CHARGING
Connection of the charger to batteries that are fitted in vehicles:
1. The mains cable should not be connected to the wall socket when connecting or
disconnecting the battery leads.
2. Identify the pole that is earthed (connected to chassis). Earth is normally
connected to the negative terminal.
3. Charging of negatively earthed battery: Connect the red lead to the positive pole
of the battery and the black lead to the vehicle chassis. Be careful not to connect
the black lead close to the fuel pipe or the battery.
4. Charging of positively earthed battery: Connect the black lead to the negative pole
of the battery and the red lead to the vehicle chassis. Be careful not to connect the
red lead close to the fuel pipe or the battery.
Connection of the charger to batteries that are not fitted in vehicles:
1. The mains cable should not be connected to the wall socket when connecting or
disconnecting the battery leads.
2. Connect the red lead to the positive pole of the battery and the black lead to the
negative pole.
