Re: 54 Convertible Turn Signal Issues

If you need to or decide to tear into the switch here are a few photos of the disassembled switch. These were taken by a poster from Canada who unfortunately passed a few years ago. I am sorry but I cannot recall his name or car at the moment to refer you to his project blog for more details on what is needed or anything to watch out for when taking the switch apart.

You can see the terminal positions as supported by the fiber piece on one view and the slide portion with the triangular contact plate that makes the connections on another. I colored in the terminals on the third and fourth photos to match wire colors and show how the mechanism moves the triangular contact plates to connect the various terminals. The wire colors were fairly consistent over the years and their full connections are shown on the simplified drawing of the turn signal circuit posted a few days ago.

If the fiber has warped and any of the terminals are depressed or otherwise out of position or if dirt or corrosion on any of the terminals has deposited, the switch will be intermittent or not work at all.
