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...?

I believe that the 10dn Delco alternator can be bumped up to a 55 Amp by just using the heavier windings. Seems like I put some 72 Amp windings in a 200 once for cab,AC, and planter blower fan load. I would suspect a bad diode is causing the field terminal condition. There's not much to those alternators, stator, windings, brush set, and two sets of diodes.

Contacts are probably sticking on the voltage regulator

Bad voltage regulator was what got me all excited yesterday, l didn't have new one but had a newer style alternator with the internal regulator on the shop shelf that I had rigged up as a spare for one of the 8010's if needed in a pinch, jumped the field wire to the ignition switch and all is good, tack don't work very good but I can live with that for a while. Thanks Dave
