[TriEmbed] Servo will not stop spinning

[Craig Cook]

I purchased a Futaba 3003 from ebay ~$4.  It keeps spinning when I initialize it. Should I call it bad and get another? (I have a micro servo working fine).

I pulled the top cover off. Apply power, nothing happens.  I add the signal from my arduino and it starts spinning.
Using this code, it should do nothing.
#include <Servo.h>

const byte servoPin = 5;
const int STOPPED = 1500;
 
Servo servo;
               
void setup()
{
  servo.attach(servoPin);
  servo.writeMicroseconds(STOPPED);
}
 
void loop()
{
 
 
}

With everything assembled if I force the blades to the left until I get resistance, turn the signal and power on, it rotates to the right. Stops and keeps shuddering.

With these symptoms, could it have been something I did to break it? Too many volts? 

Thanks
Craig
