Instruction manual

The regulator and cut-out are accurately set during manufacture. If, under normal

running-conditions, it is found that the battery is continually in a low state of charge, or

is being constantly over-charged, 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.

The A.V.C. Unit is retained to the battery carrier by two bolts with nuts. The four

terminals of the A.V.C. Unit are plainly marked by the letters F.A.D.E. 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

The battery fitted is LUCAS type PUW-7E-4. This is a lead-acid battery in which the

electrolyte is in free liquid form. The voltage is 6 and the capacity is 12 ampere hours.

The negative terminal is earthed to the frame.

The maintenance period of a battery is expressed in terms of time and not miles, as is

general with all other parts of the machine.

The routine maintenance MUST be carried out, irrespective of if the machine is used,

or not.

Maintenance once every 14 days

Remove battery cover, brush dirt from top of battery and remove vent plugs. (There

are three vent plugs.)

NOTE—NEVER bring a naked light near a battery when the vent plugs have been

removed, or when the battery is being charged, as the gas given off by the

electrolyte is highly explosive.
