Today’s vehicles depend on computers and electronics to keep them running reliably and safely. Some of the warning signs of electrical problems include: battery or electrical dashboard warning lights, headlights or taillights that are dim or operate intermittently, a burning plastic smell or blown fuses.

Because many electrical problems are caused by the vehicle’s battery, we often begin with a thorough visual inspection of the battery. Are the terminals corroded? Are the connections secure? We then test the battery to see if it can deliver adequate power, and recommend replacement if necessary. Other components that are included in a vehicle electrical inspection include the alternator, starter and electrical cables and harnesses.
