Don't think this is it. It doesn't smoke until I remove the hot wire from
the gauge. It doesn't appear to have melted the insulation off.

Sounds like you're grounding the power lead, and you've probably melted the
insulation off of one of your wires (the smoke).
I had a SUNPRO gauge that did that in my '50 Ford Truck...But I seem to
remember it was for the fuel gauge. The gauge should have two nuts on each
post. But I didn't have enough nuts, so I loosened the one that held the
meter assembly within the gauge casing, so the fork connector was affixed.
Well, the assembly IS NOT supposed to touch the casing, and if you've had
movement on the mechanism (Such as by loosening the nuts that hold the
assembly in place) and it's touching the casing, then your hot wire lead
will, for all intensive purposes, be going directly to ground. And the thin
wire can't handle the load, heats up and melts the insulation.
But this is only one hypothesis.
