EMERGENCY CHARGING
Should the battery become discharged a temporary boost charge can be effected during
daylight running, by an alteration to the alternator connections.
The snap connectors are located behind the frame plate, which is secured by two knurled
screws.
(1) Disconnect the green and yellow and green and black connectors.
(2) Reconnect the green and black to the green and yellow.
(3) Do not interfere with the green and white cable.
It is stressed that this is a temporary measure, prolonged use will adversely affect the
battery.
RECTIFIER
The rectifier is a device to allow current to flow in one direction only. It is connected
to provide full-wave rectification of the alternator output. The rectifier is mounted
on the tool box under the twin seat.
The rectifier requires no maintenance beyond checking that the connections are clean
and tight.
The nut clamping the rectifier plates together must not under any
circumstances be slackened, as it has been carefully set during manufacture
to give correct rectifier performance.
A separate nut is used to secure the rectifier
to the frame of the motor cycle.
NOTE—It is important to check periodically that the rectifier is firmly attached to its
mounting bracket.
LUCAS COIL IGNITION—SINGLES
The coil is clipped to the front frame top tube underneath the petrol tank.
The ignition equipment comprises a model MA6 ignition coil and a model CAIA contact
breaker unit. The contact breaker, together with an automatic timing control, are
located in the engine timing case.
The automatic timing control is centrifugal operated and varies the firing point according
to the speed of the engine.
Lubrication—to be carried out every 6,000 miles.
No grease or oil must be allowed to get on or near the contacts when carrying
out the following procedure.
