🔌 Function

The rectifier / regulator converts AC current from the stator into regulated DC voltage for battery charging and engine electrical-system operation.

Common signs of failure:

• Battery not charging

• Overcharging or high battery voltage

• Tachometer not working or erratic

• Burnt or melted regulator wiring

• Blown charging-system fuse

• Battery goes flat while running

• Charging voltage remains incorrect after stator and battery checks

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
