Frequently Asked Questions (FAQs)
1. What are the symptoms of worn alternator brushes?
Symptoms of worn alternator brushes may include the ignition warning light not coming on, not going out, or staying dim. It is important to investigate and diagnose the cause of these issues to determine if the brushes or slip rings need to be replaced.
2. Do alternators still have brushes?
Yes, alternators still have brushes. These brushes make contact with the slip rings, allowing the alternator to generate the necessary electrical signals to power vehicles.
3. What do both alternator brushes make electrical contact with?
Both alternator brushes make electrical contact with the commutator. The commutator transfers the current to the external load and ensures the torque on a DC motor does not reverse when the coil moves through the magnetic field. This allows for the proper functioning of the alternator.
4. Can you change the brushes on an alternator?
Yes, the brushes on an alternator can be changed. It is a regular process that may be necessary when there are issues in the charging system or during the dismantling of the alternator or voltage regulator.
5. What happens if you put carbon brushes in the wrong way?
If carbon brushes are installed the wrong way, only the tip of the brush will make contact with the commutator instead of the curved end. This can cause issues such as a loud ratchety sound, excessive sparking, or a lack of power.
6. Is it safe to wash an alternator?
While you can clean an alternator with water, it is important to avoid directly pressure washing it. Pressure washing can damage seals and potentially cause further problems. It is best to exercise caution when cleaning the engine bay.
7. Do I have to remove my alternator to get it tested?
To have an alternator tested at an auto parts store, it is typically necessary to remove it. Many auto parts stores offer free alternator testing, along with testing for starters and batteries. When connected to a terminal, an alternator should test between 12 and 13.5 volts.
8. What are the two wires connected to the alternator?
The two main wires connected to the alternator are the exciter wire and the positive/negative cables. The exciter wire is connected to the L terminal of the alternator and is responsible for turning on the voltage regulator. It helps generate the voltage required for the alternator to start running.
9. What is an alternator without carbon brushes?
An alternator without carbon brushes is referred to as a brushless alternator. These alternators have eliminated the use of brushes, resulting in fewer moving parts and a longer overall product life. They are not susceptible to issues caused by dust accumulating on the brushes.
