, the switch is defective and must be renewed.

3 If the warning light comes on whilst the engine is running, yet the oil pressure is known to be good (see Chapter 1), remove the wire from the oil pressure switch with the

engine running. If the light goes out, the switch is defective and must be renewed. If the light remains illuminated, the wire between the switch and instrument cluster must be earthed (grounded) at some point (see the wiring diagrams at the end of this Chapter).

Warning: Avoid working on a hot engine - the exhaust pipes, crankcases and engine oil can cause severe burns. Do not allow exhaust gases to build up in the work area; either perform the check outside or use an exhaust gas extraction system

Removal

4 Pull the rubber boot off the switch and remove the screw securing the wiring connector.

5 Unscrew the oil pressure switch and withdraw it from the crankcase.

Installation

6 Apply a suitable sealant to the upper portion of the switch threads near the switch body, leaving the bottom 3 to 4 mm of thread clean. Install the switch in the crankcase and tighten it to the torque setting specified at the beginning of this Chapter.

7 Attach the wiring connector and secure it with the screw, then fit the rubber boot.

8 Run the engine and check that the warning light operates correctly.

20 Neutral switch - check,

removal and installation ^»

Note:The neutral switch is part of the safety circuit which prevents the engine from starting with the transmission in gear unless the clutch lever is pulled in and the sidestand is up, and prevents the engine from running with the sidestand down unless the transmission is in neutral. An apparent fault with the switch may be due to a defective diode (see Section 23).

Check

1 The neutral switch is screwed into the left-hand side of the engine behind the front sprocket cover. To check the switch, first remove the sprocket cover and chain guide (see Chapter 6, Section 14).
