One way to identify which terminals are which on a Class A 3 terminal (BAT ARM FLD) Voltage Regulator I have successfully used is as follows (may or may not work on allllllllllll VR's, be warned):
I used an ohm meter on a relatively low ohms scale say 100 and attach one lead to the case/frame/ground metal and probe with the other end.
BAT should have near infinity ohms like an open circuit it is under those condition....... FLD would be very low ohms maybe less then 10 down to near zero, depends on the particular VR.... ARM may be in the range of say 20 to 50 or so ohms as that's the shunt winding portion of the cutout relay.
NOTE this is NOT intended as exact, only ohms ranges with BAT highest, FLD lowest, ARM mid range and again, it MAY NOT WORK OR BE TRUE FOR ALL VR'S so don't anyone have a calf, I'm ONLY saying its worked for me.

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
