I have been having a lot of problems getting a Fcub to charge,a 6 volt system. I replaced the regulator because the fine wire was broken in it. I have looked at quite a few post about repolarization of the generator and all say to short battery terminal to arm or gen terminal. Well on my regulator I have terminals labeled L, Bat and Field. Does this mean I should short the bat and field terminals in this case? What does the L stand for.

Under the Regulator there must be a ARM (or GEN) terminal hiding. It just must be there.
The L terminal is hooked to the fuse for the lights, and also supplies ignition voltage if it is a coil and points ignition, if a mag, no voltage goes to it ever.
The Bat terminal hooks to the Amp gauge, on the terminal not connected to the big terminal on the starter switch. That Load terminal should not have a supply going to the lights with this regulator, Now supplied by the L terminal wire.
All wires mentioned should be 10 gauge. The F terminal should never be touched with the Bat voltage, it will burn out the regulator. Jim

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.
