How Corroded Ground Straps Disrupt Your Vehicle’s Electrical

In a vehicle, the electrical current doesn"t just flow out from the battery; it must flow back to the battery to complete the circuit. This return path is provided by "ground straps"—heavy-duty, often braided metal cables that connect the engine block and transmission directly to the car’s metal chassis. Because these cables are exposed to the elements and engine heat, they are highly susceptible to corrosion, which acts as a hidden barrier to your entire electrical system.
