MRC AD 520 Auto Reverser question

Discussion in 'DCC & Electronics' started by trainsteve2435, Oct 28, 2006.

  1. Can someone please tell me how to hook up the MRC AD 520 auto reverse unit on a reverse loop? It has 2 red wires and 2 yellow wires. I have had this unit for a couple of years and i have lost the paper work that came with it. I have created a reverse loop on my cross over and just now realized it, so i need to hook this unit up. Thanks!

    I don't think you can hurt it... Try both reds to the "mainline" and both yellows to the reversing section.

    Comething tells me MRC has those instructions online.

    I remember it was the opposite of a DPDT switch.

    I am working on a reverse loop and I will be using the MRC Auto Reverse Module. The directions state to wire the red wires to the main line section and the yellow wires to the reverse loop section. :wave:
