I'd say NO. The terminals may be there. They were on the internal 1-wire regulators I've bought. However, the jumper on some conversion diagrams was to the voltage sense #2 terminal. Voltage sense was intended to adjust alternator output to compensate for voltage drop. That voltage drop compensating feature has little value for a tractor with short wire runs and few accessories, and has nothing to do with exciting the alternator. If the #1 exciter terminal is going to be hooked up, you will need a wire from the switched side of the ignition switch. This is the same wire that is going to the coil. Since this wire goes to the coil, you will have to use a small dash "idiot" light or a diode to prevent the alternator from backfeeding the alternator. When that happens, the ignition key no longer stops the engine.
The early 1-wire regulators did have a low rpm problem, they had to be revved-up before the alternator would start charging. That problem was eventually fixed. When I bought a regulator to rebuild the alternator for my 2N, I made sure the regulator was the Low RPM version.
