Hi

I am converting a Trix Nohab (22169) locomotive to Marklin 3-rail.

The wiring harness to the decoder board has been done in such a way that it is difficult to access the soldering point for the brown wires and I therefore wondered if completely disconnecting the black wire to the rear pickup would be an alternative to re-attaching it to the brown wire?

Thanks for any assistance.

Thanks for the suggestion.

I have converted a couple of old Lima locos to 3-rail and used both pick-ups as grounding for those. This is my first Trix conversion and I will keep to the same approach for that after all as you suggest.

Thanks again for the help.
