Hi OSM, finally found the wiring diagram and scanned it, sorry about the coffee stains. The drawing you need to follow is number four, just leave out the diode, resistor, switch and battery which can be used to flash the field winding.

Thanks to everyone for the finding and scanning and posting. That gets me on the right track.
What im having trouble with is the settings on the AVR.

There are three pots labeled VOLTS STAB and U/F and a Red Led.

Volts:  I'm guessing that with the prime power running at temperature and the generator running at 1500 rpm i set this to give me 240 volts. (Volts makes seance)

Stab:  Guessing that i load the generator up and and adjust this till i have no drop in output voltage as i  increase load? (Stability off the output is what i guess this sets)

U/F: To set the uf knee point This pot is covered so I'm guessing its already set to were its supposed to be?

And what the led is for and what settings it relates to i have know idea.

The saga continues. ;D

I think for fine tuning, you start with the RPM close to 1500, and adjust it till your frequency is correct at about 20% load.  ( 60 hz or 50 hz ) Then at that frequency, you adjust the voltage to where you need it to be.  I see about a 4 hz swing in Fq from no load to full load in my system.
