I have a strange problem with the RS-11 engine in for repair. All functions in TMCC mode work as they should, but if I increase the track voltage above 12 volts the headlights and marker lights flicker. If I run the engine in conventional mode the lights stay bright and flicker free.
Have changed the R2LC radio board, same problem.
Any other suggestions?

Antenna grounding out? Causing it to not see a strong TMCC signal? G
Thanks G
Will check that out.
Also changed the power supply board, no change with the flickering lights.
When the lights flicker, can the engine accept any other TMCC commands? IE, if blowing the horn, does it stop when the lights start to flicker?
I have a RS11 (SP, same vintage as your NH) that operates correctly in reverse, but forward is an issue. The antenna was grounding out like G said...
All other commands work as they should, the lights reverse direction on command, but flicker with voltage above 12VAC. Will check the grounded antenna idea to day.
Do they come on after time? I have a Lionel Erie Pacific that does the same thing. The front boiler markers lamps will not come on until I run it around the layout a bit. Sometimes they will blink rapidly until I hit the soft reset. (Aux1 0)
They come on after addressing the engine number and Aux1. They turn off and on with Aux2, and flicker at voltage above 12Vac.
