WARNING LIGHT ASSIMILATOR
|
|
|
|
|
Lucas Type 3AW (1971 and later models)
|
|
This is an electro-mechanical device for
ignition warning light control.
|
|
With the ignition switched on, the warning light
is supplied with battery current; when the engine
is started and the alternator output reaches 6
volts approximately, the contacts inside the unit
open and break the warning light circuit, switching
off the warning light.
|
|
should the warning light fail to light when the
ignition is switched on and with the engine
stationary, disconnect the White/Brown lead from
the "W L" terminal of the control unit and
temporarily reconnect to the "E" terminal; if the
bulb lights, this indicates that the control unit
is faulty, but should the light still fail, then
the bulb, connections, and associated wiring should
be checked.

MASTER SWITCH (1971 and later models)
|
|
|
|
|
The key operated switch is located to the front
of the left hand accessory cover. The switch
controls ignition and also energises the lighting
system. The switch is a sealed unit requiring no
attention other than a routine check on
connections. The four switch positions are shown
below in Fig. J4.
|
|
|
|
|
The Switch Positions are:
|
|
|
|
|
1.
|
Parking Lights Only
|
|
|
The key may be removed in this position enabling
the machine to be parked safely at night.
|
|
2.
|
Off Position
|
|
|
Again the key may be removed leaving all
circuits isolated.
|
|
3.
|
Ignition Only
|
|
|
The key cannot be removed. This position is used
during normal daytime running.
