Why Batteries, Starters and Alternators are important

Batteries, Starters and Alternators are three interrelated components of a vehicle. These three are collectively called your car’s electric system. Batteries provide the necessary power for the engine to start up, and then the alternator uses that energy as electric current to keep the car running. It’s easy to spot when you have electrical problems when one of these won’t work properly.

You know you need to have these three checked when:


It takes longer for the engine to start or it does not start at all. A car’s battery provides the electrical current for the entire car, until then everything should be running smoothly.


Although, car batteries supply electric current to the entire vehicle, the starter is responsible in triggering the engines. They send out spark or ignite the engines that get the whole vehicle running. This makes it imperative for the car starter to function smoothly.

It is hard to detect when car starters will fail. Here at Ed Cain’s Auto Service, we perform tests to ensure that your car starters should never fail you.


While the battery is responsible for the engine to power up and the starters to run the engine, alternators ensure that your vehicle runs smoothly and continually until you voluntarily stop it. You know you have an alternator problem when your car starts but eventually loses power.

Other warning signs:

  • the “Check engine” light or battery light is turned on
  • Lights (interior light and headlights) are blurry or dim
  • Other car accessories do not function properly
