Truck Diagnostics & Electrical Repair Service in Edmonton, AB

At Heavy Hauler Service and Repair, we specialize in finding solutions for complex, hard-to-diagnose problems. Your vehicle has several systems to alert you to issues, but there are a few warning signs that you should look for, and if found, address immediately:

  • Your engine fails to start.
  • Your battery is damaged, bloated, or dies.
  • Your headlights or brake lights are dull or dim.
  • You notice the smell of burnt plastic or wiring.
  • You see cracked, worn, or discoloured wiring.

Diagnosing and fixing electrical issues can be tricky, but our engine diagnostics experts recognize that it is vital to diagnose and repair electrical problems quickly and efficiently. We are committed to saving you time and money and understand that every day your truck is not available, you are not benefiting from the revenue generated by your vehicle.


One of the first signs of an issue with your truck is typically a check engine light. The cause of a check engine light can be something as simple as a loose or faulty gas cap or a more severe issue such as a bad catalytic converter. While the check engine light may come on for various reasons, it is an indication that your vehicle has a problem that needs immediate attention.

Whatever the cause, it's best not to take the chance of causing significant damage. Our technicians have the training, skill, and advanced equipment to determine the problem quickly. Our team has seen, diagnosed, and repaired just about anything that can go wrong with any type of truck engine.

Additionally, we have the necessary software to adjust parameters in all engines. If you have an engine light on, or your truck just doesn't seem to be running the way it should, let us conduct a diagnostic test to determine the problem. Diagnostics can reveal issues in your truck's engine, transmission, exhaust system, brakes, and other major components, and our mechanics can also improve the performance of your truck.

I chose Heavy Hauler because they were close to my shop. However, I continue to use their services because of their excellent service and workmanship. Derek, Luke, and the gang are great to deal with. I highly recommend them.
