Running a wire from #2 terminal to the main alternator output post does not make it a "one wire" alternator. It would be a "two wire" setup that won't work. I'm calling it "two wire" since you've got two wires added.
To convert to a "one wire" you need a $10 self- excite regulator. Once installed - just one wire is hooked to the alternator at the output post.
With a non-self-excite regulator on a Delco 10SI, 12SI or 18SI, you hook #2 to the output post - like you already did. Then hook a third wire to #1 that provides initial "excite" current from a switched power source. If running from an IGN terminal on a key switch - a 5 amp diode should be hooked in series so you can shut the tractor off. If using a ACC terminal -no diode needed.
If it's charging - you read 14 volts or more. Alternator also has a "full charge" regulator bypass in the back. Just stick a small screwdriver or nail in the back to make it get "full field" and charge.
