🔌 Function

The rectifier converts stator AC output to DC voltage for battery charging and electrical supply on OMC charging systems that do not use a separate voltage regulator.

Common signs of failure:

• Battery does not charge

• Battery voltage rises too high

• Tachometer drops out or reads incorrectly

• Burnt rectifier leads or overheated case

• Blown charging fuse

• Repeated battery failure from overcharging

• Charging output fails stator-to-battery voltage test

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
