If it's still all connected it should be fairly easy to figure out the wiring diargam.

Hi Blue Cat.
If only it was that easy , I have tried always with out success !.
But today before putting in the scrap area. In a last minute reprisal I have stripped the generator only to find the field coil in series and the shunt field i parallel at the armature these i believe should be field in series.shunt in series connected together at the armature brush .The generator looks to have been rewired and connected wrong as the connection would be made at that time.Keeping my fingers crossed this is the problem, no wonder it was for spares when i got it about 6 years ago.

John.
