Auto electricians specialise in vehicle electrical systems — wiring, sensors, batteries, alternators, and electronic modules — which most general mechanics don’t diagnose in depth. M&J Auto Electrics focuses exclusively on electrical work, so faults get found faster and fixed correctly the first time.
Common signs include a warning light on your dash, a car that won’t start or starts intermittently, flickering lights, or a battery that keeps going flat. If any of these happen, a diagnostic check starting at $50 will identify the cause.
A check engine light means your vehicle’s computer has logged a fault code — it could be anything from a faulty sensor to an emissions issue. A diagnostic scan will read the exact code and tell you what needs fixing.
