What voltage goes to the crystal? I may have had my scope scale too high and
just didn't notice, but at first glance I don't think it was getting power.

Yes, the black wires are the thermistor.

The crystal has three wires.  Two are actually connected
to the crystal electrodes.  The third is the case.  The
case is fastened to the casting with a screw.  The only
way the casting gets an electrical ground is by way of the
crystal ground screw and ground wire to the board.
The wires are welded to the crystal, so if you want to
disconnect one of them, you have to unsolder it from the
PC board.
