decoder issue?
Posted by Swayin on Wednesday, February 2, 2011 12:28 PM

My P2K H-10 44 has developed a weird hiccup ... when I choose its address, it starts going, then quickly, within inches, stops. Then starts again, goes a few inches, and stops. It's sounds do the same thing: the startup sounds when ti starts, and the shutdown sounds when it quits, and inch or two down the track. any ideas?

Swayin,

Is it consistent over any portion of track you run it on?  First I would clean (degrease) the track.  My Atlas HH600/660 is somewhat susceptible to dirty track and has done something similar to what you've described.

If tthat doesn't change things then I would perform a factory reset of the decoder.  The sequence for a QSI decoder is the following:

  • CV49 = 128
  • CV50 = 255
  • CV56 = 113

Hope that helps...

Try a decoder reset and see if that cures the problem.  And make absolutely sure your track and wheels are clean.

One, albeit not likely but possible cause could be a loose wire.    Was it dropped?   The other suggestions are more likely

As noted earlier, that's a classic QSI decoder symptom.  I've had 2 do the same thing.   The reset should have you running in no time.
