3. DESCRIPTION OF TECHNICAL EQUIPMENT
Ignition and lights are effected by an A. C. Magdynamo. The magdynamo is a
small alternator in which rotor (permanent magnet) while rotating in fixed coils of
the stator induces the current required for the ignition of the mixture as well as
for the lights and the charging of the battery. The three circuit system is arranged
so that the ignition and the headlamp main beam are supplied direct from the
magneto alternator, whereas the battery serves exclusively as an auxiliary source
for the parking light, the tail lamp, stop light, horn and also to facilitate easy
starting.
The magneto stator is secured by two M6 bolts and clamps to the crankcase. The
entire housing can be rotated through 36 degrees for ignition advance setting. The
contact breaker complete is fitted on the stator. Its position on the stator is located
by the manufacturers by means of an Oscillograph to ensure most suitable
tension for ignition and lighting, and this position should never be altered under
any circumstances.
The terminal base fitted on to the stator has the following terminal numbers: -
Number 11 Voltage supply for Ignition
“ 20 Voltage supply for battery charging
“ 55 Voltage supply for Head Light
The rotor is fitted on to the Crank Shaft and held by a bolt together with the cam
controlling the contact breakers.
The battery-14 AML, 6V
- with lead plates and electrolyte (diluted sulphuric acid)
is located in the L. H. side box and connected to the frame with its positive (plus)
pole. A 15 Amp. fuse is fitted in a case next to the battery.
A Rectifier
(which converts the A. C. magneto current to D. C. for the charging
of the battery) is located on the battery box and is accessible after the dual seat
has been removed. It does not require any maintenance and any manipulation
whatsoever with it should be avoided.
