Ammeter heating up.........

I do understand what you guys are saying. Perhaps the rubber isn't the best thing to replace it with. But also with the connections being tight I haven't felt it get hot again. When the dash comes out of the car for the final resto, I'll update to something more "correct".
I think the main point here I was trying to share is the failure / crumbling of the dried out original material, leading to the looseness at the mounting points and causing the heat. I was thinking there isn't anywhere near as much heat when it's all good and tight. Of course, I could be wrong.

And yes if I smell rubber burning I'll know where to look!
