Starting the engine is arguably the most important function of a vehicle’s electrical system. To accomplish this, the starting system converts electrical energy from the battery to mechanical energy through a starting motor. A starter is composed of an electric motor that drives a pinion gear designed to engage with the engine’s flywheel. When the ignition switch is turned, the starter cranks the engine using this mechanical energy. Overtime, the battery’s cables can become corroded or loose, causing slow cranking, arcing at cable connections, and other electrical system problems. To prevent this and to ensure good starter perfomance, Auto Care Experts recommends checking the battery cables at every oil change. Another starter issue occurs when the pinion gear that meets with the engine’s flywheel becomes worn. When this happens, the engine will not reach the necessary cranking speed and will not start. As an added measure of protection, we recommend that you have your alternator tested prior to any long car trips.
