We track down shorts, opens, and failing components so your truck and trailer work the way they should.
Why Choose Us
Tracing Electrical Problems to the Source
Electrical issues can be frustrating because the symptom often shows up far from the actual cause. Our ASE certified mechanics use wiring diagrams and methodical testing to follow each circuit until the fault is found. We repair the damaged section properly and protect it from moisture and vibration, so the problem doesn't come back. With 25 years of experience on trucks and trailers, we've seen just about every electrical gremlin a rig can have.
What We Offer
From Headlights to Charging Systems, We've Got It Covered
Modern trucks rely on electrical power for lighting, starting, engine control, and safety systems. We repair the circuits and components that keep all of it running. Here's what our electrical repair service includes:
Wiring Harness Repair: Chafed, melted, or corroded wiring can cause shorts and intermittent failures. We repair or replace damaged sections and secure them to prevent future wear.
Truck and Trailer Lighting Repair: Burned-out lights and flickering lamps are common inspection violations. We fix headlights, marker lights, brake lights, and turn signals on both truck and trailer.
Trailer Plug and Connector Repair: A worn or corroded 7-way plug can cut power to your trailer lights and ABS. We clean, repair, or replace connectors for a reliable connection.
Alternator and Charging System Repair: If your batteries keep running low, the charging system may not be keeping up. We test and replace alternators, regulators, and charging cables.
Starter and Starting Circuit Repair: Clicking, slow cranking, or no-start problems can come from the starter or its wiring. We diagnose the circuit and repair the part that's causing the trouble.
Ground Connection Repair: Poor grounds cause dim lights, strange gauge readings, and random electrical faults. We clean and restore ground connections throughout the truck.
Fuse, Relay, and Power Distribution Repair: Blown fuses and failed relays can shut down important systems. We find out why they failed and fix the underlying problem.
Dash, Gauge, and Switch Repair: Faulty gauges and switches make it hard to monitor your truck. We repair dash electrical problems so you have accurate readings and working controls.
Frequently Asked Questions
Why do my truck lights keep burning out?
Frequent bulb failures can be caused by voltage spikes, a faulty charging system, loose connections, or vibration damage. We test the system to find why lights aren't lasting.
Why do my trailer lights work sometimes but not others?
Intermittent trailer lighting is often caused by a corroded 7-way plug, a damaged pigtail cable, or a bad ground. These problems usually get worse over time.
Can electrical problems cause my truck not to start?
Yes. A weak battery, bad starter, corroded cables, or poor grounds can all prevent your truck from starting. We test the full starting system to pinpoint the issue.
What causes random electrical problems in a truck?
Loose or corroded connections, damaged wiring, and poor grounds are the most common causes. Moisture and vibration can make these problems come and go.
