Your car's electrical system pretty much runs the vehicle. For instance, it allows you to turn the ignition, operate power windows, the stereo, AC, cameras and various sensors in a car. Therefore, it is safe to say that a malfunction in the electrical system can devastatingly impact a car operation. Thus, car owners must keep a close eye on their vehicle's electrical system to prevent components from becoming inoperable. Notably, knowing the various causes of auto electrical system issues is crucial for proper maintenance. This article discusses common causes of electrical problems.

Excessive Vibrations — When a car starts to vibrate, the problem will persist until you find a solution. In most cases, suspensions are to blame for excessive vibrations, affecting overall comfort. However, comfort is not the only thing you should worry about if your vehicle keeps shaking. The electrical system is also at risk if you consider the number of wires running underneath and around a car. Notably, wires and connectors inside a vehicle tend to move with the car's vibration, increasing the chances of disconnections and shut-off incidences. In severe cases, vibrations can cause metal or plastic parts to pinch an electrical cable, eventually cutting it into two pieces. Reducing or eliminating vibrations through suspension system repairs helps protect automotive electrical wires.

Extremely High Temperatures — High temperatures are nothing new in cars because the engine itself generates enough heat to burn your hands. However, most car parts, including electrical cables, are designed to withstand such high temperatures. Unfortunately, it does not mean that sustaining the high temperatures is safe for your car. For example, extremely high temperatures can melt the plastic insulation on auto electric wires, cutting off electricity supply to various components. Therefore, when you realise that the hood is getting hotter than normal, think about other systems such as electricals. Besides addressing the root issue, inspecting electrical wiring around the affected area is critical. It helps identify possible heat-related damages to wires for timely repairs.

Stuck Relay — Controlling the flow of electricity from a battery to various car parts is only possible with relay switches. The tiny components open and close circuits electronically and automatically to allow electricity to flow to various vehicle sections. However, relay switches can get stuck in the close or open positions, causing electrical malfunctions. For instance, when a relay switch gets stuck in the open position, it allows electricity to flow continuously even if the part is not in use. Thus, it unnecessarily loads a car battery, eventually draining it. Only a qualified mechanic can identify and release stuck relays.
