I'm working on a Stern Magic. I have several switches not registering - left slingshot, Stand up target "C", and drop target 1. At first I thought the problem might be in the switch matrix. But drop target 1 is not in that row - Drop target 2 is in that row and it works fine. (Drop target 1 does not register)
Then I checked continuity and found the white/brown wire is connected to DT 1 (not DT 2 as shown on the schematic). So the problem probably is in the switch matrix.
I could switch the wires from DT 1 to DT 2 to match the schematic but DT 2 only has one switch and DT 1 and DT 3 each have 2 switches.
What would you do?
