Electrical problems are a leading cause of work interruptions and costly repairs, if not irreparable damage. While there are numerous causes behind electrical issues, the good news is there are also warning signs. Knowing what to look out for will help prevent any related truck electrical issues from escalating before you can repair them.
Here are some signs of electrical issues that need semi-truck electrical repairs sooner than later:
Check the Engine Control Unit
The Engine Control Unit (ECU) is responsible for regulating fuel injection and ignition timing for the engine. It’s also in control of monitoring the engine’s sensors and the emission control systems. As an essential part of a working semi-truck, it’s important to check for any semi-truck electrical issues related to the ECU. When something is wrong, the ECU can cause damage to other electrical parts. Engine lags, misfires and stalls are all trouble signs that could be related to the ECU.
Trouble With Wires
As with any electrical-based system, wire trouble is another common place where issues can arise and need semi-truck electrical repairs. In a semi-truck, electrical problems can arise from the constant vibrations from being on the road. These vibrations cause wires to loosen or break.
When that happens, short-circuiting and, more seriously, fires. In addition, any loose wires can lead to issues with the onboard computer systems leading to engine troubles or transmission problems.
Damaged Battery Cables
Battery cables transfer the electrical currents from the battery to the semi-truck starter and other critical electrical components. Unfortunately, it’s not uncommon for semi-trucks to have battery cable issues.
Catching signs of connected truck electrical issues is vital as a damaged battery cable can cause several problems, from difficulty starting the engine to stalls and electrical shorts. Some common signs of damaged battery cables are the interior lighting dims, the engine failing to start, or you notice the loss of electricity.
Silent Horns and Sirens
Semi-truck horns and siren systems are crucial to a semi-truck safety system. Horns allow other drivers to know when your semi-truck is approaching. On the highway, a siren is much louder and more easily heard from long distances.
If the horn doesn’t work, you must replace it. If the siren stops working, then it likely needs to be re-wired by professional semi-truck electrical repairs. Never do the work on these issues alone; a professional mechanic is the best person for the job.
