Understanding Your Electrical System
The Battery
Your vehicle's primary power source. It provides the initial surge of electrical energy needed to engage the starter and powers electronics when the engine is off.
The Starter
The mechanical bridge between electrical power and engine combustion. It converts battery current into physical rotation to crank the engine to life.
The Alternator
The generator that takes over once the engine is running. It recharges the battery and supplies electricity to all on-board systems during operation.
