Hello,

 

I am hoping some light might be shown on this gremlin that apparently lives somewhere under my layout.  I will try to make sense of its symptoms.

 

first I have all four channels being used, the two that power my main line are powered by the Mighty Z-4000 a fierce foe of the Gremlin, the other two channels power the lower line and the yard.  This is supplied by the steadfast Lionel KW who has met the beast in battle long before the Z-4000 ever was known. 

 

I use one 24  post MTH board for each channel were my leads run every 10 ft of track. 

 

THe gremlin strikes randomly and without warning or sympathy.  From time to time the "Check Track" message appears, sometimes it does it on the main line sometimes it doesn't.  Sometimes the Gremlins ally the "Engine not on Track" makes an appearance, but in this case the engines all still start and run.  when this happens the engine speed control works fine , the whistle and bell and detail functions cease to work

 

One odd case is with a FM trainmaster and less frequent is a premier GP-7, when the "CT" message comes on the various lights/smoke will turn off on their own. 

 

I still need to get Barry's Holy Grail which I hope will defeat these demons once and for all, but in the meantime, can anyone help this poor subject of the MTH kingdom?

Bill,

Barry's Holy Grail which I hope will defeat these demons once and for all,

Yes, it most likely would. Start on page 147, Part IX - Troubleshooting Problems.


This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!

I thinks that's your problem. Do you have  the center rail insulated between leads(blocks?) and  if so  the 10 foot blocks are too short.

 Place magic light bulb on terminal block and make the  blocks in the 20 to 30 foot range.  It's not that hard to test, unscrew    the "hots" from  terminal block and add  back  one to one ten foot section,  for the next ten foot section jumper the center rail from the first to the second block with alligator clips. You can leave the outside rail connected  for testing.(signal test)

 

Anyway that's what I would do. good luck.
