Fortunately, everything here is win/win, thanks to the 4400, which is definitely 6 volt.
I got the 6 Volt alternator today, and was thrilled, until I read your message. The voltage regulator has three terminals and says something like 'Echelin 110' on the cover.
I also realized that the 4400 has had a six volt generator hiding in it for the last few months, and there is a place in town that advertises that they can re-build it.
It kind of looks like one will end up as a six volt system, and the other . . . 12.
