May I suggest that you try programming your 4-8-4 to address 03 before doing anything radical. A new decoder is supposed to be set to address 03 but that is no guarantee that it actually is. Use your E-Z Command and the instructions in your manual for programming a locomotive with an unknown address.
Another test you can perform without opening up anything is to attempt to run the locomotive on address 10 using your E-Z Command. This is normally used for running locomotives that have no decoder installed and while it generates a dc voltage, it does so by stretching some of the DCC pulses. The presence of DCC pulses will prevent a locomotive with a decoder from converting to dc operation so if your locomotive runs on address 10, it does not have a decoder installed.
I agree with not opening the locomotive to check out the decoder but only because the decoder is located in the tender. Swapping decoders to change performance characteristics is so common that I would be very surprised if Bachmann would refuse to honour their warranty just because you opened the tender. If you have any doubts about this, give the service department a ring and ask. (If you are in the UK, then by all means make use of the time difference - call late enough to get night rates but early enough to catch Bachmann still open.)

hi jim,
i'm located at auckland, new zealand and i think we don't have a bachmann representative here. i'm not going to do anything yet and will not try to swap the decoder and still awaiting reply from thefavoritespot. i'm surprise as they still didn't reply to me back. normally when i asked for an invoice for combine shipping they replied back within 30mins!
