First, Let me admit I'm electrically challenged and the stroke nine months ago didn't help any. I have an International Cub Cadet that I bought cheap. It had been burned in a fire. I had to replace the the Electrical system from soup to nuts ( except the coil) The starter Generator is an Indian knockoff of a Delco CC rot. same for the regulator. Problem is that when I polarized the regulator I hit field first. Did I cook the reg.? I think now it's trickle charging, the battery goes dead after a few hours running. Yet it will continue running if the battery is disconnected. There is no ammeter on this machine. How do I hook one up? Did I ruin it? Will I have to scratch the price of a new regulator, Or can this one be saved? Thanks in advance, Rich

I have run tractors that had the regulator wired wrong; arm to field and field to arm. I have shorted the batt term to the wrong terminal trying to polarize. The ammeter didn't read a proper charge in any of those situations. Wired wrong the genny charged 25+amps all the time.
In each case when I corrected the problem and properly polarized the system gyrated for a second or two (watch the ammeter do nutty things) and then took off and charged just fine. That would be charge fairly strong for a few minutes after the start and then drop way back toward zero.
I gotta say, some of these threads on polarizing make my eyes roll back up in my head but my experience is that while getting it right can mean changing some wires around or making a mistep or two that when it's right it's obviously right and all in all it's hardly more complicated than falling out of bed.
My experience says if shorting batt to arm doesn't make it charge right then double-check the wiring., field to field and arm(gen) to arm and good ground. If that's right then shorting the batt to field to see if that works won't hurt anything. Could be wrong, don't think so. I know I've done it wrong, ran the tractor many hours over many months, and then corrected the problem and things worked fine. Moreover, I suspect if you short the batt terminal to another terminal on the regulator and you don't get a surprisingly big spark then it's the wrong term and you should short the batt to the other terminal to polarize. Shorting to the wrong terminal hardly shows a puny little yellow spark that is almost not there at all.

Rob.. though I'm glad you've been lucky in mis polarizing and connecting a regulator.. I'm not sure I would say that doing it wrong won't hurt things. I've attatched some 60's era vintage literature for the regulator on a piece of heavy equipment we have ( an ingram steel wheel roller.. with i believe, a delco genny ).. Bold lettering near the bottom says 'warning do not touch battery to field or regulator is ruined'.. etc.. or something to that effect.

And keep in mind what type of circuit your particular N genny is before polarizing it different ways.. the a and b circuits have different polarization and full fielding schemes.

you probably didn't hurt the VREG. Try it again, with the field terminal GROUNDED, then flash the Battery terminal to the armature terminal. Pull it off, and see if it will 'motor up' on your workbench with a 12V battery, and hope there's enough actual ferrous metal in your pole shoes to retain a residual magnetic field

Do you have a voltmeter? If so.. make a voltage check on the battery and then start it and see if the voltage comes up.

If you want to throw an ammeter in just to check genny total output, you can add it inline with the charge wire fron the regulator out to the battery. In that setup it will show you total output of the genny. You could also plumb it in similar to our N tractors, and show net charge/discharge from the battery. Ammeter would still be inline with the charge line from the regulator, except the location you draw power for the ignition would be on the incoming side of the ammeter... In that location, if the genny isn't charging.. the battery will be discharging, and the ammeter would refleft that.
