Car Electric Repair

Watch for these warning signs: Difficulty starting or slow cranking when turning the key, dimming or flickering headlights and interior lights, battery warning light illuminated on dashboard, electrical accessories not working (windows, locks, radio), burning smell or visible smoke from wiring, fuses blowing repeatedly, battery dying overnight or after short periods, warning lights that stay on or come on intermittently, and erratic behavior from gauges or displays. If you notice any of these symptoms, it's important to have the electrical system inspected promptly to prevent further damage or being stranded.

Repeated battery drain is typically caused by: Parasitic draw — something is staying on when the car is off (interior lights, modules not sleeping properly, aftermarket accessories). Failing alternator — not charging the battery properly while driving. Old or worn battery — unable to hold a charge. Corroded or loose battery connections — preventing proper charging. Short circuits — wiring faults draining power. Faulty voltage regulator — overcharging or undercharging the battery. Our electrical diagnostic service includes parasitic draw testing to identify exactly what's draining your battery, along with charging system and battery health testing.

Alternator failure symptoms include: Battery warning light on the dashboard, dimming lights that brighten when revving the engine, dead battery despite recent replacement, whining or grinding noise from the alternator area, electrical accessories working poorly or intermittently, smell of burning rubber or hot wires near the alternator, and vehicle stalling or difficulty restarting. A failing alternator won't charge the battery, eventually leaving you stranded. We can test your charging system to confirm alternator condition and determine whether repair or replacement is needed.

Many wiring issues can be repaired without full harness replacement. Our approach: Minor damage — individual wires can be spliced using proper techniques and weatherproof connectors. Connector issues — damaged pins can be replaced or connectors repaired. Localized corrosion — affected sections can be cut out and repaired. Chafed wiring — protective loom can be applied after repair. However, complete harness replacement is recommended when: damage is extensive throughout the harness, multiple failures indicate widespread deterioration, or the cost of repair approaches replacement cost. We always assess the full extent of damage and recommend the most practical solution.

The check engine light can indicate many issues, both electrical and mechanical: Sensor failures — oxygen sensors, mass airflow sensor, throttle position sensor. Emission system problems — catalytic converter, EVAP system leaks. Ignition issues — spark plugs, coil packs, ignition control module. Engine management — ECU communication errors, software glitches. Wiring problems — damaged sensor wires, poor connections. Our diagnostic scan reads the specific fault codes stored in your vehicle's computer, and our systematic testing determines the exact cause — whether it's a faulty part, wiring issue, or software problem.

Diagnosis time varies by complexity: Simple issues (blown fuse, dead battery): 30 minutes to 1 hour. Moderate problems (sensor replacement, starter issues): 1-2 hours. Complex electrical faults (intermittent problems, wiring shorts): 2-4+ hours. Intermittent issues that don't occur on demand: May require extended testing. Electrical diagnosis often takes longer than mechanical diagnosis because we must systematically trace circuits, test components, and verify findings. Rushing this process leads to misdiagnosis and repeated repairs. We provide diagnosis time estimates upfront and keep you informed throughout the process.

Yes, electrical issues are a leading cause of no-start conditions: Dead or weak battery — insufficient power to crank the engine. Faulty starter motor — won't engage or turn the engine over. Corroded connections — preventing power flow to starter. Bad ignition switch — not sending signal to start the car. Failed fuel pump relay — no power to fuel pump. Faulty crankshaft position sensor — engine won't recognize crank signal. Immobilizer issues — security system preventing start. Anti-theft system malfunction — thinking the car is being stolen. Our systematic approach quickly identifies which component in the starting circuit is at fault.

Parasitic drain is when something draws power from your battery while the vehicle is off. Normal drain is about 25-50 milliamps for modules that stay powered. Excessive drain (over 50-100mA) can flatten your battery overnight. To find the source, we: Connect a sensitive ammeter to measure current draw, wait for all modules to enter sleep mode (can take 30+ minutes on modern cars), systematically remove fuses to isolate the circuit causing the drain, and test individual components on that circuit to find the faulty item. Common culprits include: interior lights, trunk lights, aftermarket accessories, faulty door switches, entertainment systems, and malfunctioning control modules.

Electrical repair costs vary significantly by issue: Basic repairs (fuse replacement, bulb replacement): AED 50-150. Battery replacement: AED 300-800 depending on vehicle. Alternator replacement: AED 600-1,500. Starter motor replacement: AED 500-1,200. Sensor replacement: AED 200-800 per sensor. Wiring repair: AED 200-1,000+ depending on extent. Module replacement: AED 800-3,000+ depending on module. Diagnostic testing: AED 150-350 (often applied to repair cost). Luxury and European vehicles typically cost more due to complex systems and parts pricing. We provide detailed quotes after diagnosis so you know exactly what to expect.

Yes, we provide professional installation of aftermarket electrical accessories including: LED lighting upgrades and auxiliary lights, aftermarket stereo and speaker systems, parking sensors and backup cameras, dashcams and security cameras, remote start systems, alarm and security systems, USB charging ports, and auxiliary power outlets. Professional installation is crucial — improper wiring can cause electrical fires, battery drain, or damage to factory systems. We use proper techniques including: appropriate wire gauges, fused circuits, weatherproof connections, and correct integration with factory systems. This ensures reliability and protects your vehicle.
