I cannot get a reading from the Gen2 MCU for its detent to limit switch test.It comes with this plus a neat detent on/off pulse width test. I adjusted the detents until I am getting roughly 25ms on/off. This seems to have no effect on selection. I sat down, again, with schematic and my trusty Fluke meter and started tracing out the detent and limit switch circuits. They check good on the mech so I started checking continuity through the mechanism cable to the PCC where it goes to plug J3108. Pins 5 and 10 are basically a loop through the mech limit and detents and back to the PCC.The MCU depends on these two wires to count ( the count consisting of on/off pulses) and thus tell it where the mechanism is. I pulled those pins and soldered the crimp to the wire in case of a loose crimp. I did the same for pin 1-ground, pin 3 12v, and pin 4 the clock generator. I will look into this clock generator more later. How did I get good at Seeburgs? Doing stuff like this for 30 years. Comes a problem, no one to turn it over to so I fix it or junk it. I’ll choose fix please.
