hi all,

i have a loco that i'm controlling in DCC mode, and i have this issue : i put in on my program track, which is directly connected to my MS2 thriugh a switch (so the main track power is off when the program track is on), so i have no interferences.

when i read a cv value from the loco (and cv number), it returns the value "0" roughly 60% / 70% of times, and the correct value in the other cases. could this be due to some bad wirings ? or is it more probable that there is a problem with the loco decoder ? the loco seems to behave correctly when used on the track, but i cannot manage to read its cv values even if i connect an (updated) CS3+ program track output to my program track. I click on "read all", it reads just 3 cvs, and then it stops with the message "cv read error".

thx for any hints
