What do I need to know about the electrical system of my truck?

Your heavy truck's electrical system is kind of like the wiring in your home—it's essentially circuitry and wires running to the correct terminals. And they're all interconnected in such a way that if the battery powering your engine has any problems, your truck might not be able to move an inch.

How do I know when my trucks electrical system is failing?

While the following might not be signs of total failure, they could be signs that your electrical system is on the brink of failing:

  • Poor fuel economy
  • Uneven lighting
  • Flickering truck lights
  • Problems starting the vehicle
  • Failure of the truck to move
  • Blown fuses/tubes
  • The smell of burning wires

These issues are just the tip of the iceberg, and if left unchecked, they could get worse and lead to costly problems.

It could also be a hidden problem that only a highly skilled mechanic can find. We are your go-to experts for heavy truck electrical services in Denver, CO because we put our customers first every time and make sure we always get to the bottom of every issue. So if you think your truck's electrical system is failing and needs a quick diagnosis, don't hesitate to reach out to us.

What does it take for a trucks electrical system to be in "tip-top" condition?

If your electrical system checks the following boxes, you're good to go:

  • There should be no shortage of power or dimming lights, even during high usage
  • All wires should be visibly clear of burn marks

When your heavy truck is in the hands of the experts at JE-CO Truck & Trailer, we won't rest until we bring its electrical system to tip-top condition.

These guys were great! They are open 7 days/week, which is why I found them. They diagnosed and rebuilt the power divider on my 2000 Pete. G and the staff were excellent with their communication. They will be my first call if I ever need work done in the Denver area. Thanks Jeco!
