ALTERNATOR VOLTAGE REGULATOR REPAIRS IN HAMILTON

About the alternator voltage regulator:

The alternator voltage regulator is used to regulate the voltage level in your cars electrical system and for charging the battery of your car correctly. When a steady, reliable voltage is needed, then the voltage regulator is the preferred device. It generates a fixed output voltage that remains constant for any changes in an input voltage or loads current conditions. alternator regulatorIt acts as a buffer for protecting components from damages. This is because all modern automobiles have a 12 volt, DC electrical system.

 

Symptoms of a faulty alternator regulator:

Undercharging of a car battery

A symptom of an issue with the alternator voltage regulator is the car battery going flat.

One-third of alleged battery faults are simply flat batteries caused by vehicle undercharging or leaving lights on. Breakdown surveys by the Automobile Association consistently indicate that drivers leaving electrical accessories on, charging system faults (such as a faulty alternator voltage regulator) and poor battery maintenance are the major causes of battery problems.

Overcharging of a car battery

An alternator voltage regulator should keep the battery voltage below 15 volts DC while it is charging. If it goes above 15 volts you your car can start to blow headlight and other bulbs, and damage can occur to sensitive electronic car components.

The potential sign that your battery is being overcharged is that your battery terminals keep accumulating a form of corrosion.

Overcharging is charging beyond the time necessary to fully charge the battery or conducted at an excessive rate in amps for the particular battery. It produces erosion and corrosion of the positive material and causes the internal battery grids to fracture reducing their ability to carry the current to start the car.

Overcharging is usually associated with high battery electrolyte temperatures resulting in rapid deterioration of the car battery internal plates and separators. Overcharging may cause buckling of the internal battery plates leading to perforation of the separators and internal short circuits.

Intermittent charging of car battery

Sometimes the alternator voltage regulator can work intermittently due to failing components, or poor internal connections. This may mean sometimes your alternator will charge your car battery, and other times it may randomly not charge your car battery.
