I recently installed a sound decoder in a Bachmann 2-6-0 locomotive. All of the sounds appear to be working as they should.
Problem is that I have no speed control in forward and the engine runs at one speed. Also it runs faster in reverse and I do have some speed control.
I don't think I have reversed the motor leads. Any one run into this problem before?
Reset the decoder 8 to CV 8
If that doesn't solve the issues contact SoundTraxx Support.
Resetting the SoundTraxx decoder CVs to their factory default value is a two-step procedure.
1) Program 8 to CV 8 (can use either Service Mode or Operations Mode programming)
2) Cycle power to the decoder by turning power to the track off and back on
After about six-seconds upon restoring power the headlight and backup light will blink simultaneously 16 times indicating that the CVs were successfully reset. However, if sound or lights come on immediately upon restoring power, the decoder did not successfully reset. Repeat the two-step procedure.
