How does the auto electrical system work?

Modern cars are now fitted with sophisticated engine and body control systems that monitor speed, engine temperature, fuel usage, outside air temperature, transmission operation, air conditioning and much more. With this level of complexity, the system continuously monitors electrical circuits to ensure every component is operating within the range intended. Any faults or variances outside the operating parameters are logged by the system where, usually, a warning light will display to advise the driver that something is not operating correctly.

Auto electrical system components

As well as the central system, there are various other elements that form part of your auto electrical system including your car battery. These include sensors, actuators, alternators, battery charging systems, oxygen sensors, solenoids, air valves, step-up motors and other devices. All these elements work together to deliver improved power and performance with reduced fuel consumption and emissions.

The warning signs

Some of the signs that there are problems with your auto electrical system include:

  • Car won’t start.
  • Battery warning light comes on.
  • Check Engine warning light comes on.
  • Engine cuts out when car is moving.
