hi! I saw information on a website about installing a cheap temp gauge on my rc nitro car. I bought the household electronic temp gauge @ wal mart. The web site called for me to remove the metal tube around the wires and attach the wires to my cooling head. The two wires were attached or encased in what appeared to be a small glass bead. They broke off of the bead, and now the gauge doesn't work. If I touch the two wires together, the temp changes momentarily, then goes back to not working. Is it ruined? How does it work. It was only 15$ so Im not going to cry about it, but if I can make it work, that would be great! Please help!
