I've aquired one of these recently. The motor runs fine. It's missing the gpo's, switches and everything else from the Carb side of the power outlet box on top of the alternator. I guess that stuff is for a 12VDC supply, and there's a connection problem for the 240V other side of the box because something critical is missing. Any advice on substituting what's missing will be gratefully recieved. The plastic root connector block is in situ, but has no outgoing plug. PS I do not know if this genset has brushes or requires a minimum load to produce its full output voltage. Pls advise.
