Problems with heavy mountain

[termite]

  I recieved my heavy mountain about a month ago. It ran great, and was very smooth. I parked it on an unpowered siding for about a week, while breaking in an other loco on DC. This siding has NO power connections at all and is separated from the rest of the layout by 1/8 inch gap. Tried running it tonight and it won't run on DCC at all, but does run on DC. What gives?

Dear Termite,
What decoder are you using?
the Bach-man

[termite]

Bach-man it's the one installed by the factory

Start over. Reset the decoder’s CVs to their factory set value.

To reset the CVs on a Bachmann decoder, write a value of 8 to CV8 using a unit capable of programming the decoder's CVs.

[termite]

Hunt, I already ried that. my digitrax system shows an open circuit, and gets no response from the decoder when trying to read CVs

lay a 1000 ohm resistor across the rails of your programming track
and try again, the loco is not drawing enough current for the programmer to detect.
the additional load of the resistor allow your programmer to work.

If you are using a Digitrax Zephyr --- try what rObert suggested.

Your issue has been covered many times by me and repeated by others on this board.

Workaround required to program a non-sound Bachmann decoder using a Digitrax Zephyr.

Workaround --- Place a 1000 Ohm resistor across the programming track. Remove the resistor after you finish programming the Bachmann decoder.

[termite]

Yep, tried that too, still got no response. Talked to a service tech today, on his recomendation, boxed it up and sent it back so they can clean out the gremlins

[Hunt]

termite,
Are you now able to program and run any another decoder equipped locomotives using your Digitrax Zephyr? If yes, what brand, locomotive model and decoder?

How long have you been using this Digitrax Zephyr command station?
