Thanks, Mr. Lang. The circuit breaks are a surprise, because I have a schematic for the 1953 and they are not shown on the switch diagram. I guess they are considered an "internal" part of the switch. Wow. One more thing to check. I guess that is the "fuse" because the red 10 ga. feed comes right off the ammeter.
Anyway, thanks. Now about the button , I will have to go under and look again. You have pointed me in the right direction. I wish I knew where to find a picture.
