QSI DC Operations Enhanced with Supercap

Supercap Wiring (ext. link)

An HO DC QSI user installs the SuperCap to a Revolution to hold up the sound when track power is off.

By Jim M.

Happy to report that the SuperCap install is a success. Sound runs for at least 30 seconds with no external power.

Now I can operate my trains and not the sound system. Works great when switching also.

Aristocraft Train Engineer is set to (C) for:
-Time delay when changing direction (This keeps the system from thinking I am trying to sound the horn)

If train is stopped and sound is at idle:
-The auto horn will not sound during change of direction (That's a good thing when switching)
-I can then operate the horn using the Quantum Engineer if desired.

I would recommend the SuperCap for anyone using DC.
