Complete Auto Electrical Services

Modern vehicles are rolling computers. When the electrical system falters, nothing else matters. We diagnose and repair it all.

Electrical Diagnostics

Advanced scan tools and multimeter testing to pinpoint electrical faults — from parasitic drains to intermittent wiring issues that other shops miss.

Battery & Charging

Battery testing, replacement, and charging system repairs. If your car won't start or the alternator is failing, we'll get it sorted fast.

Wiring & Harness Repair

Damaged, frayed, or corroded wiring? We repair and rewire harnesses, fix short circuits, and restore proper electrical continuity.

Dashboard & Lights

Flickering dash lights, blown fuses, faulty sensors, or exterior lighting failures — we diagnose and replace defective components.

ECU & Computer Systems

Check engine lights, ECU troubleshooting, and module programming. We read codes, interpret data, and fix the root cause — not just the symptom.

Starters & Alternators

Starter motor replacement, alternator repair, and ignition system diagnostics. No more clicking sounds or power loss while driving.
