The coil shown in your pic is the reset coil. You activated it so the disc is all the way counterclockwise.
The notch looks to be in between the 10:00 and 11:00 position, so we'll call it 10:30.
When totally reset, it actually suppose to be relatively between 7:00 and 8:00, so around the 7:30
position. When totally reset (all the way counterclockwise), the contact should fall in the notch after
5 step ups from the step up coil that's on the backside of the Light Box Advance Unit. It's on the backside's
bottom right. This opens the set of contacts when the maximum of Wows (5) are shown on the backglass
and cuts the circuit to the step up coil..
