🔌 Function

The starter relay / solenoid uses a low-current control signal to switch high-current battery power to the starter motor or relay circuit.

⚠️ Common Signs of Failure

  • Starter does not crank
  • Solenoid clicks but starter does not turn
  • Intermittent cranking
  • Starter remains engaged
  • Burnt or corroded solenoid terminals
  • Voltage reaches input but not output
  • Circuit works when a known-good solenoid is fitted
