Gentlemen,

The attached picture is from an old Atlas "slim body" switcher.  This was picked up at a 2 rail show from a junk box and was in pieces.  The only one that seems apparent is the ANT would be antenna.  Can anyone tell me where the center rail, wheel and motor hook ups would be.  Also, the prg/run switch is currently in the upper left (green wire) but I can't be sure that's the proper spot.  Might it be really be in the SW spot?

I  tried one like this a few years back and failed miserably.  If I can't make it work, I will move on to a Blunami board if it will fit.

Top row: Rear Light --- Track Power...

Middle row, Rear coupler --- Antenna --- Front coupler

Bottom row, PGM/RUN SW --- Front Light

Obviously, Power is center rail red and outside rail black.

I don't see the motor connections there, but I'd have to see the whole board, there is obviously a place to connect them.  I've had several of these through here, and I managed to get them working, but it's been quite a few years since I saw one.

Gun,

Good news.  First try!  Coded in as #1 and responded to movement requests beautifully.  Next hurdle... nothing but garbled rattle static for sound.  I was thinking about doing a factory reset on the unit???

It seems possible that this was a conventional unit where someone was going to add this board.  I came to this conclusion when I saw that not only was there a speaker attached to this board, but there is already a speaker mounted in the body.  I am using the speaker that was mated with the board.

Also, take a look at the photo... those two clipped off wires my pen is pointing to (second photo is close-up).  Any idea what those should be leading too?  These are on the bottom of the board (same side as motor hook ups).  Any chance those need to run to something for the sound to work?  It apparently was needed for movement.  I haven't tried any lighting yet.

Buy the pre-crimped wires I bought the crimping tool and a thousand of the tips if I do ten two will be good and I will spend five minutes each getting the tips/wire loaded in the crimping tool.  When John told the forum of the pre-crimped wire leads I bought a thousand and haven't used the crimp tool since.          j

I confess, I use my crimp tool a lot, but when the connectors get a finer pitch than around 1.5mm, I use the pre-crimped wires.  The MTH 1.0mm pitch PS/3 connectors are next to impossible to crimp without a $500 factory crimp tool.  I get about one out of three doing those. Not much better are the 1.25mm pitch connectors used in Lionel Legacy at times.

OTOH, for the 2.5mm JST-EH connectors being discussed here, I crimp those all the time with near 100% success.
