Recently a friend dropped  off 3 postwar Bascule bridges , 1 prewar. 1 postwar complete and 1 prewar in parts. He said  he had no luck trying to get them to work.   I've fixed a few in the past mostly servicing the motor, replacing bad wires, adjusting the layered contact assembly and the spring. Part I try not to mess with is the ears on the shaft which runs thru the bridge  To me this is the key component, in the wrong position it impossible to get it to work.It is a lot of work to disassemble the bridge and put the ears in the right position. Iv'e gotten a lot of literature on the bridge and nowhere have I seen a photo of that assembly. I do know they should be at 90o. Thanks to the article by  R.J. Luppold  The reason for this discussion is the lack of power from the motor (After 70 or 80 years is this a surprise for a accessory that was under powered in the first place)  Has anyone tried to have the field rewound ?  When I see armature, coils and fields that have that burnt look from overheating you know they are not working as intended. I know we get armatures rewound and the're like new. Why not the field? Or has anyone tried to replace the whole motor?  Just things to think about. Once again thanks to all who contribute to this discussion.
