Gents, I have access to small piezo electrical buzzers that are quite lod at 3v to 6v. I assume (egads...) that I could hook one lead of the buzzer to the yellow wire, the other lead of the buzzer to a momentary SPST switch and the other side of that switch to the black (grnd) wire. I think the buzzer would sound when the momentary SPST button is pressed to "poll" the turnout. However I would only want it to sound when the voltage is pulled in one direction (really matters not which way as long as they all worked the same). How can I accomplish this? Would a diode between the yellow wire and the buzzer work?
I also have a few more questions about hooking up the turnouts. One is about connecting the wires from the turnout (grn, rd, and blk) to the mon-off-mon switch. Can I use solid core 4 conductor (only 3 wires used) phone cable for this? I know it is only 24 aug but is that enough? If so it would make wiring pretty easy.
thanks guys
