What Does This Starter Relay Do?

An electromagnetic relay switch in the starting circuit that carries the high current from the battery to the starter motor when the ignition key is turned to start. Protects the ignition switch by handling the high-current path separately.

Possible Starter Relay Problem Symptoms

If your machine is showing any of the following, a faulty starter relay may be the cause:

  • Single click when turning the key but engine does not crank
  • Starter motor not responding despite a fully charged battery
  • Relay chattering or clicking rapidly rather than holding
  • Intermittent starting failure that resolves by itself after a pause
