be considered when a battery is run down or low in
charge.
The procedures which follow will assist in a logical
sequence of pinpointing specific troubles.
Always determine the cause of failure as well as
making the repair.
1. Polarity and connections. The alternator is for
use on negative earth electrical systems only.
Polarity cannot be reversed by ’flashing’ the field
terminals as with the dynamo. Any attempt to do
so will damage the alternator.
2. Refitting Vehicle Battery. Reversed battery
connections will damage the alternator rectifiers.
When refitting, first fit the positive (+) connector to
the battery positive (+) terminal. Then fit the
negative (-) connector to the negative (-) battery
terminal.
3. Battery Charging. First disconnect the battery
negative cable, thus isolating the alternator from
the battery and external charging equipment.
4. Battery Connections. The battery must never be
