Fixing a kiln requires great skill

Or else good instructions and lots of dumb luck.

Two of the heating elements in Mary Ellen's big kiln haven't been working for a while. I replaced them a week or two ago -- after watching some videos on the kiln manufacturer's web site -- but they still didn't work. Today I attacked the problem again, this time with the help of a troubleshooting guide supplied by the manufacturer. I got as far as step number 1:
If all the elements on the same relay are out, try connecting that bank of elements to a different relay.
"Uh-oh," I says, "This looks like trouble." Nevertheless, I located the wires that led from the bad elements and saw that they both attached to the same piece of plastic in the switch box. "Well," I says, "I guess that hunk of plastic is a relay." Then I says, "Huh. There's another connector on that relay, but there ain't no wire attached to it. Oh, wait a minute, there's a wire dangling loose in the box, not connected to anything. I wonder what would happen if I connnect that loose wire to that unused connector."

Bingo!

Let's hear it for dumb luck!
