The Electrical System - 12 Volt - Bailey 2002 Series Owner's Manual

Chapter 3 CARAVAN SERVICE SYSTEMS
THE ELECTRICAL SYSTEM – 12 VOLT
These units provide, via 230 volt AC, a 12 volt DC supply to the 12 volt
equipment and charging of the caravan battery. Maximum is 10 amps
and incorporates full automatic charging regulation. This means only the
current the battery needs will be supplied, overcharging will not occur.
Ensure that a mains supply is available via the mains inlet socket located
in the battery box compartment and that the RCD/MCB switches are in
the UP position.
12 volt power will now be available to the main control panel.
The battery charger will only function satisfactorily if the battery is in
good condition.
Should a battery contain a faulty cell the charge voltage from the battery
charger will not rise sufficiently to switch the battery charger off and the
battery will eventually boil dry.
The most common cause for batteries to become faulty is when the battery
is discharged below the recommended level, approximately 10V, causing
one or more of the cells to fail.
