Ok so I tried to program a new Bachmann On30 Connie last night, first time I’ve tried programming anything for a couple of years, I’m using an MRC Prodigy BTW. At first I suspected there might be a problem with the Connie Decoder then I tried to program a new decoder in a Shay, with equally poor luck. The older locomotives work fine, but I’m not able to program a new one nor am I able to read a decoder in an existing install, I suspect the problem is with the programming track, any tips or suggestions?
Maybe Stanley can help? Who knows but him what optional design criteria were included in those by the Technical Advisor?
Bart,
this from a different forum
MR said:?? do the engines run on default address 3?
The Bachmann decoders are notorious for programmign problems and sometimes need a 1K resistor across the rails.
Well I am not sure I can help much as I do not have a lot of experience with the Prodigy. If you had a Digitrax system Hans suggestion would be correct as some of these systems can not see high efficient deccoders but I have never see this discussed with the Prodigy.
Since you can not read anything I would check to ensure your programming track is clean, is totally isolated and that the wires are firmly connected to the Prodigy’s programming track output.
Make sure everything is working with a known good install before trying someting new.
Not sure if that is any help or not.

OK…Both locomotives work fine on Default Address 3…so the locomotives and decoder install are not at issue…Luckily MRC has the manual online http://www.modelrectifier.com/resources/trainSound/1406_web.pdf
So its down to programming…Or lack thereof…I recall it was really easy the first time I did it …I just don;t remeber how…
Also some tips and tricks from MRC…so what am I missing?

Two/four digit addressing problem?
Huh? Say Wha?
The fact that the decoder runs ok on DCC on the mainline has little to do with programming on the programming track. (I’m assuming you are using the programming track).
Some sound decoders need higher current. There are several “programming track boosters” available out there.
First try to turn off lights or anything that is directly across the rails.
Next try a booster.
clean track and not on rollers sometimes helps.
Whose decoder is on the loco? (bachmann does not make decoders AFAIK)

Does the decoder have a storage capacitor?
LGB and older Zimo decoders need the power storage caps switched out and a motor tied to the decoder in order to program them.
I assume other manufacturers decoders could have the same issue.
