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?

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

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.

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!!!

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

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?
