Otto,
Per the drawing pic that both you and Dan provided, the switch in your pic is flipped 180 degrees. Per Dan's drawing the terminal with 3 screws for ammeter are on the left. Per your pics the terminal is on the right and with two screws missing. The terminalin question for instrumentation and ignition lock light is out of sight in your pic (somewhere lower left of your pic).
