Generator Noise Diagnosis
Diagnostic Aids
Noise from a generator may be due to electrical or mechanical noise. Electrical noise or magnetic whine usually varies
with the electrical load placed on the generator and is a normal operating characteristic of all generators. When
diagnosing a noisy generator, it is important to remember that loose or misaligned components around the generator
may transmit the noise into the passenger compartment and that replacing the generator may not solve the problem.
Step
Test the generator for proper operation using the Generator
1 Tester. Refer to "Charging System Test".
Is the generator operating properly?
1. Start the engine. Verify that the noise can be heard.
2. Turn OFF all accessories.
3. Turn OFF the Ignition.
WARNING
!
Make sure that the load is completely turned off
before connecting or disconnecting a carbon pile
load tester to the battery. Otherwise, sparking
could ignite battery gasses which are extremely
flammable and may explode violently.

4. Connect a carbon pile tester to the vehicle.
5. Connect an inductive ammeter probe to the output circuit
of the generator.
6. Start the engine.
7. Increase engine speed to 1,500 RPM.
8. Increase and decrease the amount of load placed upon
the generator.
9. Listen for the noise.
Does the noise increase and decrease with the amount of load
placed upon the generator by the carbonpile tester?
1. Turn OFF the engine.
2. Remove the drive belt. Refer to "Drive Belt Replacement:
".
