Short
journeys without the battery can be made with
the switch in the
"EMG"
position.
To
do this, the
cable normally connected to the battery negative terminal
must be connected to an earthed point on the machine.
If
lights are required when the battery
is
disconnected,
use the headlights and keep the engine speed

to
prevent excessive voltage rise.

Battery.
Batteries
on
machines supplied
in
England, Scotland
and Wales are supplied
filled
and charged ready for
use.
Batteries on machines supplied overseas are in the
"
dry charged
"
condition. These require only
filling
with sulphuric acid of 1
·250
density and allowed to stand
for one hour before being put into service.
If
an
"
unformed
"
dry battery
is
fitted it must be
filled
with acid
of
1
·285
density and given a long slow
continuous charge of
0·8
amps. for 32 hours before being
put into service. This process
is
necessary to form the
correct chemical compounds in the battery plates, and
if
not carried out the battery will have a short
life
and
a high resistance which
will
prevent it accepting the
correct rate of charge from the rectifier.
