ELECTRONIC IGNITION

The battery stores electrical energy and the starter converts that energy into mechanical force to turn the engine for starting. The alternator produces electric current to replace what the starter used during start-up and to support electrical loads when the engine is running. An ignition module turns the low-voltage supply to the ignition coil on and off and the coil produces the high voltage for the ignition systems. This creates a spark at the spark plugs and ignites the air/fuel mixture in the engine. A belt transmits power from the front of the engine to the alternator’s pulley along with other accessories.

Driving habits such as frequent on/off cycles will cause more wear on the starter than a simple daily commute to work. Other factors that will cause wear include:

• Extreme weather conditions
• The mileage on your vehicle
• The age of your vehicle
• Excessive electrical draws like in-vehicle entertainment systems

Some of the symptoms of a problem with your electronic ignition include:

• Headlights and interior lights dim
• Your vehicle’s “Check Engine” or battery light is illuminated
• Some of your vehicle’s accessories fail

If you are experiencing any of the symptoms listed above an Express Oil Change & Tire Engineers® technician can quickly and accurately diagnose your problem.
