I have been working on a Telechron Electroalarm for about 2 years. It has a good motor but the coil is defective. I finally found a good coil for it in a derelict Telechron alarm clock that had a built in light. This coil will make the rotor turn and the defective rotor that came out of the donor clock is identical to the original rotor in the Telechron.
Here are my questions. The original coil had no identifying marks, had 4 wires. One set read at 1.3 ohms, the other set was open. The coil I plan to use is marked with a 52, has 4 wires, one set reading at 1.7 ohms, the other at 885 ohms. I believe the pair that reads at 885 is a step down for the light, it puts out 3.3 volts when the other pair of wires is connected to an AC outlet.
Will this coil work correctly in the Electroalarm?
Any general advice also welcome.

Thanks for that. The electroalarm has a second coil for the bell and a somewhat complex circuit for the alarm that I am just figuring out. I'm hoping that by replacing the coil with a good one and restoring all the original connections, all functions will be revived.
