1 General Information
1.1 Components
Generator
The Mitsubishi generator can be identified visually by its two lower and one upper mounting lugs.
It is mounted to the lower right-hand side of the engine block. It is driven by the same drive belt that drives other engine
ancillaries and requires no periodic drive belt adjustment.
The generator has three phases, incorporating a rotor with six pole pairs fitted and two internal cooling fans; one on the
drive-end and one on the slip-ring end. The rotor is supported by ball bearings in both the drive and slip-ring end
housings. Surrounding the rotor is a stator, which has a three phase delta connected output winding construction on a
ring shaped lamination pack.
The output of the stator winding is rectified by eight diodes that are contained within the slip-ring end housing. Excitation
current is supplied to the rotor field coil via the voltage regulator, the brushes and slip-rings. The electronic voltage
regulator requires no adjustment in service.
The generator has four external connections (refer to Figure 6D1-1 – 1):
G8 – X1 pin A to the battery positive terminal X86 – B (circuit 1) – battery charging,
G8 – X2 pin 1 to the ECM connection A43 – X1 pin 43 (circuit 225) – regulator monitoring,
G8 – X2 pin 2 to the ECM connection A43 – X1 pin 21 (circuit 23) – battery voltage sensing, and
ground connection via the installation bolts.
Generator Types
The 100 amp generator is fitted as standard to all vehicles, except as detailed in the following:
The 120 amp generator is fitted as standard to vehicles fitted with the following production options:
T82 (daytime running lights – Telstra option) or
9C1 (national police pack).
The 120 amp generator is also available as a production option.

Page 6D1-1–4
Charging System – V6 Page 6D1-1-5
1.2 System Operation
Operation
With the ignition switch in the ON position and the engine at rest, current is supplied via the regulator to G8 – X2 pin 1
(circuit 225) and to the engine control module (ECM) at connector A43 – X1 pin 43. This initiates current flow (within the
regulator) from the generator G8 – X1 pin A, to the brushes and rotor winding, to ‘excite’ the circuit.
The current in the rotor winding creates magnetic fields between adjacent rotor poles.
With the engine running, the rotor spins, the stator windings cut through this field and induce voltage. As the engine
speed is increased, this induced voltage increases. Current then flows through the three-phase diode bridge in the
rectifier to convert the AC voltage to DC. This is supplied to the G8 – X1 pin A output and then to the battery terminal
X86 – B (circuit 1).
The regulator monitors the voltage to the battery. When this voltage reaches approximately 14.5 V, the regulator opens
the circuit through the rotor winding, causing the generator output voltage to drop. When the regulator senses a voltage
below a preset voltage, the regulator closes the circuit through the rotor winding and voltage to the battery again
increases. This cycle repeats very rapidly.
Alternator Warning
NOTE
All generator faults are displayed as Check
Alternator Warning on the instrument cluster
MFD, refer to Section 12C Instrumentation.
The ECM monitors the voltage on circuit 23 at A43 – X1 pin 21 and circuit 225 at A43 – X1 pin 43.
The voltage at regulator G8 – X2 pin 1(circuit 23) will remain low when a fault condition is detected in the generator or
associated external circuits. The voltage remains low (while the ignition switch is on) until the fault is repaired.
For more information on the alternator warning refer to Section 12C Instrumentation.
Fault conditions include the following:
open circuit or excessive voltage drop in circuit 1,
open circuit in the generator phase connection,
overcharging conditions,
short circuit in the regulator output stage,
open circuit in the rotor winding,
poor contact between the rectifier and the regulator, and / or
high resistance in the fusible link assembly.

3 Minor Service Operations
3.1 Safety Precautions
Observe the following precautions. Failure to observe these precautions will result in serious damage to the generator.
Only use the generator and voltage regulator in a negative ground system.
Always refer to Section 00 Warnings, Cautions and Notes before disconnecting the battery.
When installing a battery, fit the positive (+) cable to the battery before fitting the negative cable.
When a slave battery is used for starting purposes, ensure that both batteries are connected in parallel. That is,
positive terminals connected and negative terminals connected.
Only use jumper leads that have surge protection.
Disconnect both battery cables when charging the battery. This isolates the generator from the battery and from the
external charging equipment.
Do not operate the generator within an open circuit or without a battery in the circuit.
Do not disconnect the battery while the generator is running.
Do not attempt to polarise the generator.
Do not connect generator connector G8 – X2 pin 1 to 12 V (the battery or ignition circuits).
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.
Ensure the generator connector G8 X2 pin 1
has a maximum sinking curren t o f 50mA.

3.2 Maintenance
LT Section No. — 02–140
Regular Checks
Check the following at regular intervals:
generator terminals – for corrosion and loose connections,
wiring – for continuity and damaged insulation,
mounting bolts – for tightness,
drive belt – for alignment and wear, and
drive pulley – for damage and warping.
NOTE
The drive-belt adjustment for the engine
ancillaries (i.e. generator and water pump) is
provided by a spring-loaded tensioner. Therefore,
the drive belt does not require manual
adjustment.
Lubrication
High tolerance bearings are used in this generator. If the bearings are removed during the generator disassembly, new
bearings must be installed to restore the generator to original specification. The ball bearings supporting the rotor shaft
are pre-lubricated and sealed. Do not attempt to lubricate these during servicing.

3.3 On-vehicle Testing
LT Section No. — 02–140
On-vehicle Checks 100A Generator
Prerequisites
Before testing the generator output, ensure that:
all generator circuit connections are clean and tight,
the generator is always connected to the battery during testing (to prevent damage to the diodes),
the battery is fully charged, and
the specific gravity does not vary more than 0.025 between cells. (It is recommended the average specific gravity is
1.260 or higher). Refer to Section 12A Battery.
Carry out a load test on the battery to determine its ability to supply and accept current. This is a good indicator of the
general condition of the battery. For details of battery testing, refer to Section 12A Battery.
Inspect the drive belt and tensioner markings to determine if the drive belt is within operating limits. Replace the belt
if it is excessively worn or outside the operating range of the tensioner. For further details, refer to
Section 6A1 Engine Mechanical – V6.
Generator Test
Regulating Voltage Test
NOTE
Leave the generator wiring harness connector
G8 – X2 connected. Circuit 225, G8 – X2 pin 1, is
necessary as it provides initial field excitation.
1 Ensure the ignition switch is in the OFF position and all
electrical equipment is turned off.
Refer to Section 00 Warnings, Cautions and
Notes before disconnecting the battery.
2 Disconnect the battery ground cable at the battery.
3 Disconnect the generator positive lead (circuit 1) from
the generator G8 – X1 pin A. Connect the positive lead
of a multimeter set to measure current (1) to G8 –
X1 pin A (2).
4 Connect that multimeter’s negative lead to the
disconnected generator positive lead (3).
5 Connect the positive lead of a multimeter set to
measure voltage, (4) to G8 – X1 pin A (5).
6 Connect that multimeter’s negative lead to a good
ground connection on the generator housing (6).
Insulate the terminal of the generator positive
lead (circuit 1) to prevent contact with any
metal part of the vehicle. If the terminal is
grounded, damage to the charging circuit
can result when the battery is reconnected.
