Putting my 57 bird back togeather after a few years off the frame. All under the hood and the running gear is done and working. The dash is still out and the wire loom is hanging on the clips. Last weekend I put the switch back in so I could start it and get it off and on the hoist. Had some issues with stuck float and while I was starting and running to fix that, the resistor quit. Didn't think anything of it as it was old. Bypassed it and got everything running right. Last night I pluged in another one I had in the drawer (typical ceramic GM unit) started it up and everything worked fine. The resistor started smoking, I think it was from dust and being new (as in old but unused) but not sure. Before I get another new one from the Tbird suppliers thought I would ask what else would or might make one smoke. This one has run for 10 or 15 minutes and doesn't appear to get red, it just makes me nervous to have something that puts out smoke under the hood.
