Ouch!  Dosen't sound good .... but it may be the multipak that's hosed, not the
controller. Have you considered plugging the controller into the CoCo3 to see
if it works? (If this is a real old controller, don't bother. It will need the
MPI for the 12 volts it requires. But if it's  one of the newer, smaller
controllers that only 5 volts, you should be in good shape.

Do the drive lights light up immediately upon power up? If so, is it possible
you've somehow flipped the cable around? This is indicative of having the cable
switched.
