They're all tested on the bench before being packed, and specifically the capacitor storage is checked to make sure it works for each module. However, I have had one come back that a lead on the capacitor was loose from the board. The result is it has flicker as you observe.
I inspected it but didn't find anything. Not sure I could repair it if I did! I've never attempted repairing a board. Soldering wires to the regulator contacts is probably the limit of my microsurgery skills.
So I connected up a second one from the batch that I purchased. The second one does hold a charge, but for a very brief period. I am still getting plenty of flicker. However, I am going to turn my efforts to modifying the trucks and pick-up wires. I have other passenger cars of the same size and weight which do not have the flicker problem that this particular set has. I am convinced that I need to achieve more constant contact somewhere on the path from the rails to the regulator. That plus using these regulators should eliminate the problem.
