A starter relay is {an electrical} system that completes a high-current circuit to interact a starter motor. Starter relays are present in autos with inside combustion engines, and they’re important for beginning the engine. When the ignition key’s turned to the “begin” place, the starter relay sends a sign to the starter motor, which then engages the engine’s flywheel and begins the engine.
Starter relays can fail over time, and after they do, they’ll forestall the engine from beginning. There are a number of methods to check a starter relay to find out whether it is defective. A method is to make use of a multimeter to examine for continuity between the relay’s terminals. One other manner is to make use of a jumper wire to bypass the relay and see if the starter motor engages.
