One-Wire Generator

   No, that is not a typo, this gadget truly is a one-wire generator.

I have several old generators (thanks ORBill) that I am finally getting around to testing. This unit is a third-brush type and has no provisions whatsoever for controlling the field current; a quick google search for the part number 943U shows that it is for a 1931-34 Studebaker. Some further searching led me to a Studebaker forum where I found schematics that clearly show this generator having only one wire leading from the armature to the cutout relay.

The amazing thing is that it actually works! I realize that I am probably the last person on earth to learn that this was at one time state of the art technology, but I have always been a bit slow on the uptake 

8 Volts at ~8 amps
