I need help identifying the item in the picture below. It is some kind of coil connected to two blue wires. The coils is mounted in an old and rusty intermatic sprinkler timer box so I think this was an after thought by a PO. The box is mounted next to where the umbilical enters our 1971 Sovereign
and the blue wires lead inside. I have tried tracing where they go but no luck.
What is it ? Can I get rid of it or replace it with something less obtrusive ?
Thanks for any help, hints etc.
