Of course, if sensor lights are lit now, make sure you visit our experts at Earnhardt Lexus for a service appointment right away.

Most people think of the battery as providing the power for their car to operate when in fact it is the alternator. The alternator converts mechanical energy into electrical energy allowing the car to charge the battery while you are driving. The starter works in a different way converting electrical energy of the auto into mechanical energy.

Both the alternator and starter can wear out over time needing repair or replacement. Keep an eye on symptoms as well as sensors.If you are having trouble with common electrical system problems, you can count on our well-trained mechanics. Pricing is right when you Dare to Compare.

WHAT IS THE ALTERNATOR

The alternator is located in the front left of the engine and begins working when the engine is started. Your car’s alternator is electronic and its primary function is charging the car battery while you drive. If the battery is dead, however, it cannot be charged by the alternator. The alternator regulates the electricity used to operate your vehicle by different components of your car allowing them to function.

Signs Of Possible Need For Alternator Repair:

  • ALT light turns on
  • Headlights and dashboard lights dim
  • Smell like burning rubber indicating a belt issue
  • Grinding noise coming from the engine
  • Starting issue with the engine

WHAT IS THE STARTER

The starter is located on the left side of the motor near the bottom. It is an electric motor which rotates and starts the engine. The system is made up of the motor attached to a solenoid which is an electronic device that takes the battery power and delivers it to the starter motor. It also pushes the starter gear allowing it to mesh with the gear teeth of the engine’s flywheel.

When starting your car, a high current is used. This requires a charged battery in order for the starter system to operate. If your car won’t start but the battery is charged, the starter is the most likely culprit.

Signs Of Possible Need For Starter Repair:

  • Clicking noise when engine should be starting
  • Dashboard lights come on but the engine will not start
  • Engine will not work after a jumpstart
