[Winky Dink]

Thanks, 'coot. I already took off the second can in a manner similar to what you described. On the first can I used a socket, so I couldn't see what was happening. Also thanks for the aspirin tip. Unfortunately my blunder gave me such a headache that I had already taken all the aspirin in the house. It wasn't easy scraping the wire that I could hardly see. This wire is also covered with what appears to be cotton thread, and I don't know for sure if it is enameled.

I'll follow your advice and see if I can divine a solution.
