Thanks Scott.
I have not tested it yet, but am now confident that it is a stationary field generator.
New to me, this is.
The coils on the stator cannot be anything but poles to cut the rotating armature fields.
I am a Marine Engineer by trade, so my experience is more towards the larger end of power generation. It did not initially occur to me that a stationary field was an option. I guess that the lower currents in a smaller machine allow it.
With the control drawing, switch the field and armature connections. When I drew it I did not even check, as I did not consider a stationary field.
The starter ( S ) is a florescent light starter, presumably to bring the contractor in a little earlier.
The scribble on the exciter line at the bottom of the drawing is a continuous line.
Note the 40 micro farad capacitor. This capacitor was strapped into the box and appears to be an add on. Perhaps added to the circuit when the VR transformer started to fail. I do not like it and cannot but think it would be responsible for some abnormal patterns in the output waveform, particularly as it is after the Bridge Rectifier.
The attached image show the clearly defined stator coils.
It also shows the slotted rotor, as opposed to wire wound coils of a more typical rotor.
Will rewire it and test later today. Southern Australia time.
cheers, Jack
