NOPE DO NOT SHORT BAT TO FIELD
Frank, some tractors used a 3 terminal (BAT ARM FIELD) Voltage Regulator while others used a 4 terminal (BAT FIELD LOAD ARM)
On many 4 terminal VR's the ARM is off on one side all by itself or underneath and it may be hard to Poalrize by momentarily flash jumping from BAT to the ARM (underneath) terminal. In that case I tell folks to jump from BAT direct down the the gennys ARM post to Polarize.
If a 3 terminal VR (no LOAD terminal) or a Cutout Relay system, loads were often fed off the load side of the ammeter (if it had an ammeter). If a 4 terminal VR, loads were fed instead off the VR's LOAD terminal.
