Trying to hook up older 6 volt generator. There is NO marking as to field and armarture post. As far as I can deduce the smaller diamater post out of the generator is the field. The larger one being the armature. Is this correct????? I do belive the voltage regulator is 6 volt, how can I be sure???? The tractor (cockshutt 30) is postive ground 6 volt. AS I understand the generator can be polizerized either postive ground or neg ground, is this correct??? What about the regulator being polizered postive ground??? Exactly how doe I polizer both generator and regulator??? JOHN T you escaped to the sunny south before I was able to cominder your services to guide my efforts on my Honda ES 4500. as to battery discharge.

Delco generator? If so the field gets "grounded" or eventually connected to chassis to excite the field coils and increase output.
Which polarity do you want? - or + chassis? The ignition coil will throw a superior spark if matched.
Field is the smaller wiring.

Yes I want Postive ground Thanks

Generators can do eiither, but regulators ar set up for one or the other, I beliieve.

Gee Neighbor, you knew I was leavin lol


As far as I can deduce the smaller diamater post out of the generator is the field. The larger one being the armature. Is this correct?????

YES thats what Id expext as the ARM carries more current then the FLD. If all is there n wired right with an ohmeter to case frame the ARM is less resistance to case frame then the FLD.

I do belive the voltage regulator is 6 volt, how can I be sure????

If theres no label you would have to bench test it and apply DC voltage across the GEN/ARM post and case frame and see if the cutout latches in at like 6 to 7 volts versus 12 to 14.


The tractor (cockshutt 30) is postive ground 6 volt. AS I understand the generator can be polizerized either postive ground or neg ground, is this correct???

YES the genny will work at either Polarity just polarize it before start up as it can harm a VR otherwise

about the regulator being polizered postive ground??? Exactly how doe I polizer both generator and regulator???

Its ONLY the Genny that gets polarized. Some VR's will work at either polarity while others may not.

Hook it up at the ground you want,,,,,Poalrize the genny,,,,,start her up n see what happens

Battery + to chassis. Wire from distributer goes to coil's +.
Personally I loosen the fan belt and push the cutout together or jumper it with a screw driver. The generator should spin as a motor and polarize it's self. Also proves the generator's brushes and armature are functional.
