Hi Thalys,
hmm, you are right! I remember that I´ve translated the Tipps&Triks a while ago, but - I also do not find it here in the new forum...
The easiest way to check, whether you got a new or an old Mot-decoder ist the direction check:
Put on a loc onto the tracks: direction forward!!!
Pick it up and change direction via the loc control.
Place the loc back to the track and drive.
a) If the loc has noticed the change of the direction even it was powerless, then a new Mot-decoder ist build in.
b) if the loco still drives into the same direction (and therefore did not notice the change of the direction) it´s an old Mot-decoder.
Hope this simple check helps.
Regards
Rüdiger
