QUOTE (Gary @ 26 Jan 2007, 12:02) <{POST_SNAPBACK}>Heh! Heh! I have to laugh. What about those companies who offer "DCC Fitted" or "DCC Onboard" and fit capacitors and state that you can operate your loco on both DC and DCC layouts. What are the implications of removing the capacitor in these circumstances for DC use even if one is not required for DCC?
DC or DCC is irrelevant for DCC fitted locos since the decoder is always in circuit. The motor is always being driven by the decoder and the capacitor will have the same effect (or lack of) whether you run on DC or DCC.

QUOTE You would suggest leaving the capacitor in place in such a circumstances?
As suggested, if it works, leave them in or, if it aint broken, don't fix it.

QUOTE And if you have no intention of running on DC would you susggest removing the capacitor?
See above.

QUOTE And what about those companies who offer decoders which can permit your loco to run on both DC and DCC? If you fit one of these and you do run your loco on both DC and DCC layouts what is the capaciter position then?

Would you suggest leaving the capaciter in place or removing it regardless?
See above.

QUOTE I do seriously want to clear this up once and for all and have an answer that is consistent for all conditions and circumstances irrespective of decoder manufacturer!

Is this actually possible?
I have never heard of a case where removing the suppression components did not work. That is the only answer that can apply under all conditions. Otherwise there are too many variables in the choice of decoder and the type/quantity of suppression components fitted.

Suppression components should always be removed from power clips. They should not be confused with the filter components (Resistor and Capacitor) sometimes used on larger layouts.
