Batteries and charging

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 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. This will be indicated by the bi-coloured indicator light alternating between orange/green (Fig. 27).
