, i might be able to help you with the sound decoders

. i(currently)have 58 engines, ALL with sound, a few of them ARE Athearn "DCC Ready" engines:thumb:. Loksound, and MRC Brillance sound decoders will work in your engines. i am sure Soundtraxx decoders will too, but i myself think the LokSound, and MRC Brilliance sound decoders are better. announce1thats just MY OPINION(did i say thats just MY OPINION

).
YOU have three options to install a sound decoder in an Athearn "DCC Ready" engine:
OPTION #1
One bad thing about Athearn DCC Ready circuit boards is the 8pin socket on the circuit board is so SLOPPY, you cant just push the sound decoder plug in it and go, like you would on a P1K, P2K, or Kato engine. if you read the papers that came with that engine, it says to install a decoder/sound decoder "solder the 8pin plug into the 8pin socket on the circuit board", MY answer to this is...HA! GOOD LUCK!

i am NOT saying it cant be done

, but i have NEVER had good luck doing this:curse:. good luck not melting the circuit board

, or not getting solder to not connect at least 2 of the pins together

. you might be able to do it this way, but i prefer not to.
OPTION #2
you can buy an adapter to connect the 8pin plug on a sound decoder to the 9pin socket on the circuit board:thumb:. be sure and pull the mini circuit board out of the end of the 9pin socket first

. i am sorry, but i cant remember who makes the adapters

ops:, i think Digitrax does, but cant swear to it. announce1THIS WOULD BE THE EASIEST WAY TO GO! if you are a beginner, this way would give you the least hassles:thumb:.
OPTION #3
this is the option I ALWAYS USE when it comes to Athearn "DCC Ready" engines. NOT recommended for beginners, yet its not as hard as it sounds

. i take the wires off the circuit board, and throw it in the trash, cut the 8pin plug off the sound decoder and HARD WIRE IT IN:thumb:. WHY DO I DO THIS?

2 REASONS, 1- it gets the circuit board out of there and gives you more room for the sound decoder

. 2- it saves you the money you would spend on an adapter

.
**ALL SOUND DECODERS WITH A WIRE HARNESS ARE SET UP THIS WAY**
ORANGE WIRE= to motor
GRAY WIRE= to motor
BLACK WIRE= to left side of the trucks
RED WIRE= to right side of the trucks
WHITE WIRE= to headlights
YELLOW WIRE= to backup lights
BLUE WIRE= the common wire that goes to BOTH, the headlight and the backup light
GREEN AND THE PURPLE WIRE= are for optional lighting functions like ditch lights, mars lights, etc. unless your engine has these options, you wouldn't use these wires. just cut them short, and cover the ends to avoid a short.
EDIT: there IS a fourth OPTION...
i have done this before but i didnt want to post this, but after reading a PM sent to me(THANKS Thoroughbreed

), perhaps i should. Cut the 9pin socket off the wires coming out of the decoder, now cut the 8 plug socket off of the sound decoder. ALL the wires ARE color coded the same, so you could solder the decoder wires to the wires that was connected to the 9pin socket coming out of the circuit board:thumb:. i have done this on a couple of my dads Athearn DCC Ready engines. for a beginner, i guess this would be fool proof:thumb:. HOWEVER, to me it seems kinda senceless. WHY? you ask, I'll tell you why, you STILL have to solder wires, and by saving the Athearn circuit board, now you have ANOTHER THING to work around, while trying to find a place for the sound decoder and speekers

. to me, if i am still going to have to do soldering, i am not gaining anything by keeping the circuit borad

, so i just 86 the board. in some engines, its real tight in there, so making room IS important.
BUT, this way IS beginner friendly and will give you some experiance:thumb:.
announce1 KEEP IN MIND, all i have wrote above is how to install a sound decoder in an Athearn "DCC Ready" engine. FOR OTHER BRANDS, i would give different instructions.
HOPE THIS HELPED!

, i have Athearn BB's, Athearn RTR's, Athearn Genesis, and Athearn DCC Ready engines, NONE OF THEM requires the removal of the fuel tank to take the shell off. i am NOT saying it isn't possible that you might have to do that, since i don't own an RS-3 Athearn, but usually to get the shells off them you would pull the couplers and coupler boxes off, then there is 2 sets of "tabs" on the frame, one set towords the front of the engine, and one set towords the rear of the engine. pull the shell away from the frame in these to spots, the shell should come right off
