A starter relay is an electrical device that completes a high-current circuit to engage a starter motor. Starter relays are found in vehicles with internal combustion engines, and they are essential for starting the engine. When the ignition key is turned to the “start” position, the starter relay sends a signal to the starter motor, which then engages the engine’s flywheel and starts the engine.
Starter relays can fail over time, and when they do, they can prevent the engine from starting. There are several ways to test a starter relay to determine if it is faulty. One way is to use a multimeter to check for continuity between the relay’s terminals. Another way is to use a jumper wire to bypass the relay and see if the starter motor engages.
