Installation Guide
- Disconnect the battery negative terminal and ensure the ignition is off to prevent electrical shock.

- Disconnect all electrical connectors from the old regulator, noting their positions or taking a photo for reference.
- Remove the mounting bolts securing the old unit to the engine bracket.
- Clean the mounting surface to ensure good electrical grounding and heat dissipation.
- Position the new rectifier/regulator in place and secure it with the original mounting bolts, tightening evenly.
- Reconnect all electrical connectors to the corresponding terminals, ensuring each connector clicks or seats fully.
- Verify that all connections are clean, tight, and free from corrosion.
- Reconnect the battery negative terminal.
- Start the engine and check for proper charging voltage at idle and higher RPM using a multimeter (typically 13.5–14.5V).
- Inspect for any unusual heat buildup or loose connections after the initial test run.
- Reinstall the cowling and secure all fasteners before returning to normal operation.
