Table 7.1 Battery charger faults
Problem Cause Possible solution
Error LED (red)
illuminated
1. Connections back to front
2. Short circuit
1. Remove the connection and attach the
cables correctly.
2. Eliminate the short circuit.
There is a battery
connected to the charger,
but the battery charger is
not working
1. Mains voltage absent or too
low
2. Poor contact (or no contact)
between battery and charger
3. Thermal cut-out in the
battery charger
4. A diode bridge has been
connected that is blocking
the battery voltage so that
the battery charger cannot
switch on.
The battery charger requires
a counter-voltage (from a
battery) to activate it.
1. Measure the mains voltage. This has to be
above 180VAC.
2. Check the connection and the cables.
3. The loading process will continue
automatically once the charger has cooled
sufficiently.
4. The battery charger must have a D+
connection if it is to work properly. Use a
diode bridge of the same brand as the
charger
There is no battery in the
charger and you cannot
measure any voltage
The battery charger requires a
counter-voltage (from a battery)
to activate it.
Connect a battery to the charger and repeat
the measurement.
