Well it has drive to the spindle motor by the sounds of it. Whether the head
assembly is intact is another matter.
I think you can swap the boards on these things and expect them to still work -
so using the combination of your chassis / motor / platter assembly and the
logic board off a good drive might be enough - unless it is a fault in the head
assembly.
I have a Prodrive LPS 540AT in front of me right now which is likely the same
thing as a Lightning. There seems to be just the one ribbon cable connecting
the logic board to everything so a swap wouldn't be tricky and might cure
things. Those drives used to be everywhere at one point so finding one
shouldn't be too hard.
Do double-check your drive cabling and BIOS settings (assuming it's a PC you're
hooking up to) etc. - modern PC's seem to have a few billion settings for the
disks and probably think you're using a new drive; they may make incorrect
assumptions about data rates etc.

I know Western Digital used to release diagnostic utilities for their drives
and held them on their website; there may be similar Quantum ones floating
around.
