runs fine
railsounds works great in one direction
when I switch directions I get static
never had this happen with any other TMCC/RS loco
any ideas where to look?

Could be a loose wire or it could be a cold solder joint. i would check the wires first, but if it's a cold solder joint (not soldered securely), then you might need a tech to look at it if you don't work with electronics.

thank you
I'll take a look at the wiring....and maybe hand it off to a repair person if I don't see anything obvious
Jeff-
That's a weird one... does this behavior happen in both TMCC and conventional modes?
There are a few basic things to try. Test to see if things improve after each step.
1) Reprogram the TMCC electronics. The reset code for those locos is a 6.
2) Remove and re-seat the three modular boards attached to the motherboard -- R2LC, RailSounds power supply and RailSounds audio board.
3) Remove and re-seat the two chips on the opposite sides of the RailSounds audio board. I recommend you purchase a PLCC chip extractor ($5 or so on eBay) to do this.
Let us know if you have any luck with the above.

Denny and Todd,
not sure what actually fixed the problem 
but it works now.
I powered up to confirm I still had the issue and then cut the power.
I took off the shell and made sure there were no places where wires might be pinched, checked all wires for connection, and reseated the boards.
I then applied power and now the railsounds works in both directions.
so, it was at least one of your recommendations that did the trick.
thank you for taking the time to read and post suggestions.
Jeff
