Not exactly an amp question, but you guys will know.

I have a relay that was removed from a Johnson KW matchbox. I know the Matchbox relay operated from 115 vac, but the relay is not an AC relay. I suspect that at some point the Matchbox contained a rectifier and possibly other components.

I tried the relay on 32v dc and that was enough to hold it, but not pull it in. 115 vac just makes it hum.

I suspect it is a 115 V DC coil. Does anybody know before I destroy it with my experiments?

Part no. is EF Johnson 22-1153 or AEMCO 51-2595.
