Good morning, out on a limb here as I am very out of my depth in terms of knowledge.

This is a Morley Vector Zero Two speed controller for a model railway. It has two internal transformers to step down from UK 240V to 12ishV track power.

The component causing trouble is a "Formers I-EI 35X3/4" from Clairtronic Ltd and upon trying to use the controller yesterday, I think I shorted the track power and backfed into the controller. I have disconnected all connections to the controller and still get a light on the CDU and Red Reverse for Main Line and Loop on the control board.

Any help and advice would be muchly appreciatex, thanks in advance!
