Check the fuses on both the battery line and the AVR board itself. A blown fuse is a common cause of "no voltage" issues.

These wires connect to the exciter stator. an-5-203 avr wiring diagram pdf

Use a torque screwdriver to ensure all connections are tight. Vibration from the generator can loosen spade terminals over time. Check the fuses on both the battery line

Before beginning the wiring process, verify that your unit matches these standard operating parameters: Specification Main Winding Input 400VAC, 50Hz/60Hz Auxiliary Winding Input 55V – 220V AC Maximum Output 120V / 5A DC (for 10 seconds) Voltage Regulation < ±0.5% (Steady State) Field Resistance Min. Residual Voltage > 5V / 30Hz 2. Wiring Diagram & Terminal Connections Use a torque screwdriver to ensure all connections are tight

If using an external voltage control, connect a potentiometer. This allows for a ±12% fine-tune adjustment.

Ensure polarity is correct for the DC output.
