I am having the worst day in a long time right now. I just got 2 DH163ATs from Walthers yesterday, and i went to go hook them up. the first one (athearn blue box GP38 ) ran well initially ( although i do need to clean the wheels) but then i stopped it while switching directions, and then put it in reverse, and opened the throttle, but the train didn't go anywhere. no ammount of pushing or coaxing got it to run. Originally i thought this may be a disconnected wire, so i unplugged the decoder from the harness and plugged it into the 9 pin plug on my brand new AMD103. for some reason, the rear headlight on the second locomotive blinked on, but the locomotive was not responding to the commands i sent. then i tried it on some fresh tracks so that i was sure there was current getting in there. I didn't do ANY programming to it whatsoever. the next project (Athearn RTR GP40-2) has it's headlight stuck on, and i think this may have happened in a short that occurred when i put it on the tracks. (I noticed later there is a tiny scorch mark on the wrapper, so i'm guessing this one is done to). The locomotive ran though, even if it did so awkwardly, but i know not all of my layout's tracks are the cleanest (lost the track cleaning block) I tried programming the adress into the decoder (so i could see if i could turn that light off), and so my Prodigey Express supposedly has the ability to put an adress right in. Apperently, it doesn't, because when i entered 3401 into the adress programmer, that definitely did not turn out to be the new adress. it twithced back, kind flashed, and then nothing but a full bright headlight. I have no clue how i can atleast get that decoder to work. I'm thinking about sending them in for repairs, but i don't want to pay another $32 to get these things working again, i could almost get a new decoder from some other manufacturer, because i've seriously lost faith in digitrax. I know the second one might be my fault, but the first decoder was set up perfectly, and then stopped working, no matter where i put it. is there anything i can do, so that i don't loose $64 in decoders?
