Alternator: Service Precautions
NOTE: Alternator charging circuit - The ignition warning light is connected in series with the alternator field circuit. Bulb failure would prevent the
alternator charging, except at very high engine speeds, therefore, the bulb should be checked before suspecting an alternator failure.
Precautions
Battery polarity is NEGATIVE GROUND, which must be maintained at all times.
No separate control unit is fitted; instead a voltage regulator of micro-circuit construction is incorporated on the slip ring end bracket, inside the
alternator cover.
Battery voltage is applied to the alternator output cable even when the ignition is switched off, the battery must be disconnected before
commencing any work on the alternator. The battery must also be disconnected when repairs to the body structure are being carried out using
electric welding equipment.
