The best way of checking the setting of the lamp is to stand the motor cycle in
front of a light coloured wall at a distance of about 25 feet. If necessary, slacken the
two screws on the nacelle rim, and move the lamp until, with the main driving light
switched on, the beam is projected straight ahead and parallel with the ground. With
the lamp in this position, the height of the beam centre on the wall should be the same
as the height of the centre of the headlamp from the ground.
Rear Lamp
A single bulb is used for both stop and rear light purposes.
The transparent red plastic portion of the lamp can be removed by unscrewing the
two countersunk screws.
Stop Light Switch
This is operated by the brake rod through a spring. It is desirable to see that any
mud or grease is periodically cleared away from the switch, and the operating
mechanism should be oiled occasionally with thin oil.
Wiring Diagram
A diagram of the electrical circuit appears on page 31. The insulation of the wires
is individually coloured and these colours are indicated on the diagram.
The wiring is connected by means of snap connectors at various convenient places
on the machine and it is desirable occasionally to check it over and make certain that
these connectors are tight.
