Removal

15.17 Slacken the screw (arrowed) and free the cable from the guide cluster, noting how it fits, and unscrew the knurled ring securing the speedometer cable as it becomes accessible (see illustrations).

12 To remove the digital trip meter, trace the wiring from the cluster and disconnect it at the connector (see illustration). Unscrew the two nuts, noting the washers, and remove the meter, noting how it fits.

13 Installation is the reverse of removal. Check the rubber grommets for damage, deformation and deterioration and replace them with new ones if necessary. Make sure that the wiring connectors are correctly routed and secured.

14 Remove the fairing (see Chapter 8).

15 Unscrew the knurled ring securing the speedometer cable in the instrument cluster and detach the cable, noting how it fits (see illustration 15.2 or 15.11c).

16 Undo the screw securing the lower end of the speedometer cable in the drive housing on the right-hand side of the front wheel and detach the cable, noting how it locates (see illustration).

is a fault, first check that the speedometer cable is securely attached at each end. then remove it (see below) and check that the inner cable has not broken, and If it hasn't check that it rotates freely within the outer cable. It is also worth removing the front wheel (see Chapter 7) and checking the drive gear. Otherwise, take the speedometer to a Honda dealer for assessment.

2 Remove the instrument cluster (see Section 15).

3 On H and J (1987 and 1988) models, undo the cover screws on the back of the housing, noting any wiring clamps secured by the screws, and lift off the front cover. Note how the rubber seal and inner cover fit and remove them if required. Check the condition of the seal and replace it with a new one if it is damaged, deformed or deteriorated.

4 On K to X (1989 to 1999) models, undo the cover screws on the back of the housing and remove the outer cover, the lens and the inner cover (see illustrations).

5 Undo the two screws securing the speedometer and remove it from the base, noting how It fits (see illustration).

6 Installation is the reverse of removal.

Tachometer check

7 Special instruments are required to properly check the operation of the meter itself. If there is a fault, first check the fuses (see Chapter 5). If they are good, remove the fairing (see Chapter 8).

8 On H to R (1987 to 1995) models with three wires to the tachometer, disconnect the cluster wiring connectors, then 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, check for continuity to earth in the green wire, and for continuity to the ignition control unit in the black/yellow wire, again using the Wiring Diagrams. Otherwise, take the tachometer to a Honda dealer for assessment.

9 On T to X (1996 to 1999) models, Honda specify their own Imrie diagnostic tester (model 625), or the peak voltage adapter (Pt. No. 07HGJ-0020100) with an aftermarket digital multimeter having an impedance of 10 M-ohm/DCV minimum, for a complete test. If this equipment is available, connect the positive (+) lead of the voltmeter and peak voltage adapter arrangement to the yellow/green wire terminal on the tachometer and the negative (-) lead to a good earth (ground). Turn the engine over on the starter motor and note the voltage reading obtained. If the reading Is 10.5 V or above, the tachometer is faulty. If the reading is below 10.5 V but above 0 V, the ignition control unit is probably faulty. If there is no voltage, detach the wires and check for continuity to the ignition control unit in the yellow/green wire. If there is no continuity check the wiring and connectors for faults, referring to the relevant Wiring Diagram at the end of the Chapter. If there is continuity, the ignition control unit Is probably faulty. If there is the correct voltage, check for continuity to earth in the green wire, again using the Wiring Diagrams. Otherwise, take the tachometer to a Honda dealer for assessment.

Digital trip meter check

59 First check the fusebox fuses (see Section 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

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
