Common Symptoms of a Faulty Electrical System

A Dead or Malfunctioning Battery

Your truck’s battery can be considered the heart of the vehicle’s electrical system. Although a dead battery doesn’t seem like a big deal at first glance, aside from a minor annoyance, it can have several knock-on effects that can prove detrimental to the performance of your rig. The main issue is simply that, if your battery is dead, the truck simply won’t start. The battery provides critical electrical power to not just comfort devices like the cabin radio but to critical components such as your engine’s glow plugs, which are absolutely essential to the proper performance of your engine. A malfunctioning battery may not provide enough power to these core components and reduce the efficiency of your vehicle in the long run. This is especially important in cold weather, where your vehicle may have a harder time starting up, if at all, without the proper electrical flow. It’s ideal to replace the battery every two to three years to ensure the proper functioning of your electrical system. Additionally, if it’s possible, during the winter season bring your battery inside overnight or cover it up to reduce the strain on your glow plugs and other components.

Malfunctioning EGR Cooler

Standing for Exhaust Gas Recirculation, the EGR system is essential to filtering your exhaust gases and reducing the amount of NOx emitted by your engine. Virtually every modern rig possesses an EGR system, making it an essential component in your truck’s engine and electrical system. One of the components of the EGR system is the EGR cooler, which utilizes a sensor to deploy coolant automatically in order to lower the temperature of the cycled exhaust gases. However, as with any component that utilizes coolant, it’s possible for leakage to occur. A sure sign this has happened to your rig is if the exhaust comes out black or blue; if this is the case, then the cooler has sprung a leak and the coolant has ended up in the fuel. One of the main results of a malfunctioning cooler is that your engine will lose efficiency both in performance and in fuel consumption, as the engine’s combustion will be uneven thanks to the fact that it will need to consume more fuel than necessary to operate at normal levels. Thankfully, the fix is as simple as contacting the professionals so they can replace the faulty cooler according to the manufacturer's recommendations.
