Dead Servo?

Posts: 1
I'm having a problem with a Parallax mini servo with a BS1 dx. When I connect a standard servo, it works fine. But the mini just quietly whines or may unresponsively go clockwise. Also, when the mini is attached, the stamp won't download.
Real simple software commands just moving it from position to position.
' {$STAMP BS1}
SYMBOL temp = W0
start:
DEBUG "back"
FOR temp = 250 TO 70
PULSOUT 7,temp
PAUSE 50
NEXT
DEBUG "forward"
FOR temp = 70 TO 250 STEP - 1
PULSOUT 7,temp
PAUSE 50
NEXT
GOTO start
I'm thinking the servo is bad but not sure how to test it other than swap it out with a good one. I'm a hardware novice. I bought it new a couple of months ago but this is the first time I've tried to use it.
Any Suggestions?

·· If you're sure of the wiring on it, it could be bad.· It sounds like the servo is drawing the supply down.
