Mobile mechanic performing diagnostics and electrical repairs on truck in Kilgore, Texas

At Top Flight, our team of licensed technicians is equipped with the latest software and tools to diagnose and resolve any electrical troubles your heavy-duty truck may experience. From assessing diagnostics systems to tackling the toughest electrical issues, we've got you covered. But we don't just stop there - we guarantee that your truck’s electrical network operates at peak performance with the best maintenance services. Rest assured, we thoroughly inspect every connection and component, eliminating potential short circuits or overloads.

Here are two telltale signs of electrical systems complications in heavy-duty trucks.

Failing Circuit Protectors

Your truck integrates safety features such as fuses and circuit protectors, which act like a gatekeeper for the flow of electricity. These keep electrical issues at bay and defend against power surges. However, if they start to malfunction, it can cause a domino effect of damage throughout the system. Not only that, but a malfunctioning circuit protector may fail to activate during a power surge, leaving your truck vulnerable to electrical problems. We routinely check and replace your circuit protectors to ensure your heavy-duty truck’s optimal performance.

Defective Starter Motor

Your heavy-duty truck’s electric starter motor is the heart of its electrical system, pumping life into the diesel engine. If you hear clicking and grinding sounds upon ignition, or if the engine fails to start despite the motor engaging, your starter motor is likely facing issues. These could appear as minor wear and tear or severe issues such as incorrect installation that damage the motor's inner workings, such as its magnetic brushes.

Gary Roberts

Ram 5500 blew out drivers side front wheel bearing thankfully in Kilgore on a 3000 mile x country work trip. Chose Top Flight. They sent out a wrecker on Sunday evening, took my truck in, and I put up at nearby hotel. Called first thing in the am with parts list and had my truck repaired in a few hours. I was back on the road to home. Excellent service, repairs, and value. I enjoyed your company, to include the wrecker service who dropped me at my hotel. Keep it up!
