the battery is fully charged. Such a freshening
charge
should last for no more than 4 hours, at the
normal recharge rate of the battery. During the
charge the electrolyte must be kept level with the

distilled water. Check the specific gravity of the
acid at the end of the charge; if 1 ·260 acid was used
to fill the battery. the specific gravity should now
be between 1 ·270 and 1 ·290; if 1 ·210, between
1·210 and 1·230.
GENERATOR
GENERAL
The generator is a shunt-wound, two-pole, two-brush
machine,
arranged
to work in conjunction with a
Lucas regulator unit. A fan, integral with the driving
pulley, draws cooling air through the generator,
Inlet and outlet holes being provided in the end
brackets of the unit. The armature is supported at
the drive-end in a ball race bearing and at the
commutator-end in a porous bronze bush.
ROUTINE MAINTENANCE
Lubrication
Inject a few drops of engine oil into hole marked
"Oil" at the end of the C.E. bearing housing (See
Fig. 2). The felt ring acts as a reservoir.
Inspection of Brushgear
The brushgear should be inspected periodically
(See page 7).

1. Inspect the driving belt and adjust if necessary
(see Section 8).
2. Check the Lucar connections on the commu­
tator-end bracket. The larger connector
carries the main generator output, the smaller
connector the field current (see Fig. 2).
3. Switch off all lights and accessories, pull off the
connectors from the terminals of the generator
and connect the two terminal blades with a
�hort length of wire._
4. Start the engine and set to run at normal
Idling speed.
