My new EXP switch circuit board came in today. The other had a loose resister. I had been a bit rough on it while I was wiring it and testing it. I could have fixed it, but was afraid something else might be loose as well.
I disconnected the old board and left it below the new one. I rewired the unit as I installed the new one. (I'm doing away with the molex connector for the wiring.) I think my goofy idea of having a molex connector makes it more confusing and there are more chanses for problems. So, I'm connecting most of the wires directly to the device.
