Reliable Solutions for Complex Wiring Problems

Book Electrical Repair in Midland

Your truck won't start, the gauges flicker randomly, or the charging system fails without warning. These symptoms point to wiring faults, shorts, or sensor failures that demand precision and technical skill. Lonewolf Diesel specializes in diagnosing complex diesel and equipment electrical systems across Midland, where oilfield vibration and extreme heat routinely damage wiring harnesses and connectors. You'll watch our technicians trace circuits with multimeters, checking voltage drops and continuity until the exact fault is isolated.


We handle alternators, batteries, starters, harness repairs, and module testing with dealership-quality results but without dealership pricing. Our team is trained on the unique electrical demands of heavy-duty vehicles operating in harsh conditions. Each repair is built to last, using high-quality components and correct installation techniques that withstand the rigors of daily use.

How Our Process Works

You bring your vehicle to our shop where we begin with a visual inspection of battery terminals, ground connections, and exposed wiring. We then use diagnostic tools to measure charging voltage, starter draw, and circuit resistance. This step-by-step approach helps us pinpoint whether the problem originates in the power source, the wiring itself, or a malfunctioning component.


Lonewolf Diesel follows manufacturer wiring diagrams and OEM specifications during every repair. Technicians trained on complex diesel and equipment electrical systems understand how vibration and heat cause wiring failures. We replace damaged sections, repair corroded terminals, and secure harnesses to prevent future movement and wear.


Once repairs are complete, we test the entire system under load to confirm proper operation. This includes verifying that alternators maintain correct voltage, starters engage smoothly, and all sensors communicate accurately with the vehicle's computer. You leave with a system that performs reliably, even under demanding conditions.

What's Included in This Service?

Electrical problems can be frustrating and difficult to trace without the right tools and training. Here are answers to questions we hear most often about our electrical repair services.

What causes most electrical failures in this area?
Vibration from rough roads and extreme heat in the oilfield environment are the leading causes. These conditions loosen connections, crack insulation, and corrode terminals over time.
How do you diagnose intermittent electrical issues?
We use multimeters and specialized test lights to check circuits while simulating road conditions. This helps us recreate the fault and identify loose connections or damaged wires that only fail under movement or heat.
Can you repair wiring harnesses, or do they need replacement?
Many harnesses can be repaired by replacing damaged sections and re-soldering connections. We only recommend full replacement when the harness is extensively corroded or damaged beyond safe repair.
Do you work on both diesel and gas vehicle electrical systems?
Yes, our technicians are trained on both, with extensive experience in the heavier electrical loads and more complex wiring found in diesel trucks and equipment.
How long do electrical repairs typically take?
Simple repairs like alternator or battery replacement take a few hours. Complex wiring diagnostics and harness repairs may require a full day, depending on the severity and location of the fault.

Electrical problems don't fix themselves, and delays often lead to bigger failures that leave you stranded. Our team provides accurate, safe, and long-lasting repairs that restore full function to your vehicle's electrical system. Reach out today and let us solve your wiring, charging, or sensor issues with the precision your truck deserves.
