Questions answered in these manuals
How do I adjust the generator output voltage?
Adjust the volt VR on the AVR board or use an external 1K ohm trimmer. Turn the trimmer clockwise until the rated voltage is reached.

What should I do if the generator fails to build voltage?
Check for reversed field polarity or insufficient residual voltage. If polarity is reversed, swap F+ and F-. If residual voltage is below 5 Vac, flash the field for 3 seconds using a 3–5 ohm resistor for full wave or 5–10 ohm for half wave AVR.
