Decoder in Loco

I am in the process of converting my HO railroad to a DCC system and have bought an MRC Prodigy Advance system.  I have been trying to program a loco that I bought from Bachmann about 3 years ago (I think).  It is a K4 4-6-2 Pacific locomotive.  The Bachman item number is 84013 but I don't see it on your site.  I no longer have any of the information that came with it.  I need to understand the voltage requirements to program into the system (starting, top).  Can you tell me what decoder is installed in this loco and how I might find out the voltage needs?  Is the loco now discontinued?  Also is the decoder address likely to be the loco number (3750)?  I think it is.

Any help much appreciated.

No you are incorrect in making that assumption, as loco's default address is actually 3, as it is for all Bachmann DCC locos.

Here it is:

It has a Bachmann E-Z Command 1 AMP, 2 Function Decoder.
Starting Voltage is CV 2 and ranges from 0-31, the default value is 10
See this link to a pdf for more info: http://www.bachmanntrains.com/home-usa/ez_content/1_Amp_Decoder_Instr.pdf

I think your problem is that you are trying to address it by the incorrect address, try using 3 or 03, and see what happens.

And if that fails, set CV 8 to 8 and  try address 3 again

#84013 is the DCC ready K4 Pacific.

You have to add the DCC decoder yourself.

Good point, I completely overlooked that, DCC ready does not mean it has a decoder inside, it just means that a decoder can be easily installed.

OK. Thanks.  I took the tender apart and saw what I thought was a decoder installed but obviously not.  Two sets of wires run to the locomotive connected by a couple of plugs. I'll read up on the installation and see if I can do it myself.
Thanks again

What you saw is the PC board where you'll plug in a decoder.  To save yourself some grief, use the same brand of decoder as the system you have.  Most decoders will have some brief instructions on how to install them.  Make sure you buy a decoder with an NMRA 8 pin plug.  That will plug into the board in the tender.  Follow your system's instructions on how to program values into the various CV's.
