I removed the light board and connected pick ups to the motor leads and all works fine. It appears the MARS light board, photo attached, is the problem.</div> <div style="clear:both;"> </div> <div style="clear:both;">So I guess my question now is, does anyone know if these are still available? I'll start calling around Monday.</div> <div style="clear:both;"> </div> <div style="clear:both;"><img style="display:inline;" alt=" " width="281" height="198" /></div> <div style="clear:both;"> </div> <div style="clear:both;"><img style="display:inline;" alt=" " width="210" height="140" /></div> <div style="clear:both;"> </div> <p>[/quote]</p> <p>Check out the sticky thread at the top of the general discussion on how to post photos.</p> <p>Walthers probably does not carry the original P2k Lightboards anymore.  Your best bet would likely be finding an aftermarket decoder that has a mars light effect programmed into it (I believe this is a thing, I dont know for certain because my railroad did not use Mars lights). </p>
