Dreamcast won't turn on

The power light will flash but then go out and then when i try to turn it on again nothing happens. i have taken it apart and i have discovered that the motor that spins the disc seems to be a part of the problem. i got that information by taking it apart and then undoing things in the console and trying to turn it on. it will turn on just fine without this motor plugged in but as soon as i plug it in it kills the console. any ideas as to the actual problem? like a blown fuse or something of that nature? or is it that the motor is bad?
