HO Digitrax decoder in MTH ps2?

Sure, but I think you will be at the limit for the motor and current rating.  I imagine the board won't last long, especially if you stall the motors. 

What functions don't work on the PS-2 board?  May be repairable.  G

Thanks GGG.  I wanted to use it because it is half the price of their 4amp decoder.  I guess this is too much loco for that guy.

The PS2 loco runs fine conventionally.  The sounds start up at full blast but instantly go back to half-volume and stays there.  Twisting the pot has no effect on the volume.  The guy who sold it to me said  id for the locomotive cannot be located in DCS.

I was hoping to run this in DCC with my PS3 locos.

Is it CSX? I'd buy it.

Does it play shutdown sounds when you turn track power off?  I would disconnect battery and start up again.  Does the volume play normal?  If so, just replace the battey.  If not, if may either be Power Supply (repairable), or Processor (not repairable).  G

It was the battery.  I swapped out for a good one and now the volume adjusts normally.

Thanks for the advice, GGG.  I guess this purchase was a better deal than I thought.
