Harrell’s Tire & Auto Service investigates vehicle electrical problems, including starting concerns, intermittent warning lights and accessories that stop working. Tell the advisor when the issue occurs, how long it lasts and whether it follows rain, a jump-start or recent repair work.
Testing the system, not just reading a code
Electrical diagnosis may involve checking the battery and charging system, connections, wiring, fuses, sensors or communication between control modules. A fault code is a starting point for testing; it does not prove that the named component needs replacement.
