New wiring for old FW foot pedal
I'm cleaning up a 1955 FW and the foot pedal just barely reaches the ground. The wire coming out of the pedal was wrapped with adhesive tape so I know somewhere down the line someone shortened it up.
I ordered a new cord from sew classic but I can't tell which side of the wire is + and which side is -. There isn't any printing on the cord. I think I remember someone saying that the printing is the + side but since no printing.... no help there. The new wire is copper for both sides.
The old wire had red/copper on one post ( I assume +) and black/silver on the other post (I assume -).
I don't want to burn out my pedal. Can anyone help me?
