Does the glove box light require a ground wire on a 48 DeSoto?

Most components on my 48 DeSoto are grounded by the metal dash.  But my glove box light is screwed to the side of a cardboard glove box.  Would it need a ground wire?  I guess I could test it with a multi-tester.

I don't know how DeSoto accomplished it, but it has to ground somehow or it wont light.

No ground and the circuit is open. It needs a ground for sure.

You sure there's not a little metal bracket missing? That's how they were on some cars. Either way, shouldn't be hard to add a ground wire.

I would post this on the Mo Par page.

I found my old glove box light that was riveted to the old, long gone glove box.  You can clearly see the ground wire riveted to the old glove box light.  This is not shown in the car's wiring diagram.  I got another glove box light from a 47 DeSoto that was fastened to the cardboard with very small screws and nuts.  So I have to make another ground wire and mount it under the screw.  By the way, that tube thing is for the glove box light to do double duty as an ashtray light also.  Oddly, the 47 light has a plastic prism inside that tube, but the 48 tube does not.

Does the clock also need a ground wire?  Is that what this post is for on the clock?  it's near the speaker in these pics.

I would think that the clock would ground itself to the dash.

However, no such thing as to many grounds.

It should ground thru the dash. Just tighten that little bolt?

[marcapra]

I think that little bolt is meant to hold a ground wire.  So I'm going to run my glove box light ground wire to the clock bolt, and run another ground wire to the dash from there.  I'm not sure that's how it went originally, but it might be good.
