Today’s heavy-duty diesel engines are notably more reliable than their ancestors, and with that comes an increase in complexity.  Their elaborate electrical systems require regular maintenance and service in order to ensure the best performance.  When your truck develops an issue, you need to have a trustworthy shop that you can rely on to have it diagnosed, serviced and repaired quickly so you can get back on the road and back to work. 

The diagnosis and repair of electrical problems is possibly the most time-consuming and difficult form of vehicle diagnosis. The electronic control units (ECU) in diesel trucks give diagnostic technicians access to sensors located throughout the engine compartment that provide performance data on various components. However, with many electrical systems, and connections buried deep under the seats, carpet, dash, and body panels of your truck, electrical problems require a great deal of knowledge, experience, and patience to locate and repair. Not to mention, modern, up-to-date technologies and diagnostic equipment. Our tech-savvy, educated and experienced technicians are able to use computer diagnostic systems to locate and target the exact cause of engine or vehicle failure with spot-on accuracy. Not only do you get quick diagnostics, but our systems also save you money that you may have otherwise spent on unnecessary assessments and repairs. 

Indicators of electrical issues

The number one indicator of an electrical issue will be a light (or array of lights) on your dashboard.  Beyond that, there are some other signs you may notice which could be your truck telling you there’s an electrical problem:

  • Damaged or failed battery
  • Dull headlights or brake lights
  • Faulty or discoloured wiring
  • The smell of burnt plastic
  • Faulty or discoloured wiring
  • Inability to start your engine
