I have an 0 gauge locomotive that has been built with a live chassis and insulated wheels on one side. It is fitted with an ESU V4L decoder. I can program CVs and the sound file works whilst the loco is at rest. When power is applied, the decoder cuts out. I have tried another V4L and the same thing happens. I have retained the track input wires and wired the decoder to an identical motor on the bench, and everything is fine. Can anyone suggest what my problem is? The loco runs fine on DC with no shorts. Does DCC not like a live chassis, even though it's insulated?
Thanks for your interest.
