An acquantance of mine is sending me an HO Athearn Genesis Challenger to install a sound decoder in and I can’t find what type of decoder it takes.
It is from the 2017 run and is DCC Ready (ATHG97747). I’m assuming (shouldn’t do that) it would be an 8-pin variety, but I’m not certain. Anyone know for sure ?
My advice is to wait until you have the locomotive in hand. It could take any one of decoder interface such as 9pin JST, 21 pin, 8 pin or even the next 18. Do you want sound or just motor and lights? I recently did a motor only decoder for a friend that the documentation for the locomotive said NEM 8 decoder that actually took a 9 pin JST. That too was an Athearn.
As indicated, he wants sound - Loksound specifically. He’s not comfortable opening the engine up to look and online documentation seems to be scarce. I was hoping to get a jump on it and order the decoder now before the engine arrives and minimize my turn around time.
