Semi trucks have a number of different electrical components and systems, which means more opportunities for failures. Truck electrical problems can happen in one of the multiple electrical components. There is the starting system, charging system, and lighting. Electrical problems in semi trucks are typically a result of an interrupted circuit which causes increased electrical loads on heating and A/C systems, lights and engine parts.
The batteries in your rig have the important job of supplying power to the starting system as well as powering all of the accessory electrical components. When one of these battery-dependent parts malfunction, it could cause something simple like a cab light outage all the way to a electrical system failure. It’s crucial that you maintain your battery’s health to keep your fleet running efficiently.
A semi truck electrical system consists of the battery, the alternator, and the starter. As simple as it seems, these three basic parts are responsible for starting your engine, keeping it running, and supplying power to all the lights and systems in your semi truck.
