recently purchased new class 143 arriva trains wales from real tack models. Had it chipped but internal lighting does not switch on and off. My research has brought up conflicting info. That it does toggle on and off and that it stays on constant on dcc.
The chips used are lenz standard plus - which didn't work properly on the model and now has a hattons md4. Model works on this chip and directional lighting toggles on and off but interior lighting is constant. Any help will be most appreciated
