6.7 Note how
are fitted before
disturbing them
7.2 Tail lamp lens is retained by two
screws
8.1 Brake switch can be adjusted by
means of nut
8 Rear brake stop lamp
adjusting
1 To adjust the stop lamp switch hold the switch body and
with the correct size spanner screw down the adjuster nut thus
raising the rear brake light switch and making it operate sooner.
Never adjust too tightly; the light should come on just as the
first braking pressure is felt.
9 Front brake stop lamp
location and replacement
1 In order to give as much warning as possible to other road
users of the braking of the machine, a front brake switch is
incorporated in the front brake lever assembly.
2 There is no means of adjustment if it malfunctions, in which
case the switch must be renewed.
3 To replace the switch, the headlamp reflector unit must be
taken off and the wire from the switch disconnected. Take off
the front brake lever and feed the switch and wires back out
towards the lever pivot. Replace the new switch in the reverse
order.
10 Instrument ilumination and warning lamps: replacing
bulbs
1 The instrument illumination and warning lamp bulbs are
retained by rubber bulbholders which are a push-fit in the base
of the speedometer and/or warning lamp cluster, as appropriate.
To renew speedometer-mounted bulbs, pull the
and remove the bulb by turning it anticlockwise. New bulbs are
fitted by reversing the above procedure.
2 On
and E models it may be necessary to remove
its mounting bolts and to lower the headlamp assembly so that
the two screws can be removed which secure the cluster
housing to the bracket; the housing can then be raised
sufficiently for the bulbholders to be unplugged. These bulbs are
of the capless type and are pressed into their sockets; be careful
not to damage the fine wire terminals on fitting the new bulb.
11 Flashing indicator lamps
1 The forward facing indicator lamps are connected to 'stalks'
which are attached to the headlamp brackets. The hollow stalks
carry the leads to the lens unit. The rear facing lamps are
mounted on similar, shorter stalks, at a point immediately to the
rear of the dualseat.
2 In each case, access to the bulb is gained by removing the
plastic lens cover, which is retained by two screws. Bayonet
fitting bulbs of the single filament type are used.
12 Flasher unit: location and replacement
1 The flasher relay unit is located under the dualseat, being
rubber-mounted to the frame top tube.
2 If the flasher unit is functioning correctly, a series of audible
clicks will be heard when the indicator lamps are in action. If the
unit malfunctions and all the bulbs are in working order, the
usual symptom is one initial flash before the unit goes dead; it
will be necessary to replace the complete unit if the fault cannot
be attributed to any other cause.
3 Take great care when handling the unit because it is easily
damaged if dropped.
13 Headlamp dip switch
1 The headlamp dip switch is incorporated in the handlebar
controls and is used to dip the main headlamp beam to avoid
dazzling oncoming traffic.
2 Should this unit malfunction it is necessary to fit a new
replacement since repairs are usually impracticable. A sudden
failure when changing from one beam to the other can plunge
the lighting system into darkness, with disastrous conse-
quences.
