Starter Relays

A starter relay is an electrical component in a vehicle's starting system that helps control the high current needed to start the engine. When the ignition key is turned to the start position, a small current flows from the battery to the starter relay, this activates the starter solenoid relay, which closes its internal contacts to allow a larger current to flow directly from the battery to the starter motor. The starter motor then engages and turns the engine over, initiating the combustion process. The starter relay acts as a switch to manage the high current safely, preventing the ignition switch from handling the high current directly, which could cause damage or excessive wear. It also ensures the starter motor receives sufficient power to function properly, contributing to reliable engine starting.
