Charging Systems

If you’re having a problem starting your car, it could be the battery, starter, alternator or another component of your starting and charging system. It’s important to inspect each one of them before you begin replacing parts. Whether you choose to diagnose your parts yourself or bring it to us, Complete Auto Repair Rochester, MN is here to help you find out what’s wrong, so you can do the job right the first time.

In addition to the car battery, there are two other major components to your vehicle’s starting and charging system. And these two components must be in good working order for your vehicle to start and run properly.

Starter — when you turn the ignition key, you are actually turning on the starter, which then cranks the engine. When a starter isn’t working correctly, the engine may start with great difficulty, or not at all. Starter problems may be due to electrical/mechanical failure or outright breakage.

Alternator — the alternator carries out two important tasks. It recharges your battery while the vehicle is running to keep it at peak starting power. The alternator also works with your battery as a team to operate electrical components, such as headlights, windshield wipers, and more. A malfunctioning alternator can cause electrical components to operate erratically, or even cause your engine to suddenly stop running.

If you experience battery trouble, there are a couple of things you may want to check before calling for service.

Be sure the battery is properly secured. Vibration caused by an unsecured battery can affect battery life.

The cables to the battery terminals must be clean and tightly connected. Buildup of corrosive elements on the terminals can seriously weaken starting power. Be sure the side terminals aren’t over-tightened as well.
