The lead car took 30 mins to provide a good working unit. Then the

One of the decoders ended up refusing to drive anything although still
There must be a switch sequence which Bachmann decoders obey to
disable lights (apart from the rather obvious on/off control and the
function 0 select). It must be related to the "go to address 03
And yes I have verified the wiring etc and run the system using other
decoders! Is there a hidden secret known only to the trade in which
Bachmann 36-553 decoders misbehave so and why are they suddenly so
