Wellllllll if you let the smoke out of it theres a good chance YES, maybe the Fields burned open or shorted out!!!!!!!!!!!
Heres how to determine if the Gennys is good:
TO DETERMINE IF ITS A GEN OR VR OR CUTOUT RELAY PROBLEM
5. a) VOLTAGE REGULATOR SYSTEM: With the tractor running, temporarily ground the Gens Field post to case. If she charges then but NOT otherwise, the VR may be bad, or a wires missing from VR's Field post to the Field terminal on the VR, or the VR isn�t well grounded.
b) IF IT�S A CUTOUT RELAY SYSTEM and she charges only if you dead ground the Field but NOT otherwise, its either a bad switch or the switch isn�t well grounded or else the wires bad or open from the Gens Field post up to the switch. INSURE THAT GOOD SWITCH GROUND AND WIRING
6. If she still don�t charge, leave the Field grounded and jump a wire across from the VR or Cutout Relays BAT terminal over to its GEN terminal (jump by passes the cutout relay) and see if she charges. If then but not otherwise, a VR's cutout relay isn�t working correct (maybe points burned/carboned) or a Cutout Relays NOT working or not wired correct.
7. With the 2 steps above, you have basically by passed the VR or Cutout relays functions, so if she still don�t charge, you're left with a bad battery or wiring or the Gen itself.
8. MOTOR TEST. You can Motor test the Gen. If its grounded and you remove the belt and apply hot battery voltage direct to its ARM Post and have the Field Post dead grounded to frame, it should motor n run well (Armature n Brushes and Commutator likely okay). Then, if you next remove the Fields ground and it speeds up some, the Fields probably good. If it passes both those tests, it should charge, and if not, it may be a wiring or battery or grounding problem. The hot battery voltage may be taken off the VR's BAT terminal or the starter post or the battery itself for this test.

Today's Featured Article - Gettin My Old Tractor Home - by Clayton Sweeney. My name is Clayton Sweeney. I am from Southern Maryland in a small town called Lothian. I am 20 and my father and I are the proud owner of a 1954 Allis Chalmers WD-45. When I was 18, I dated a girl in the next county over. Her family are tobacco farmers. It was a cold Thanksgiving evening, and we were going up to her Grandparents house. As we passed one of their barns, I noticed something orange in the corner of my eye in this old shed. It was pretty dark and I asked what it was
