Professional Auto Electrical Solutions For All Types of Vehicles
A vehicle’s electrical system controls ignition, lighting, power accessories, and engine performance. Our expert technicians diagnose and repair battery, alternator, wiring, ECU, and sensor issues for cars, trucks, SUVs, hybrids, and EVs to ensure peak performance.
Battery Testing & Replacement
A weak or failing battery can cause starting issues, voltage drops, and power loss. We test cold-cranking amps (CCA), voltage output, and charging capacity to determine if a replacement is needed. High-quality OEM and AGM batteries ensure reliable performance in all conditions.
Alternator & Starter Motor Repair
The alternator powers the electrical system, while the starter engages the engine. We repair failing alternator diodes, worn brushes, and voltage regulator faults. Starter issues like solenoid failure, worn pinion gears, or faulty ignition relays are diagnosed and fixed efficiently.
Wiring & Fuse Repairs
Electrical faults often stem from corroded wiring, short circuits, blown fuses, or melted insulation. We locate and repair high-resistance connections, faulty grounding points, and power distribution failures to restore full electrical functionality and prevent voltage spikes.
Sensor & ECU Diagnostics
A failing oxygen sensor, mass airflow sensor, crankshaft position sensor, or throttle position sensor can trigger the check engine light and reduce fuel efficiency. Using OBD-II scanning, waveform analysis, and ECU reprogramming, we ensure precise engine and transmission control.
Power Windows & Door Locks Repair
Electrical issues in window motors, regulators, or door lock actuators can prevent smooth operation. We troubleshoot relay failures, wiring shorts, and switch malfunctions to restore full functionality. Key fob programming and central locking system repairs are also
Hybrid & EV Electrical Service
Hybrid and electric vehicles (EVs) rely on high-voltage battery systems, regenerative braking circuits, and inverter modules. We handle battery pack diagnostics, inverter recalibration, and hybrid drive system troubleshooting to maintain efficiency and range.
Lighting System Repairs
Dimming or flickering headlights, taillights, and brake lights indicate faulty wiring, weak relays, or failing bulbs. We repair LED, halogen, and HID lighting systems, ensuring proper illumination. Turn signal and dashboard instrument cluster issues are also addressed.
Warning Signs of Electrical Issues in Your Vehicle
A failing electrical system can cause ignition problems, power loss, and malfunctioning accessories. Recognizing early warning signs can prevent costly repairs and keep your vehicle running safely.
Dashboard Warning Lights
A battery light, check engine light, or ABS warning may signal charging system failure, sensor malfunctions, or ECU communication errors. Ignoring these alerts can lead to voltage drops, poor fuel efficiency, or engine misfires.
Dimming or Flickering Lights
Fluctuating headlights, interior lights, or instrument clusters indicate alternator issues, weak battery output, or corroded wiring. Faulty relays, fuses, or poor grounding connections can cause inconsistent voltage supply to lighting systems.
Engine Starting Issues
Slow cranking or clicking sounds when turning the key suggest starter solenoid failure, weak battery voltage, or faulty ignition switches. A failing neutral safety switch or fuel injection relay can also prevent the engine from starting.
Electrical Accessory Failures
Non-functioning power windows, door locks, radio, or climate controls often result from worn wiring harnesses, blown fuses, or defective control modules. Weak alternator output can also affect infotainment and electronic steering components.
Unusual Smells or Burning Odors
A burning plastic or sulfur-like odor may indicate overheated wiring, melting insulation, or a short circuit. Common causes include fuse box failures, overloaded circuits, or alternator diode overheating, which can lead to electrical fires if not addressed.
