I have an old Optimate 3 battery maintainer.
It came with a TM-72 AMDC adapter cable like the below. It is used to plug the charger in to a Hella style socket, or a cigarette lighter type socket by removing the red adapter that you see removed in the below photo.
The red arm that you see in the above picture folds out 90°. See below. I have never figured out what that arm is for. When I do a search I find many references to this plug, but no explanation of what this arm is for.
Does anyone know?
