Electrical System Diagnostics

When your vehicle struggles to start, loses power, or shows warning lights, the issue is often electrical. At Parker Automotive & Diesel in Moncks Corner, we provide professional electrical system diagnostics for cars, trucks, and diesel vehicles across Berkeley County and the Lowcountry.

Our technicians use advanced diagnostic tools to test batteries, alternators, starters, wiring, and sensors. We also check connections and your vehicle’s onboard computer to uncover hidden issues that generic scanners may miss. From a weak battery to a failing alternator or complex wiring fault, we pinpoint the problem quickly and accurately.

Because modern vehicles rely heavily on electronics, electrical problems can lead to bigger failures if left unchecked. Our team provides a clear explanation of the issue and honest repair recommendations, so you can get back on the road with confidence.
