Symptoms of a damaged rectifier; a persistent flat battery
or persistent overcharging. Note that if the battery is connected
up incorrectly, a damaged rectifier is very likely to result.

Battery: charging procedure and maintenance
1
Whilst the machine is in normal use it is unlikely that the
battery will require attention other than routine maintenance
because the generator will keep it fully charged. However, if the
machine is used for a succession of short journeys only, mainly
during the hours of darkness when the lights are in full use, it is
possible that the output from the generator may fail to keep
pace with the heavy electrical demand. Under these circum-
stances it will be necessary to remove the battery from time to
time to have it charged independently.

rapid charge up to 2 amps can be given in an emergency, but
this should be avoided if possible because it will shorten the life
of the battery. See accompanying table.

cover them with Vaseline (not grease) to protect them from
further attack. If a vent tube is fitted, make sure it is not obs-
tructed and that it is arranged so that it will not discharge over
any parts of the machine. If topping-up is necessary, use only
distilled water to maintain the electrolyte level between the
upper and lower level lines on the transparent casing.

weeks or so, in order to maintain it in good condition.
