  • Where to seek fleet electrical services in Texas¬†

Diesel Truck Battery Problems

Diesel truck engines require a lot of power to get started, which is why they typically have two batteries. If you ever replace a diesel truck battery, you should replace both at the same time. While this may be expensive, it’s recommended for the best care. Most automotive batteries last three to five years, but they can last much longer than that, especially with the right maintenance.

If you suspect your diesel truck battery has a problem, it could be related to your alternator. Test your alternator’s charging rate using a voltmeter. The voltage should be around 12. Anything lower than that means there is likely an issue. You should also check the connections to ensure no corrosion is present. Corrosion has the ability to prevent a solid connection, preventing the vehicle from starting.

Bad Wiring Harness

The wiring harness is a hub for a variety of connections, wires, and terminals that run throughout your 18-wheelers, semi-trucks, flatbed trucks, and any other fleet trucks you may have. With so many components in one area of your truck, there are bound to be problems.

Some bad wiring harness symptoms include:

  • Lower speeds shut off the engine
  • Problems starting the truck
  • Battery terminal corrosion
  • Connector damage
  • Other electrical and lighting issues

If you believe in having a bad wiring harness and your fleet truck has any of the above symptoms, find a Texas electrical mechanic sooner than later. An expert like the electrical mechanics at Carlos Truck Electric will be able to help diagnose the issue and provide long-lasting solutions.

Rewiring a Truck

Regardless of the maintenance and care you’ve put into your fleet trucks, aging and corrosion will always come naturally. It’s a major part of owning any vehicle. As your 18-wheelers, flatbed trucks, or diesel trucks age, their parts corrode naturally. Eventually, your wiring will reach a point where it requires a complete replacement.

Rewiring a truck shouldn’t be handled by an amateur or a novice electrical mechanic in Texas. Instead, it should be done by an expert with comprehensive knowledge of fleet electrical services.
