I have seen in videos on MR Video plus as well as on TrainmasterTV  and on the internet the use of flux for electronic soldering. Once at a Narrow Gauge Convention I saw a dealer selling Carr's Orange (I believe) flux which will make solder work better without corroding electronic circuits. I have looked online and not been successful. Where can one purchase flux made for electronic projects like Carr's Orange or similar?  Any other suggestion out there?

Hi all,

I have a steam engine in which I'm using a Digitrax DZ123 decoder for motor/lighting control and a Digitrax SFX006 soundbug decoder for sound.  I'm now trying to program them using the decoder lock feature and I'm running into a couple of problems.

I just installed a Loksound Select 6-aux into an HO Atlas C420 using the 8-pin plug.  The loco already had resistors in place on the leads for the factory-installed LED lighting.  The loco runs and sounds great, but I can't get the lights to work.  The Lokprogrammer shows that LED Lighting mode is enabled.

Any ideas what's interfering with the lights' operation?  Obviously, I missed something but I'm at a loss as to what it is.

I'm starting a new HO layout after a 20 year plus layoff from the hobby. I'm planning on using manual turnout throws where possible for economic reasons, but I'd rather not use Caboose throws because of their large size. Instead I'm thinking of using SPDT slide switches, wiring the switches to control the frog polarity. The appeal is that the slide part is very small and I can even cut it down smaller so it doesn't stick up above the scenery too much.
