REMOVING THE DIODE
CARRIER - Fig. 18
Electrical System and Instruments M .04:03
Remove alternator from vehicle.
1. Remove screw, nuts and washers holding
plastic terminal guard (4).
2. Unsolder the three diode carrier wires.
3. Remove wires from voltage regulator (1).
4. Remove diode carrier (5). Never dismantle
the diode bridge.
The instrument panel has a red warning light which
works as follows: —
• On switching on ignition it is illuminated.
• As soon as engine starts it goes out.
• If it is illuminated when the engine is running
there is a charging fault.
• If the warning light fails to be illuminated on
switching on ignition, check the following.
CHECK
1. That no connectors are loose or disconnected.
2. That the bulb has not blown.
If the warning light is illuminated while engine is
running there is a charging fault which may be due
to:—
1. Broken alternator belt.
2. Broken charging wire.
3. Alternator internal fault (rotor, stator, diodes or
brushes).
4. Regulator fault.
REMOVING THE BRUSH
CARRIER - Fig. 18
Note:
The alternator need not be removed for the
operation. The brush carrier (1) being fixed to the
regulator is removed in the same way as the
voltage regulator.
REMOVING THE STATOR
1. Remove the voltage regulator (1).
2. Remove the diode carrier (5).
3. Mark the relative positions of the slip ring end
bracket (6), laminations of stator (7) and drive
end bracket (8).
4. Place an old fan belt around the pulley (9) and
clamp the belt in vice jaws, with the pulley as
close to the vice as possible. The friction and
self wrapping action of the belt will provide
adequate reaction to loosening the pulley nut
(10).
5. Remove the assembly from the vice, remove
the nut, spring washer (11), spacer (12) and
pulley (9).
6. Remove the spacer, washer, fan (13), washer,
key (14) and spacer.
7. Remove the nuts, washers, and through bolts
(15).
8. Separate the drive end bracket (8) from the
stator (7), slip ring end bracket (6) and rotor
assembly (16). Withdraw the stator (7) from
the slip ring end bracket (6).
REMOVING THE ROTOR
1. Remove the voltage regulator (1).
2. Remove the diode carrier (5).
3. Mark the relative positions of the slip ring end
bracket (6), laminations of stator (7) and drive
end bracket (8).
4. Place an old fan belt around the pulley (9) and
clamp the belt in vice jaws with the pulley as
close to the vice as possible. The friction and
self wrapping action of the belt will provide
adequate reaction to loosening the pulley nut
(10).
5. Remove the assembly from the vice, remove
the nut, spring washer (11), spacer (12) and
pulley (9).
6. Remove the spacer, washer, fan (13), washer,
key (14) and spacer.
