Need some help with the arm EOS and the normal position of the 3 blades. The one I'm fixing had a broken bracket holding the arm EOS, and fabricated a fix using a small piece of wood to hold the broken bracket together. I'm following the schematic to see how to position and correctly adjust the 3 blades.

The "arm coil sw make at EOS" seems like the outer switch from the broken bracket and it's supposed to have yellow on one side and black-w/white on the other side. Since it says "make at EOS" I'm assuming it's normally open until the arm fires to close it. That covers 2 of the 3 blades of the arm EOS.

I haven't yet found the 3rd inner blade with the roller yet on the schematic and not sure if the 3rd inner blade is supposed to be normally open or normally closed with respect to the 2nd blade?
