🔌 Function

The voltage regulator controls charging voltage from the stator to prevent battery overcharge and support stable electrical-system operation.

⚠️ Common Signs of Failure

  • Battery not charging
  • Battery overcharging
  • Dim or erratic electrical output
  • Melted regulator wiring
  • Charging voltage outside specification
  • Tachometer issues on systems using charging signal
  • Regulator runs excessively hot
  • Charging output returns when a known-good regulator is fitted
