In the middle of putting a Loksound micro into a Bachman tank loco and i need some advise on installing LED's for headlights.  I have mini LED's that are listed as Forward current of 15/20 ma and voltage of 2.8 - 3.4V.  Attaching these to the Loksound mini what size resistor should i attach.  Does it go to the Cathode or anode side and does cathode or anode go to the blue wire ground on the Micro decoder.

Thank you all for your help

Picked up a Scale Trains Operator w/DC only. Installed a TCS-T1 decoder in it that I had laying around.  Put it in a consist in the lead for the lighting effects with a sound unit trailing. Headlight is nice and bright, but can't get the ditch lights to work.

I am thinking maybe remove the wiring from the board going to the ditch lights and attach to new decoder. T1 says it's a two function. Does that mean the green & purple wires are of no use?

For the last 17 years or so I've pretty much just used NCE's D13SR decoder.  Until recently, it has had everything I've needed, good motor control, four mappable functions and affordability.  After I finished my rotary dumper and was loading more coal trains, I found NCE has a hard time with the sustained counting ties speed loadouts require.  Somewhere along the way I have two TCS decoders and I found they work well because they have BEMF.

My Prodigy Wiress Remote has (4) rechargeable AAA batteries (BTY 1000 - HW-IN).  I can charge it fully, turn it off, remove the connecting cable and leave it sit unconnected and not used for several days.  Over a period of less than a week, the batteries will run down to zero level.

Is that normal for rechargeable batteries, are mine defective, is there something in the Wireless Remote drawing them down even with it turned off, or what?  Anyone know what this is telling me?

Thanks for your help.
