Below is a picture of part of a Pratt & Whitney R-1830 radial engine. This is the engine that powered the DC-3, C-47, and other aircraft. I have labelled a few parts but there is one part that I am wondering what it is. It is the wire to the right of the spark plug wire in the picture. Does anyone know what it is for?
