One diode was smashed.
It was on of those little clear (glass?) diodes.
Are those called zeeners or something that
starts with "z"? Anyway, I didn't have a
replacement, so I just removed the leads and
left it at that. Later I decided to go ahead and
try the drive, and it worked. If somebody has
the schematics, the silkscreen next to where
the diode was is "C1" (it is in one corner of the
board).
If it has a C1 next to it you can bet it is a capacitor.
You should have rows of them on the card.
Is it is the one by the resistor and transistor?
Or the one by the two 'normal' looking capacitors on the other side?
There are way too many of them to be zener diodes.
And you should be able to pick out the 1N914 diodes.
It must be a cap as it did not affect the drive that much.
