thanks for the replies, changing cv29 to value 6 did the trick,thanks again.

the engine runs perfect in dcc mode, but will only make idling sounds on a dc track,using a tect II transformer, which works fine for any dc engine. won't do anything at any throttle setting. any ideas?

thanks so much, that did the trick, it is strange that my bachmann 4 6 0 was easy to change the address, like all the other dcc engines i have now, only the Climax engine was a problem. thanks again, i will print this so i don't forget.

i have changed address on other engines with no problems, but this one ,bachmann spectrum dcc climax engine, won't respond except to factory settings. suggestions? i have a MRC prodigy system. Jim

this is a bachmann 8 pin decoder with speaker it say bachmann on the pcb as well as the package it came in,this was a factory replacement item to give dcc and sound to dcc ready trains like my 2-6-0 mogul. all worked briefly until the wiring came loose, and i am not sure where the 2  speaker wires go? i tried going by color but no luck.HELP!   Jim

i bought a bachmann sound decoder on ebay new in package, in the process of installation in my tender,i broke the speaker wires loose from the circuit board. i soldered them back where i thought they went, but when tested, the  engine moved but no sound. is it color coded, or is there a wiring diagram to go by? the decoder has AE 32019 on it. thanks for any advice.

thanks for all the replies,this engine was part of a group of train items bought at an auction for $12.if Bachmann would send me a new engine for $25 in exchange for the old one,what a deal!i have many Bachmann engines and like them very much.where can i find out the details on this program?Jim

i recently got a Bachmann ho engine that has the old style rear drive motor that stands up in the frame.even when putting power direct to the motor,it won't do anything.any suggestions,other than make a dummy unit out of it?i fear someone has run it wide open and burned it up,it looks good,hate to give up on it,HELP!!!

thanks for all the help,this morning,i rotated the 8 pin plug 180 and guess what!!!! i have lights!thanks again,a nice engine now sounds and looks great.   Jim

i just put a sound decoder,supposedly a bachmann replacement item,in my ho 4-8-4 class j engine,when i ran it on dc,lights worked fine ,added dcc ,now no lights,what happened?it is a spectrum model,do you have to change the bulbs and if so to what? HELP Jim

thanks for reply,sounds like good advice,what about the lights?they worked fine before in DC,did the switch to DCC fry them?changing the tender light won't be too bad,but very little room in the engine!any suggestions? Jim

i bought a sound decoder with speaker for my spectrum ho n&w 4-8-4 j class,plugged it in,train runs,but no lights front or back,do they have to be changed due to voltage increase on dcc?i am using a mrc prodigy express,also what is the best way to mount the speaker,tender has place for it,but how to secure speaker with best sound quality?any help is appreciated.one more question,how do i  mount the extra circuit board?secure it to the tender weight somehow?
