Disassembly - Isuzu C22NE Workshop Manual

STARTING AND CHARGING SYSTEM 6D3-13
5. During current output tests please make sure that the
ammeter is securely connceted into the charge circuit.
6. Some battery powered timing lights can produce high
transient voltages when connected or disconnected. Only
disconnect or connect timing lights when the engine is
switched off.
7. Make sure the warning lamp circuit is functioning normally
before commencing tests.
8. Battery isolation switches must only be operated when the
engine is stopped.
9. To protect the charging system when using 240 volt
chargers it is recommeneded
disconnected whilst charging.
10.Due to the very low resistance value of the stator winding it
may not be possible to obtain accurate readings without
special equipment.
11.12 volts must never be connected to the "L" terminal of the
regulator as this will damage the lamp driver circuit.
12.No loads apart from the warning lamp can be connected to
the "L" termainal.
purpose.

Disassembly

1. Mark the relative positions of the end housings in relation to
the stator assembly to aid reassembly. Use a permanent
marking pen do not use centre punched as this can cause
misalignmnet of the housings.
2. Remove the EP regulator from the slipring end housing by
removing the two screws. Tilt the regulator slightly from the
plug connectin until the regulator clears the housing, then lift
clear.
3. Remove the four through bolts.
4. Carefully remove the stator assembly along with the slipring
end housing taking care not to put strain on the stator wires.
5. To disconnect the stator from the rectifier assembly, grasp
the stator wires close to the wire loop with a pair of long
nosed pliers, heat the joint with a soldering iron, when the
point becomes plastic apply a slight twisting motion to the
wires, then pull upwards to release the wires. Remove the
stator.
This procedure opens the wire loop to release the stator
connections easily.
6. To remove the rectifier remove the three retaining screw
and the B+ terminal nut and washers.
Note: the B+ bolt and the positive heatsink retaining screw are
fitted with mica insulating washers.
These must be discarded and replaced with new washers and
heatsink compound.
