Fault finding guide
If having followed the correct steps to start
battery charging the charger does not
operate as described, then check as
follows:
No charging indicator
The connection between the charger and
the batteries has not been made.
Mains supply
Check that the mains supply is on, that
any fuses are intact and that the charger
is switched on.
Deeply discharged batteries
If the battery voltage is below 16 volts the
charger will not commence charging.
Batteries and charging
General
The external charger (Fig. 45) has been
designed to charge two 12 volt Dryfit Gel
type batteries.
Safety features
The chargers have features which prevent
hazards or accidents occurring as a result
of connecting batteries the wrong way
round, overheating caused by fault
conditions, or attempting to charge wrong
voltage batteries.
The majority of charger sizes are
electrically double insulated and no earth
connection is required. Some larger sizes
may be electrically earthed and this will
be clearly stated on the label.
The 3 pin UK mains input plug contains a
replaceable fuse. The rating of this fuse
is shown on the charger label. Always
replace with the same type and size of
fuse as specified. Fitting of different fuses
can result in damage to the charger or
failure of the charger to operate properly.
If your charger has been specified for
use in Continental Europe it will contain a
European two pin plug which does not
have a fuse. In this case the fuse is
located in the fascia panel of the charger.
