IGNITION SYSTEM

I
The ignition system is comprised of Battery,
Ignition Switch, Coil with certain special features,
Electronic Unit, Distributor with inductive pick-up,
two Resistances and Sparking Plugs.
DISTRIBUTOR
The Distributor is driven by a spiral gear on the
camshaft and rotates in a clockwise direction. The
breaker points in the distributor have been replaced
by a pulse generator consisting of a Stator,
Detecting Coil and Permanent Magnet.
The pulse generator is connected to an Electronic
Control Unit (E.C.U.) in which the signal from the
Distributor is converted and amplified. The E.C.U.
is connected to the
coil.
Ignition spark advance is achieved by mechanical
advance and a vacuum diaphram unit. The
advance is mechanically controlled, according to
engine speed, by governor weights inside the
Distributor body and according to engine load by
vacuum control acting directly on the base plate.
As vacuum advance does not operate at idling
speed due to the butterfly plates being closed, a
correctly retarded spark is obtained for starting.
Note:
The dwell angle cannot be
read,
neither can it be
adjusted.
REMOVING - REFITTING
(DISTRIBUTOR) - Fig. 1
Note:
The mixture regulator must be removed to reach
the distributor. Mark the following before
removing the distributor:
1.
Position of distributor body in relation to
cylinder head.
2.
Position of rotor arm in relation to cylinder
head.
This will aid reassembly and avoid having to retime
the ignition:
