But like you, I wouldn't mind some confirmation on this....?
I'm watching this thread with interest as I'm not 100% confident that my sh775 will work with single phase. I've 90% completed the rewire so I will find out soon enough!
As long as the regulator is designed to treat each phase independently you can get away with using a 3-phase reg/rec with a 1-phase system. It does put more stress on the reg/rec since two circuits would then have to do the work of three. But in the world of factory reg/recs from the last 35 years or so, they seem to handle it fine.
(Older reg/recs used a design where each shunt triggered the next shunt, so you had to have the correct order of phase wires. Notice the oldest of the Kz's have stator wires that are color coded for proper sequence. They kept this color sequence for a few years even after they transitioned to non-sequenced regulators, so the sequence doesn't actually matter on most Kz's. If you were to use one of these sequenced regulators with single phase, you might get poor regulation. Chances are, you couldn't find one of these in service anyway.)
Whenever you rewire, it wouldn't hurt to run one extra phase wire from the stator housing to the reg/rec area. Then you won't have to open the loom if you find you need 3-phase.
