Product Support for: Mobile Decoders -> 1.5 Amp HO Scale Mobile Decoder (DH163D)

Application Note: Walthers/Life-Like F7 H0-Scale steps needed for the DH163D DH123D decoder installation. Remove packing protectors screwed to coupler pockets: Carefully remove shell by spreading sides at side windows: Here's an alternate method for removing the loco shell - our F7 unit had a particularly stubborn shell. In place of the X-acto knives pictured, we recommend toothpicks or something a little safer.. Remove DC Plug (or a DC Printed Circuit Board in this case) from the wiring harness: DC Plug shown removed: Plug DH123D or DH163D decoder to 9 pin wire harness and mount it as shown: Reinstall loco shell.

For example, if CV52 (the FX CV for F2), is programmed with a CV value of 034, the violet wire F2 function output will be a Mars light when F2 is turned on for this decoder address and the decoder's direction is forward.

Athearn Genesis SD70s came factory equipped with a Digitrax designed light board. The board is NOT a DCC decoder. If you want to add a decoder and have alternating ditch lights the following steps are recommended: 1 - Remove locomotive shell; 2 - Remove dummy nine pin plug from wire harness and insert Digitrax DH163D on the harness; 3 - Remove the wires of one of the ditch light bulbs from F1N and F1P and solder them to F2N and F2P; 4 - Program CV51 to 106, CV52 to 107 and CV63 to 40. 5 - Reinstall locomotive shell.F2 on ...
