Electrical & Wiring Services
Professional Automotive Electrical Diagnostics & Wiring Repair
Modern and classic vehicles rely on properly designed and maintained electrical systems. From power delivery to signal communication, wiring integrity directly affects engine operation, transmission control, safety systems, and drivability.
We provide professional automotive electrical diagnostics, wiring repair, and system reconstruction for classic cars, modern vehicles, and restomod projects.
Common Electrical & Wiring Problems
We routinely diagnose issues such as:
-
No-start or intermittent starting conditions
-
Loss of power or ground circuits
-
Blown fuses with no obvious cause
-
Instrument cluster and gauge malfunctions
-
Gear selector and transmission signal failures
-
CAN / LIN communication errors
-
Random warning lights or “ghost faults”
-
Voltage drops and parasitic battery drains
-
Damage caused by previous improper repairs
Electrical faults often originate from corroded connectors, broken conductors, poor grounding, incorrect splices, or degraded insulation.
