Thanks John, I will check the motor drive IC as you suggested. I know the
motor works, subbed my own drive just to see of it turns. I did notice when
I first plugged it in that the heads would rock but not spin. I know other
units will spin momentarly at pluggin. Now I don't notice the head move at
all. The led for the end sensors work and the sensors trigger normaly. I am
at a loss.
Will let you know about the motor drive IC later
