3.3 On-vehicle Testing
Generator On-vehicle Checks
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 6D1-3 Battery – V6.
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 6D1-3 Battery – V6.
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 6A1 Engine Mechanical – V6.
Generator Test
Regulating Voltage Test
NOTE
Leave the generator E-4 wiring harness
connector connected, 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 1.2 WARNING, CAUTION and
NOTES before disconnecting the battery.
2 Disconnect the battery ground cable P-5 at the battery.
3 Disconnect the generator positive lead P-9 from the generator . Connect the positive lead of a multimeter
set to measure current (1) to P-9 (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 P-9 (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 P-9 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.

20 Reduce the engine speed to idle.

On completion of the generator output test,
return the engine to idle and disconnect the
loading device from the battery terminals.
This prevents excessive battery discharge.
21 Stop the engine.

23 Remove the multimeters.
24 Reconnect the generator positive lead P-9.
25 Reconnect the battery ground cable P-5 to the battery.

Ensure the generator connections are clean
and tight.
1 Connect the positive lead of a multimeter set to measure voltage to the generator terminal P-9.
2 Connect the negative lead of the multimeter to the battery positive post.
3 Switch the headlamps on.
4 Start the engine.
5 Increase the engine speed to approximately 2500 r.p.m.

• There is no Current DTC but a History DTC is stored.
Diagnostic Table
Checks Actions
Preliminary
• Perform the Preliminary Checks, refer to 7.1 Diagnostic Requirements,
Precautions and Preliminary Checks.
