Algonquin RS3 Soundtrax Install

Hello Everyone. I just finished up installing a Soundtrax Tsunami Alco 244 decoder in my Atlas RS3.

digitrax dh166ps installation in a proto-2000 e-8 that has an 8pin socket

Having trouble getting headlight to work.  Had to place the green wire on the empty pin for the mars light which works fine.  Digitrax could not advise any further.  Has any one had this problem and if so what is the solution.

Shark attack -- mounting a Tyco shell on a Bachmann chassis

Has anyone tried mounting a Tyco Sharknose shell onto a Bachmann Sharknose frame/drive?  I have an old Johnson Wax set that I'd like to get resurrected, but the idea of trying to tune up the Tyco to come close to DCC seems to be a lost cause, and a Bachmann DCC-already drive seems like a much better idea -- if it fits.

Thanks in advance,

Getting volts but no amps on reverse loop

I have a PSX-AR Auto Reverser to power the reverse loop with the appropriate gaps and it is powered by a Digitrax DB150 Booster. On the mainline, with a RRampMeter and a taillight bulb clipped on as a load I get over 12 volts and 2 amps. When I test the loop I get no readings. But when I unclip the taillight bulb and just use the RRampMeter I get a reading of over 14 volts and 0 amps on the loop.

DCC polarity tester

MRH Note: Why DCC polarity matters ... at booster district boundaries or at reversing sections or turnout frogs, if you have the DCC polarity/phase wrong, the locos will short out and refuse to run across the rail joints!

A few weeks ago I posted a schematic for a DCC polarity tester on another thread. I don't remember seeing this anywhere, but I doubt I am the first to come up with it.

Hare, trigger rail and reversing loop

So I have a Wabbit - two hares - that I am planing to use to throw a turn out heading into a reversing loop so I can get continous running out of a loop to loop layout in N scale.

1.  I'm still not clear on how the triggering rail thing works, how does the hare know the engine has hit the trigger rail? What is detected?  I'm assuming the trigger has to be far enough away so that the tortoise has enough time to move.

Using DS64 Inputs and Crossing Flasher

I am looking for guidance on how to wire the optional output (shown as Item J on page 20 from Atlas Signal Control Board - link to manual is below) to the DS64 Input to provide the input to activate the flasher circuit in the DS-64.

Supplied Power AC Filter

Would adding a supplied power AC filter of some sort be recommended for large DCC set ups? We set up at convention centers and at one of these I could stand on the power cord that runs across the floor and feel the power. It was like water running through a pipe. Made me nervous if our system was at risk.

Ditch lights.

A question for any and all willing to give me some ideas   Ditch lights.  I've gotten in the habit of trying to add ditch lights to a loco that I fix up, add DCC to, or just refurbish, DC or DCC.  What are you guys using?

I've gone through a pile of tiny incandescent bulbs trying to find the perfect mix of brightness and resistor.  Maybe I should go to LED's ?
