2 prong Voltage Regulator Part Number

Well-known Member
Guys, I have a 1952 Allis Chalmers CA with the original 6 volt system. It has what I think is a voltage regulator that has 2 electrical prongs. It is mounted on the generator. I need to get a new one TOMORROW so I can get the tractor back together. Would anyone know where I can get one? If so, the part number.....a napa or o'Reilly part number would be great as that is where I will go.
 
A two prong should be a "cut out" not a voltage regulator, every regulator I have seen is 3 or 4 prongs

this site also sells the cut out in their parts section - Voltage Cutout 6 Volt Part Number 574459

$28.37

The one that's on the tractor looks original. The prongs are side by side, not on opposite ends like the one you pictured
 
If there's only 2 terminals, Bat and GEN/ARM its a Cutout Relay instead of a full fledged 3 or 4 terminal Voltage Regulator. Be sure and get one for 6 volts and suitable for your ground (Pos or Neg). If you cant get one you could get by with a 30 amp Diode instead available at electronics suppliers, wire at the correct Polarity, one lead to Battery/Ammeter wire, the other to the Gennys ARM post.
