Hello!
I’ve a new 325 Hitec standard servo but it doesn’t works and after a few seconds it become very hot!!!
When I connect it in a BBII or SSC-32 all servos pre cablated stop to work!!!
Suggestions?! 
Sounds like to me, that either the servo is fried and/or whatever the servo is installed in is seized up… Check to make sure that the servo can move.

What do you mean with “the servo is installed in is seized up”?
No the “hot servo” can’t move!!!
He means to ask, if you remove the servo from the arm, can you physically move the servo horn?
Yes with my hands I can move the servo but I try to connect it on SSC32 but it doesn’t move
Servo is fried then.
If the servo doesn’t move when theres no load, but still connected right, then it’s probably fried.
Place the servo, in the same slot as another working servo. If it still doesn’t work, it’s fried.
I had a similar dead servo before, the control board inside the servo was fried. (it came that way, i bought a bulk set of servos off ebay, got a bunch of servos for dirt cheap. but a couple were dead) Still, 8 out of 12 servos working, for the price of 1 new one.
You can try opening the servo from the bottom and see if it’s anything that can be repaired.
Maybe a solder ball or something short circuiting inside.
It takes 5 minutes to check it out, never know if the servo can be saved.
If the board is fried, don’t throw out the servo, just label it dead and put it away, you might need the gears or casings to repair another servo later on.
Yes,
I’ve placed the servo in the same slot as another working servo but it still doesn’t work!!
I’ve also opened the servos but apparently all part are right! How can I know if there is a short circuit?
I don’t think that the board is fried because the ather servos workking well…
The fried board i was talking about, was the circuit board inside the servo, not your SSC-32.
Your servo definitely sounds dead to me, sorry. Just keep it for parts, and buy a replacement.
Ok!!! I’m scared!!! 
In your opion it’s possible use the motor inside the servo? It works!
Many thanks Fallentine!!!
Keep the motor as spare parts.
Often times you can turn 2 broken servos into 1 working servo.
1st servo, bad motor
2nd servo bad controller board
3rd servo bad gears
take the motor from the second servo, put it in servo 1, take the gears from the second servo and fix servo 3.
And you’ll still have the case should case/shell ever crack on another servo.
Dont forget the wires, can replace a bad wire, or even make an extender.
When you try to salvage as much as i do, nothing goes to waste.
Edit: i just now noticed in your original post, you said it was NEW.
If that’s the case, send it back for a replacement.
Good idea!!!
Yes, I will try to contact my seller because the servo are new!
