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 34. 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.

THE ELECTRICAL SYSTEM
(
Bushman model
)
The lighting and ignition systems are fed by a simple 6-pole alternator generating
set supplying the ignition system, which incorporates an ignition coil designed
especially to operate on the energy transfer principle, and also the lights and horn
which are operated through the switches mounted on the headlight body or handlebar
The alternator carries six coils, of which two feed the lights, two more feed the
horn and the remaining two individually serve the external ignition coil and the stop-
The main connections in this system are made by socket connectors to the lighting
switch and by individual insulated snap connectors in the wiring. The connectors are
not intended as plugs and sockets for frequent manipulation and are only for use
when testing or fault-finding. It is extremely important that they should be making
perfect connection, as should all other connection points throughout the system.
The generator consists of two assemblies, namely, the magnetic rotor, and the
stator which carries the six low tension coils. The rotor carries six laminated
magnetic pole pieces; it is self-keeping and may be separated from the stator without
