Sven,

I'm clear that this is just for the light bar, this coach has no motor so stay alive is not important here.

Cheers
Dave

I got that, ha ha! I was just making sure no one would start using this capacitor to blow up their trains.  :beers:

Stay alive for the decoder is important, if you have unreliable power to the decoder installed in a coach , which would be the case if you are getting light bar flicker, the decoder will need the stay alive to keep it operational and the stay alive I was referring to will also provide the back up power to the light outputs from the decider, not just to a ( in this case non existent) motor.

If a capacitor is installed on the light bar and a decoder has been attached to the light bar, the capacitor will catch interruption of the power from the decoder to the light bar.

Unless you use the decoder to create light effects, but that you can also achieve by removing the capacitor and not cleaning your track too well.  :laugh3:

Hi Sven, hope you are well.
My point here is that the decoder itself needs a reliable power
supply to work properly and the capacitor on the light bar canít do that ( correct me if Iím wrong).

Yes, you are right that a decoder would need reliable power, but that is the case if it is connected to a motor or a sound decoder. A motor or sound will stop immediately if it doesn't get power for a fraction of a second. But if the decoder is not feeding a motor, but only the light bar (as is the case with DCCDave's issue), then connecting a capacitor to the light bar is the free and working solution. If you add a Smart Powerpack/stay alive to the decoder, you get the same result, but you unnecessarily spend more money. If the light is being fed by a decoder or just straight from the tracks, that does not matter. If there is interruption from the track, with or without the decoder inbetween, the capacitor connected to the light bar saves the day. When the interruption has passed, the light bar would get power just the same, directly from the track or again from the decoder.

Unless I don't understand your point correctly?

...assuming the decoder correctly restarts in the same state it was left in before the power interruption. I am not sure that all of them do. Or does not get corrupted by intermittent power, that would be my concern .

Iíve never seen a decoder that doesnít retain its state during momentary losses of power.
