I have a problem with directional lighting with my Bachmann 2-car DMU.
The power car has a Zimo MX648R which does the sound, and switches the front lights from white to red depending which direction is set by the handset (NCE PowerCab).
The trailer car has a Lais 8xx00nn non-sound decoder just to operate the lights. When I fitted this about a year ago, all worked well, then recently I noticed that the red lights stayed on irrespective of direction.
I've linked up JMRI to the test track and tried to modify the decoder settings there, but it seem to give no changes when I reset the 'function on running forward' and 'function on running reverse' options, I can't get the lights to switch over when I change direction on the handset. Both chips have the same address, and have done since originally fitted.
Any ideas? Thanks in advance!
