train america bottleneck r2 board

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.

Thanks gun... I'll get you a picture of the rest of the board in a few days.  Came down with a bad cold and havnt been down stairs.  I'll send it though.

Thanks again!

Remember, those horizontal motored Atlas switchers sucked down a lot of juice.  I'd check the motor stall current to see if the Blunami 4A board will handle it before making the switch.

Gun,

Found "MOT" port on the bottom of the board.  I assume one post goes to each side of the motor yes? see photo

Troy

Yep, that's the place.  You can see the heavy traces coming from the driver triacs.

Thanks again!  Probably work on it this week.  Finally starting to feel a bit better.

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.

Troy

correction

it apparently WASN'T needed for movement

I believe those are the battery clip connection, apparently they didn't feel they needed a Railsounds battery.

gun.

Sometime over the past few years you mentioned to me where to get the small 2 pin male/female connectors for hooking up ERR, lights and such.  I can't track it down and I need to order some. 

Thanks again,

Troy

The ERR boards have JST-EH connectors.  Here's the whole list from Digikey: JST-EH connectors at Digikey.  You'll find the matching pre-crimped wires on the bottom of each product page.  You can also buy the contacts if you have the ability to crimp the wires.
