Anyone have a wiring scheme ? Wires were crumbling so we decided to replace them. Now I'm not sure how the wires go. Any help would be appreciated

I don't know what's it's for, but you didn't specify what you were looking for...

It is for a fire alarm circuit.....
TH1 is used as a heat sensor. the 555 is an oscillator and uses t3 to drive the speaker.

The photos don't give much but generally it will just be a switch in line with the coil. Straight series wiring.

Think I've got it figured out. Replace all wires, and figure out how to reassemble. A lot of work for a 1939
