Comprehensive Auto Electrical Repair & Maintenance Services

Our team takes a detailed, hands‑on approach to every part of your vehicle’s electrical system. We focus on accurate diagnostics and efficient repairs to get you back on the road as quickly as possible.

Alternator

The alternator is responsible for keeping your battery charged and powering your vehicle’s electrical systems. When it starts to fail, you may notice dimming headlights, warning lights on the dashboard, or even unusual noises. We perform complete alternator testing using professional diagnostic equipment to accurately identify the problem.

If replacement is needed, we’ve got you covered. Our alternator service includes system voltage testing, belt inspection and replacement when necessary, checking all wiring and connections, and a full evaluation of the charging system. Most alternator repairs can be completed in just a few hours, and we always recheck the system afterward to confirm everything is working properly. All replacement alternators are backed by a warranty for added peace of mind.

Battery Replacement

Your car battery starts and powers electronics when the engine’s off. You’ll usually get 3-5 years out of a battery.

Signs that you’re about to have a dead battery include:

Slow cranking when you start the car
Random electrical gremlins
Dashboard warning lights
Swollen battery case
Corroded terminals

We stock top batteries for all kinds of vehicles. Our battery service includes:

Testing your system before we swap anything
Disposing of your old battery properly
Cleaning and protecting the terminals
Checking the charging system

We make sure your new battery’s secure and connected right. That way, you avoid vibration damage and annoying electrical issues down the road.

Starter

The starter motor gets your engine turning when you turn the key. If it fails, even a good battery won’t help—you’re not going anywhere.

Common starter issues:

Clicking but no engine turnover
Grinding noises when starting
Starts sometimes, not others
Starter stays engaged after the car starts

We start with a full check of the starting system—motor, solenoid, and all the wiring. If you need a new starter, we’ve got you covered.

Most installations are done in a couple of hours, depending on your car. We double-check everything after the repair to make sure you’re set.

Other Vehicle Electrical System Services

We do more than just the basics. If it’s an electrical component we can fix it.

Dashboard lights, dome lights, whatever

"No funny quotes with hidden agenda or hidden charges; no withholding of information to steal your business. Helped revive and bring our old is gold Honda and an Audi into almost brand new: rode like butter with no spurious or funny sounds. Will happily ditch the authorized service centers for Cal at Car clinic."
