wire x-x, y-y, 1-1, 2-2, 3-3.  apply power to x and y terminals.  its a
good idea to check that the case isn't shorted to any of the windings. 
after exposure to moisture the windings tend to develop high impedance
leaks to the case which can make for nasty shocks if you forget to
unplug them before going up the tower.



To sort out a prop pitch and synchro combination:

well... if its normal you should see: 

2 fat wires... these are power to the motor. apply power and see which way it rotates, reverse if needed. 

5 other wires for each synchro. check continuity from each wire to every other wire. you should find 2 of them have continuity to each other and not the other 3. the other 3 should have continuity to each other. apply excitiation voltage to the 2 wire group. connect the other 3 in any combination. rotate the antenna, if the synchro turns the wrong way reverse any 2 of the 3 wires. if the indicator is 120 degrees out rotate all 3 wires one terminal and try again.
