Control box connections
Normally, during day-time running, when the battery is in good condition, the dynamo
gives only a trickle charge, so that the ammeter reading will seldom exceed 1 to 2 amperes,
i.e.: —Half to one division of scale.
If, under normal running conditions, it is found that the battery is continually in a low
state of charge, or is being constantly overcharged, then the regulator setting should be
checked by a qualified electrician and, if necessary, re-set. Whenever possible, this
should be carried out by a Lucas Service Depot or Agent.
T O REMOVE C O N T R O L B O X
The A.V.C. unit is held in sponge rubber and housed in a partition at the rear top corner
of the tool box. To remove it, open the box lid, grasp the unit between the fingers and
thumb of one hand, and gently and firmly pull it out. Refit with cover outwards.
The four terminals of the control box are plainly marked by the letters D.E.A.F. Wires
from F and D go to similarly marked terminals on the dynamo. The A terminal is
connected to one of the ammeter terminals and the E terminal is "earthed".
We specially warn against unskilled meddling with the settings of the regulator and the
cut-out contacts.
BATTERY—ALL MODELS—MLZ9E
A lead-acid battery LUCAS type is used on all models.
The voltage is 6, the capacity is 12 ampere hours, at the 10 hour rate.
Machines are issued with dry charged batteries, the acid is filled by the dealer.
All models have the POSITIVE battery terminal connected to "EARTH".
BATTERY UNIT—ALL MODELS
The battery is housed in the front portion of the tool box and retained in position on its
platform by a stout rubber strap.
To remove the battery, grasp the rubber strap with the fingers between the strap and
the battery case. Push the strap downwards sufficiently to release the metal toggle
from the strap retaining clip. The battery can now be lifted out.
