I an a mechanic, electrician and a fabricator of unusual vehicles. A friend brought a Lincoln SA-200 to me because it needed work. I need an actual wiring schematic for this unit. I was able to download a PDF file of the manual for this machine but there was no scematic in it. Someone has tried to work on this machine before and the wiring is a mess. Some of it is just hanging there with no indication of where it is supposed to be connected. I would appreciate any help with this problem. Thank you.
