I dont know how to get at it BUTTTTTTTT Its the Generator NOT the Voltage Regulator that gets Polarized BEFORE you start the tractor, otherwise (if gennys is at opposite polarity) you might damage that new Voltage Regulator...... Polarize the genny n then try it MAKE SURE that BOTH the genny and the VR have good grounds!!!!!
TO POLARIZE A GENNY IF YOU CANT GET TO THE VOLTAGE REGULATOR
Use a lil jumper wire to momentarily flash jump/spark any hot ungrounded battery voltage feed source (like from hot ungrounded battery post or where the big battery cable attaches to a starter switch or solenoid etc) to the gennys ARM post and you should get a spark... NOW ITS POALRIZED
I will post a link to my Non Charging Troubleshooting Procedure, but heres a short clip from it which may provide insight unti you do all the tests in my procedure. POLARIZE THE GENNY FIRST BEFORE STARTING IT REMEMEBR.... Also if you reverse a tractors polarity that uses an ammeter its leads need swapped so it dont register backwards...Also put a voltmeter on the batery and setting it ought to read around 12.6 volts but then once rinning at fast RPM it should rise to the 13 to 14 and over range IFFFFFFF shes charging...
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
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.
If polarizing and a good ground on the Genny and VR dont help, go here and these simple tests can help diagnose the problem......

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
