Grey and Davis wiring

Post by Charliechalmers13 » Wed Feb 25, 2015 7:25 pm

So far so good with the '13 Chalmers. Now I'm seeking any help via diagrams, sketches or schematics on the wiring of a Grey and Davis type 'G' generator and a Grey and Davis type 'B' switch. The generator has 3 wires out, a red, black, and a white. Any thoughts??

This comes from 1919 Dykes manual. Not much info, apparently the friction clutch in the generator maintains it at a constant speed so that output is the same at various engine speeds. Also it used electromagnets instead of permanent magnets. It also needed a cutout circuit to disconnect it from the battery when the car was not running. All in all very complex and no doubt hard to keep operating.

I would be tempted to "hide" a Volkswagen 6V generator inside the case and then wire it per the diagram below.

Do you want a real tomahawk or a rubber tomahawk?
