🔌 Function

  

The regulator rectifier converts stator AC output into DC charging voltage and regulates the voltage supplied to the battery and electrical system.

  

Common signs of failure:

  

• Battery not charging

• Battery overcharging

• Tachometer signal loss on some systems

• Blown charging-system fuse

• Burnt or melted regulator wiring

• Voltage spikes at battery

• Electrical accessories behaving erratically

• Charging output returns when a known-good regulator is fitted

  

📦 Condition

  

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
