Thank you, Greg. I would follow your suggestion, but I'm not about to give up all hope at the prospect of fixing a pair of leaf springs!!

I've cleaned those springs with three different solvents but they still won't make electrical contact. There is plenty of 'spring' in them to make a good contact with each other, but it's just not happening. I've never had this before. Ever. Ideally I'd like to remove this pair and examine them under the stereoscope, but that's not possible. The only other thing I can try (and I'm fast running out of ideas) is abrasive paper. I have the full range of grades here from coarse to ultra-fine. Does anyone know what these springs are made from? I don't wish to rub through some delicate plating and make the situation even worse!
