Hopefully you just have the wires in the wrong  place.
Take an ohmmeter, and on the lowest scale, measure each wire with  respect to 
the others. If the antenna is not against a stop, the two wires  that read 
about 15 ohms are the motor wires (wires 4 & 5). If the antenna is  against the 
stop, you will be measuring the motor through a diode, so in one  direction 
you will read near infinity, and in the other direction, you will read  about 
200 ohms.
The third wire should have no continuity with the other two unless  the rotor 
is against a stop. Then, it will be through a diode and a 2.2K  resistor - so 
it would read about 2.5K in one direction, near infinity with the  leads 
Hope this helps.
