Default futaba 9252

Ok I admit I pluged it in wrong and when I did a flight control check the left aileron servo locked full up. when I pluged it in the correct way it still wouldnt work so whats going on, the servo not that old and didnt think it would hurt any thing obviously it did and suggestions on why it doesnt work now.

Might as well send it in for repair. The 9252 specifically and some(all?) other Futaba digital servos cannot be plugged in backwards without blowing the input circuit. Usually happens when you use multiple universal extensions on ailerons. If you use Futaba J extensions it cannot happen. Otherwise use acrylic paint to put colored dots on the correct side of the male/female connectors you commonly plug and unplug each flying session. The colored dots have the dual purpose of identifying the correct mating connectors and the polarity.
Don't ask why I had to figure this out.

I don't understand how you plugged it in wrong then. Are you using a receiver that you can plug a servo connector into either way around?
