Never bring a naked light near a battery with vent plugs removed or when the battery
is being charged; the gas given off by the electrolyte is dangerously explosive.
Battery acid is highly corrosive; therefore, throw away any cleaning rags used to clean
the battery lest their use on other parts of the machine causes rust.
Never let a battery completely run down; if this does occur get it charged as soon as
possible, or its length of life may be seriously shortened.
BULBS B L O W I N G
This can only be due to an open circuit in the battery line and the fault should be located
before new bulbs are fitted. To locate the fault, check in the following order:—
(1) Bad earth connection on battery positive lead.
(2) Loose or corroded battery terminals.
(3) Loose or dirty contact in the 4-hole 2-way connector which is interposed in the
battery negative lead. (Brown wire).
(5) Loose ammeter connection.
(6) Battery dry due to electrolyte evaporating.
