MRC ALCO PA decoder with sound

[UP SD40-2]

Well I have 2 brand new Athern RS-1's not even out of the box yet that I ordered 2 decoder boards for and to tell you the truth I'm a bit nervous about opening them up let alone installing the boards. So a bit of a well documented how to would be much appreciated.

Lynn, i dont have a tutorial on installing decoder "boards", but they are easy to install .

Once you get the shell off the engine, you will see the cicuit board(providing the engine has a board, Ahtearn BB for example do NOT have circuit boards), place your decoder board next to the engine, so its in the same position the circuit board in the engine is in. look at the wires going into the engines existing circuit board, and take note on where each wire goes into it.

now take the wires off the cicuit board thats on the engine, pull the board out, now place your "decoder board" in the engine, and connect the wires to it, exactly in the same places the engines original circuit board had them, THATS IT

Believe me, its MUCH easier then it sounds, really .

If you have problems, and have a way to post pics of your progress, DONT WORRY, we'll walk you through it .
