Hi. Has anyone had issues with lighting on the latest Dapol O gauge Class 122 Bubble car ? I have installed a Zimo DCC sound decoder and the lights at number one end do not work. The lights at number two end are fine. The lights work at number one end if I press function 12 ? but only the white lights, no red lights when changing direction. The chip works fine on my OO gage Dapol class 122. I have tried several other non sound decoders (Bachmann 21 pin) with differing results, mainly white lights at number one end stay on all the time. I am completely baffled, hopefully someone will have a solution. I guess a CV change is required, but dont know which CV needs altering.
