the HOT WIRE to the battery is probably always hot.... You might have a small leak internal that goes to ground... that could keep the F terminal warm..

Disconnect the battery cable terminal should work...

you have an external voltage regulator... are you thinking the contact INSIDE the voltage regulator is STUCK closed and causing a draw when you connect the Field wire ?

Maybe the REGULATOR and not the Alternator ?

Could be a shorted diode in the alternator or contact in regulator welded to hot post. or connectors put on wrong terminals...
  55 amp alternator means that tractor has a different alternator put on. Original was 32 amp alternator.
 Is that 1100887 alternator still the old Delcotron style? no regulator inside it...?
