What is a Starter?

A starter is a crucial component of your vehicle's engine system. Its primary function is to initiate the internal combustion process by cranking the engine. When you turn the ignition key, the starter motor engages with the engine's flywheel or flexplate, causing the engine to turn over. This turning motion starts the combustion process, allowing your engine to run. Starters are typically electric motors that require a sufficient amount of power to operate effectively.

What is an Alternator?

An alternator is another essential component of your vehicle's electrical system. While the engine is running, the alternator generates electrical power to charge the battery and supply power to various electrical systems and components. It converts mechanical energy from the engine's rotation into electrical energy, ensuring that the battery remains charged and the electrical system functions properly. Without a functioning alternator, your vehicle's battery could quickly lose its charge, leading to issues with starting the engine and operating electrical components.

How Do You Know if Your Starter is Bad or Your Alternator?

Diagnosing whether your starter or alternator is faulty can sometimes be challenging, as they exhibit different symptoms. If your vehicle doesn't crank or makes a clicking sound when you turn the ignition on, it could be a sign of a bad starter. On the other hand, if you notice dimming lights, a dead battery, or a warning light on your dashboard indicating a charging issue while the engine is running, your alternator might be failing.

How Much Do Starters and Alternators Cost?

The cost of starters and alternators can vary based on factors such as the make and model of your vehicle, the brand of the replacement part, and whether you're buying an original equipment manufacturer (OEM) or aftermarket component. Generally, aftermarket starters and alternators can range from $50 to $300 or more. OEM parts tend to be more expensive, with costs ranging from $100 to $500 or higher. Labor costs for installation may also vary depending on the complexity of the repair and your location. It's advisable to consult with a professional mechanic or parts specialist to get accurate pricing for your specific vehicle.
