Passed the DS test today~

[Ben Dover]

Thats the Dumb Sh1t test, for those of you that don't know.

I spent the better part of the last two evenings cleaning up the light sockets and the circuit board on my ’82 C30 instrument panel.
Couldn’t seem to get much light from the bulb in the upper right corner, so I pulled it (and it’s attached wire) to take a look-see. The wire seemed to be a ground wire attached to the top of the ashtray mount, so I took it in the shop for a little testing.

Absolutely NO continuity from one end of the wire to the other. Figured it was shorted, so I clipped one end off while leaving enough for a crimp connector. Nuthin’. Clipped off the other end in the same way. Nuthin’. Checked the middle piece which was left after clipping off the ends. Nuthin'.

Stripped off the end of the middle wire to see what kind of wire it is.

It’s Fibre Optic cable.

Who would have thought GM used optics to light its ashtrays in ’82.
