94. Charging.
If the previous tests indicate that the battery is
merely discharged, and if the acid level is correct, the
battery must be recharged from an external supply.
Charge the battery with a constant current of 1.2
amperes until the specific gravity of the electrolyte in
the cells remains constant.
If the battery does not respond to a freshening
charge it must be put through what is known as a
"cycle."
First charge as described above for a period of 10
hours and then discharge at the rate of 1.2 amperes.
The time taken to discharge should be 7-8 hours. If the
battery discharges in a shorter time, repeat the
charging and discharging cycle. If the efficiency of the
battery is not improved by this process there is
probably an internal fault and the battery should be
replaced.
HEADLAMP. (Lucas Type DU42).
95. Removing Lamp Front and Reflector.
To remove the lamp front and reflector press back
the fixing clip at the bottom of the lamp. When
replacing the front locate the top of the rim first, then
press on at the bottom and secure by means of the
fixing clip.
To remove the bulb holder, press back the
securing springs.
98. Setting and Focussing.
The lamp must be set to ensure that the beam is
projected below the horizontal.
To obtain the best driving light the bulb should be
correctly focussed in the reflector. To adjust the
position of the bulb, remove the lamp front and
reflector and slacken the screw on the clamping clip at
the back of the reflector. Slide the bulb holder
backwards or forwards until the best lighting is
obtained and finally tighten the clamping screw.

CABLES.
100. Positive Lead to Battery.
Before making any alterations to the wiring or
removing the switch from the headlamp, disconnect
the positive lead at the battery to avoid the danger of
short circuits. The lead from the positive battery
terminal is connected to the lead from the switch by
means of a brass connector. The connector is
insulated by a rubber sleeve which must be pushed
back to allow the connector to be unscrewed. Do not
allow the brass connector to touch any metal part of
the machine as this will short circuit the battery.
When connecting up again, pull the rubber sleeve
over the connector.

97. Cleaning.
Care must be taken, when handling the reflector
to prevent it from becoming finger marked. It can,
however, be cleaned by polishing with a fine chamois
leather. Metal polishes must not be used.
98. Bulbs.
The main bulb should be 6 volt, 24 watt,
doublefilament type. If the filament in use burns out,
reverse the bulb in its holder, thus bringing the other
filament into operation. Re-focus the lamp to obtain
the best results from the altered position of the
filament.
The pilot bulb is 6 volt, 3 watt S.B.C.
TAIL LAMP.
(Lucas Type L-WD-MCTI or L-WD-MCTIA).
99. Removing Lamp.
To remove the cover carrying the red glass, twist
and pull away from base. When replacing, position
the locations in the cover over the spring and push
home.
The bulb should be 6 volt, 3 watt, S.B.C.
