terminal 61 on outside of gen puts out 5 1/2 to 7 1/2 volts pending RPM
terminal 51 puts out 5 1/2v regardless of rpm
seems like whoever rebuilt the gen flipped the two wires inside?

my guess is battery wired to terminal 51 is draining battery and not charging.
anyone?

I think the same principles

I think the same principles outlined here apply - google Understanding And Maintaining The BMW /2 Electrical System and go to page 14. Should give you hints.
