Tom, that MT uses a headlight switch controlled generator field so the easiest way to polarize it is to ground the generator [F] post {smaller of the two} to the generator housing [you need a good clean ground], then monetarily jump battery power from the starter's big battery cable stud to the generator's [A] post {larger of the two}. You should get a spark & that tells you it is polarized. ~On your charging issue...If the polarization doesn't get it charging make sure the ammeter is wired correctly. There should ONLY be one wire hooked to the battery side post of the ammeter & ALL OTHER LOADS including the battery wire from the cut-out relay should be hooked to the other post of the ammeter. If it shows a reverse reading when done just reverse the wires from side to side.. ~If it still doesn�t charge, start at the ammeter side of the cut-out relay & MAKE SURE you have battery power to that terminal [if you don�t find out why]. If you have battery power there then start the tractor & run at fast idle. Then ground the [F] post on the generator [does it charge now?]..If so, you have a failed ground at the headlight switch, or a bad headlight switch, or an open in the wire from the generator [F] post to the headlight switch, or a bad generator. ~If still no charge, leave the [F] post grounded & then jump the [A] post on the generator to the ammeter side of the cut-out relay, [does it charge now?]..If so you have a bad cut-out relay, or an open in the wire from the generator [A] post to the cut-out relay, or a failed generator. ~If all the above doesn't find the problem MAKE SURE the generator & cut-out relay have a good CLEAN ground. ~If it still doesn�t charge you probably have a failed generator, or possibly a stuck brush or improperly adjusted 3rd brush�
