My 1937 Ruby has SF40 trafficators which I am trying to recommission. When power is applied the arm will not lift, although the light goes on. To check that the problem is not related to poor connections in the wiring system, I have removed the trafficator and connected it directly to the car battery with short wires.
When I try to raise the arm manually, considerable force is needed to move it through the first few degrees. Then there is a click from the mechanism and the arm jumps to the correct upright position with considerable alacrity and stays there until power is removed. It then drops to the correct down position.
Does anyone know whether there is something in the mechanism that I could fix to get the arm to lift from the rest position?
