Electrical Systems

Today's auto electrical systems are complex. They are getting more intricate and are stressing the limits of current technology. Despite this, they are basically the same design as 30 years ago.

The electrical system consists of the battery, the alternator, the starter and the computer. Each of these components is dependent upon the others for the electrical system to function properly. Certain symptoms can be the result of one or more faulty electrical parts.

Some of the basic signs you need to have your vehicle inspected include:

  • Turn signal flashing at a different speed - This can be from a bad bulb or faulty wiring.
  • Brake light on dashboard lit - This can be from a bad bulb or faulty wiring.
  • Accessories such as the heater not turning on - This may be from a burned out fuse.
  • Dashboard lights periodically go dim - This is often a sign that your alternator is failing and requires immediate service.
  • Stalling at traffic light - This is often a sign that your alternator is failing and requires immediate service.
  • Vehicle will not start - This is from the battery not having a strong enough charge or a failing starter.
  • Vehicle will not start in cold weather - This is usually an indication of a bad battery.

If you notice any of these symptoms or if you have any other concerns, come and see us immediately. Your car's electrical system should be inspected every two years or whenever serviced for any type of problem.
