I havn't worked with the exact motor you have, but I've tinkered with a
similar one. Hope this helps.
These guys look like a (from a circuit-sense) as :
AC line -----------*------ switch --| |-----
| |
Stator Start
Coil Coil
| |
| |
AC line -----------*-------------------------
The switch is closed when the RPM is low (~75% rated speed). The direction of
rotation is determined at power-on. If you disconnect the starter winding, you
can manually start a motor in either direction. Better yet, just switch the
'polarity' of the stator winding with respect to the start winding to reverse
the direction.
To get your motor to run:
Connect terminal 2 to AC line.
Connect terminal V to terminal 1
Connect terminal 4 to AC neutral
Connect terminal 1 to AC neutral
To reverse direction, interchange 1 and 3.
