So Sterling, you say the Tester is working on “all other Functions”, but you do not say which function, it is, that is not working???? It sounds like there is not much wrong with it. Should be easy to zero in on and correct. You are already over half way there. Let me know which function it is that is not working??? I may need a copy of the Schematic! Also can you let us have close up pics of the wafers in question. If he just disconnected the two wires, and re-connected them to an open switch on another wafer, that set of contacts would have to be in the same position on the second wafer as it was on the first wafer?????
