Batteries, Alternators, and Starters — The Core Trio
Most electrical issues stem from one of three key components: the battery, alternator, or starter.
Battery
If your battery is more than three years old or struggles to hold a charge, it might be time for replacement. We’ll test its voltage and cold-cranking amps to ensure reliability during Iowa’s cold winters.
Alternator
When your alternator fails, your car might still run — but not for long. A weak alternator won’t recharge the battery or power accessories correctly, leading to dim lights, weak electronics, or stalling.
Starter
A clicking noise or slow engine crank often means your starter is failing. We can test and replace starters quickly so your vehicle starts smoothly again.
By addressing all three components, we make sure your electrical system runs like new.
Preventive Electrical Maintenance
Electrical problems don’t always appear overnight. Regular maintenance can help prevent unexpected failures and costly repairs down the road.
To keep your system running smoothly, we recommend:
-
Inspecting battery terminals and cables for corrosion
-
Testing your battery every six months
-
Replacing the battery every 3–5 years
-
Checking your alternator output during routine maintenance
-
Watching for any dimming or flickering lights
-
Ensuring your car’s software and sensors are updated
Small checks now can prevent major issues later — especially as vehicles rely more heavily on electronics each year.
Hybrid and EV Electrical Systems
Electric and hybrid vehicles come with additional electrical demands. Our technicians are trained and equipped to handle high-voltage systems safely and effectively. Whether it’s a battery cooling issue or regenerative braking fault, we’re ready to help.
We understand the unique challenges of servicing these vehicles and provide the same quality and care as we do with traditional gasoline models.
