Battery, Alternator and Electrical System

We’ll get your Vehicle off to a Great Start

Your vehicle’s battery provides the initial charge needed to start your engine. Once your vehicle’s engine is running, the alternator kicks in to power the electrical system that includes the radio, lights, heater, air-con, infotainment system, horn and more. Having issues with any of your vehicle’s electrical accessories can indicate that you may have to replace the battery or you need to test and/or repair your alternator.

Symptoms to look out for:

  • Battery warning light is on
  • Accessories fail (radio, heater, dim lights, power windows, etc.)
  • Strange growling or whining noises
  • Regular stalling or difficulty starting

Do you believe you may be having problems with your battery, alternator or electrical system?

If you do, the GM Certified service experts at Roy Foss Thornhill can diagnose and repair electrical systems, replace your vehicle’s battery, test and repair alternators and plenty more.
