Artfull's diagram makes sense, I had to physically dig into the
windings to find that other connection (it was not brought
out to the connection board) on my H.F. drill press.
It was touch and go for awhile (I'm pretty shakey), but
got the wire stripped, and connected, and glued back down
into the rest of the end windings (for vibration protection).
I applied spray varnish liberally as well, those motors are
pretty shaky in that respect (dry windings)
