How the Systems Work

The starting system is a critical part of any car repair and includes a battery, starter motor, solenoid, ignition switch and in some cases a starter relay. An inhibitor (neutral safety switch) is included in the starting system to prevent the engine from being started if the vehicle is in gear and should also be inspected during any auto service.

When the car ignition switch is turned to start position, the battery provides current to the starter through the relay and solenoid. The car's starter engages a gear to a flywheel gear on the back of the engine and turns the engine over. The battery also supplies current to the ignition system which supplies spark to the plugs and ignites the fuel which causes the engine to start.

Your car's charging system includes an alternator (generator), drive belt, battery, voltage regulator and the associated wiring. After the engine is started and running, the alternator takes over as the source of power and the battery becomes part of the load on the charging system. The alternator supplies current back into the battery to keep the battery charged.

All the components are connected; a problem with one component can affect another component in the system and make the diagnosis of your cars problem more difficult.  For example: an alternator that is defective and over charging can damage the battery.  All of these items are critical your your car's performance and must be thoroughly checked during any auto service.

Testing and Servicing

Auto Service Experts technicians are trained to test your car's battery, charging and starting systems to give you an accurate diagnosis for repair. This diagnostic service provides a quick, accurate and comprehensive analysis of your car's critical electrical systems and is necessary prior to any auto repair.

The Service Includes:

  • Inspecting the car's battery, cables, case and hold down bracket
  • Testing the surface charge and cold cranking amp capacity of your battery
  • Testing the voltage draw of your starter
  • Testing the voltage output of your alternator
  • Clean your vehicle's battery terminals and connectors

  • Your car's starting system is ready to go when you are
  • Find a component problem before it can damage another component on your car, thus saving you money
  • Improve your car's reliability and performance
