The readings for each of the three cells should be approximately the same. If
one cell gives a reading very different from the others it may be that the electrolyte
has been spilled or has leaked from this particular cell or there may be a short-circuit
between the plates. If leakage from the top of the battery is known to have occurred,
sue to a spill, the battery should be topped-up with battery acid of suitable specific
gravity.
Never leave the battery in a discharged condition as it will suffer permanent
damage. When standing idle, the battery should be given a freshening charge at least
once a month. Twelve hours at one amp. is recommended. Keep the top of the
battery clean and smear the terminals with vaseline to prevent corrosion.
A positive earth wiring system is employed. Make sure that the battery is
connected correctly, i.e. with the positive or
+
side of the battery connected to earth.
Running Without a Battery
If it is required to run the machine without a battery in position, unscrew the
terminals and remove the battery. The negative lead (brown) which previously went
to the battery must be insulated, and the stop light must be disconnected. If this is not
done the rectifier may be seriously damaged.
The machine must only be run without a battery in an emergency. The lighting
equipment can be used but if the engine is revved excessively the bulbs will blow and
serious damage may result to the lighting equipment.
Alternator
The flywheel comprises six high-grade cast magnets with laminated pole pieces. It is
SELF-KEEPING
and may be separated from the stator without any loss of magnetism.
The laminated stator has six salient poles, four of which are wound with coils of
enamelled copper wire.
The set requires very little maintenance and if the following points are observed
the life of the machine should prove trouble-free. Check, and, if necessary readjust
the contacts once every 5,000 miles (8,000 Km.) as described on page 10.
Occasionally clean the contacts by inserting a dry smooth piece of paper
between them and withdrawing whilst the contacts are in the closed position. Do not
allow the engine to run with grease or petrol on the contacts or they will start to burn
and blacken. If they do, lightly polish with a piece of smooth emery cloth.
Smear the cam lubricating pad with a little grease every 5,000 miles (8,000
Km.). Do not run with a faulty or damaged high tension lead, and occasionally clean
away mud and dirt from around the high-tension insulator.
