    Tips: What is the difference between a starter relay and a starter solenoid?

    A starter relay and a starter solenoid are components used in the starting system of an internal combustion engine, but they have distinct roles and functions:

    1. Starter Relay:
      • Function: Acts as an intermediary between the ignition switch and the starter solenoid. It uses a small current from the ignition switch to control a larger current to the starter solenoid.
      • Location: Typically located in the engine compartment, often mounted on the fender or firewall.
      • Purpose: Ensures that the high current needed for the starter solenoid does not pass through the ignition switch, protecting it from potential damage.
    2. Starter Solenoid:
      • Function: Engages the starter motor to the engine's flywheel and allows a large current to flow to the starter motor.
      • Location: Usually mounted directly on the starter motor.
      • Purpose: Pushes the starter gear to mesh with the flywheel and closes the circuit that powers the starter motor.

    In summary, the starter relay controls the activation of the starter solenoid, which in turn engages the starter motor to start the engine.
