Electrical system 9 21 Digital trip meter check 59 First check the fusebox fuses see Sec tion 5 On N 1992 models if they are good remove the windshield see Chapter 8 and check the trip meter 5 A fuse located in its own holder just in front of the meter 60 If the fuses are good check the power input to the meter as follows disconnect the trip meter wiring connector see illustration 15 12 Check for battery voltage between the red green wire terminal on the loom side of the connector and a good earth ground with the ignition switch OFF If there is no voltage first check whether you have power to any other components i e lights and if not check the battery its connections the main fuse and the starter relay connections If there is power to other circuits check the red green wiring and connectors for faults referring to the relevant Wiring Diagram at the end of the Chapter If there is voltage check for continuity to earth in the green wire 61 If all is good so far check for battery voltage between the black wire terminal on the loom side of the connector and a good earth ground with the ignition switch ON If there is no voltage check the wiring and connectors for faults referring to the relevant Wiring Diagram at the end of the Chapter If there is voltage the trip meter is probably faulty but it is worth disconnecting then reconnecting the battery positive lead which resets the trip meter to see if this kicks it back into action If not replace the meter with a new one 62 To check the power input to the trip sensor in the speedometer the sensor sends the information to the meter so if the meter is on but does not count properly it could be the sensor that is faulty displace the instrument cluster from its bracket see Section 15 but leave the wiring connectors connected Disconnect the trip sensor wiring connector on the back of the cluster and check for battery voltage between the black wire terminal on the loom side of the connector and a good earth ground with the ignition switch ON If there is no voltage check the wiring and connectors for faults referring to the relevant Wiring Diagram at the end of the Chapter 63 If there is voltage check the sensor output to the trip meter as follows first support the bike using an auxiliary stand so that the front wheel is raised off the ground Disconnect the trip meter wiring connector and connect a voltmeter between the white blue and green black wire terminals on the loom side of the connector With the ignition ON slowly turn the front wheel through one full turn while observing the voltmeter On N 1992 models the meter reading should swing slowly between 0 and 5 V a total of eight times On all other models the meter reading should swing slowly between 0 and 0 6 V a total of twelve times If there is no reading or the reading is incorrect check the wiring and connectors between the 17 2a Carefully pull the bulbholder out of the instrument cluster meter and the sensor If that is good replace the speedometer with a new one the sensor is faulty but is not available separately from the meter If the reading is good the trip meter is probably faulty but it is worth disconnecting then reconnecting the battery positive lead which resets the trip meter to see if this kicks it back into action If not replace the meter with a new one Digital trip meter replacement 64 Remove the meter see Section 15 and replace the whole thing with a new one individual components are not available 17 Instrument and warning light bulbs replacement 1 Remove the fairing see Chapter 8 Many of the bulbs are accessible with the instrument cluster in place If access is restricted displace the cluster from the bracket see Section 15 2 Carefully pull the bulbholder out of the instrument cluster then pull the bulb out of the bulbholder see illustrations If the socket contacts are dirty or corroded scrape them clean and spray with electrical contact cleaner before a new bulb is installed Make sure the new bulb is of the correct wattage see Specifications Carefully fit the new bulb into the holder then fit the holder Into the housing 3 Install the instrument cluster and or fairing as required see Chapter 8 17 2b then pull the bulb out of the holder 18 Oil pressure switch check removal and installation Check 1 The oil pressure warning light should come on when the ignition main switch is turned ON and extinguish a few seconds after the engine is started If the oil pressure warning light comes on whilst the engine is running stop the engine immediately and carry out an oil level check and if the level is correct an oil pressure check see Chapter 1 2 If the oil pressure warning light does not come on when the ignition is turned on check the bulb see Section 17 and fuse see Section 5 3 The oil pressure switch is screwed into the crankcase on the left hand side Remove the belly pan see Chapter 8 and the front sprocket cover see Chapter 6 for access Pull the rubber cover off the switch and remove the screw securing the wiring connector see illustration With the ignition switched ON earth ground the wire on the crankcase and check that the warning light comes on If the light comes on the switch is defective and must be replaced with a new one 4 If the light still does not come on check for voltage at the wire terminal If there is no voltage present check the wire between the switch the instrument cluster and fusebox for continuity see the wiring diagrams at the end of this Chapter 5 If the warning light comes on whilst the engine is running yet the oil pressure is satisfactory remove the wire from the oil pressure switch With the wire detached and the ignition switched ON the light should be out If It is illuminated the wire between the switch and instrument cluster must be earthed grounded at some point If the wiring is good the switch must be assumed faulty and replaced Removal 18 3 Pull back the rubber then remove the terminal screw and detach the wiring 6 The oil pressure switch is screwed into the crankcase on the left hand side Remove the belly pan see Chapter 8 and the front g sprocket cover see Chapter 6 for access
