Hello, everyone. I am new to the board and only have about 2 months in the hobby. I recently picked up a Mantua Vanderbilt Tender. I opened it up since I am planning to re-label it from Union Pacific to Southern Pacific. When I opened it up I found this wiring and can not figure out what it is for. The screw in the middle is attached to some wipers that are attached to the front and back wheels. Not sure what the electronic component is attached to the weight. and from the component the wires that are spiraled are not attached to anything they both just end. They have not been stripped so I don't think they were ever attached to anything. Appreciate your help I will be attaching this to one of my steam engines and don't want it to blow it up.
