I have a model 1900 compact diesel (yr-1980), love this machine, have had virtually no problems with it, use it all over my woodlands. The ignition switch failed/jammed. I marked the wires & had the switch rekeyed, but upon reassembly discovered the marks had blurred & I don't want to put them in the wrong position/burn something up. Anybody out there have a diagram, a photo, or can direct me on which wires go where? It has 5 poles that are marked/numbered on back of the switch. If anyone can help my out, it would be greatly appreciated. Thanks
