Solving ComplexElectrical Issues with Precision and Care
Modern vehicles depend on a complex network of electronics, and when something fails, you need a repair shop that can diagnose the issue accurately, not just guess. At Cain and Sons’ Automotive, our ASE Master Certified technicians use factory-grade diagnostic tools to uncover and resolve electrical problems with precision.
From dead batteries and faulty alternators to hard-to-find wiring issues, we deliver clear answers and lasting solutions. We don’t just swap parts we take the time to pinpoint the problem, walk you through the findings, and perform repairs with the same care we’d give our own family’s vehicle.
Since 2007, drivers throughout Glen Rock have turned to our family-owned shop for trusted diagnostics and reliable electrical repairs on Domestic and Asian makes alike.

What You Can Expect From Our Electrical Repair Service
Battery & Charging Tests
We test battery health, alternator output, and voltage regulation using multimeters and diagnostics. If your battery keeps dying or your car struggles to start, we identify the cause, whether it’s the battery, alternator, or a parasitic draw, and fix it fast.
Starter & Ignition Testing
The engine won’t crank or start inconsistently? We inspect ignition switches, starter motors, relays, solenoids, and wiring continuity to zero in on the issue and get your vehicle starting reliably again.
Circuit Testing & Wiring Repair
Using Snap-On and Autel diagnostic scanners, we identify issues like damaged wires, melted connectors, or ground faults through thorough diagnostics. Once the problem is diagnosed, our technicians use specialized tools to repair or replace the affected wiring, restoring proper electrical flow and ensuring your vehicle's electrical systems function as intended.
Module & Sensor Diagnostics
We scan and test faulty modules or sensors causing warning lights or performance issues. Components are verified, replaced with OEM-grade parts, and reprogrammed if necessary to ensure long-term reliability.
Power Accessory Repair
From stuck windows to unresponsive locks, we diagnose and repair failed motors, switches, and modules so your accessories work smoothly again.
Fuse & Relay Replacement
Blown fuse? We go deeper. We identify the root cause, like shorts or overloads, and replace any faulty fuses, relays, or wiring to prevent it from happening again.
Lighting System Repair
We restore lighting performance by testing and fixing bulb sockets, control modules, and ground connections, keeping your headlights, signals, and brake lights shining bright.
