Sounds like this tractor does not spin the alternator as fast as the old one, so not enough rpm to self excite the thing. You should not have any problem just connecting it as a 3 wire unit, the last box of 1 wire regulators I bought had instructions inside that said if you needed a charge light or wanted it to excite at lower rpm, it's fine to wire it as a 3 wire alt , no problem. The size (amps) of the one wire alternator determine how much rpm it takes to excite the thing, a 37 amp alternator which is plenty for most classic tractor applications, will excite at half the rpm of a 61 or 72 amp model. You might also try a smaller pulley or swap out the larger alternator stator for the small 37 amp unit to get it to excite at lower rpm. Many of those tractors came with a 20 amp generator, so a 37 amp alternator is more than up to the job. At the typical auto parts store, you will find little to no difference in price between a 1 wire and 3 wire Delco SI alternator.
I like the 1 wire alternator for many old tractor applications, especially those with magneto ignition, you are replacing a 1 wire generator with a 1 wire alternator and don't need to clutter up the tractor with added wiring and switches.

Except for last fourth of July's Old Gold show in Springfield, Illinois, I don't remember when it was so hot. Nevertheless, the heat didn't keep vendors and visitors alike from enjoying the third annual Country Day's Event. Jane Elliott said the event was originally a one man show. "Barry Seiler, owner of Country Town Farm Supply store used to invite people up to the Johne Deere store. He would give hats and a free meal for everyone that brings a tractor."
