Someday I may be able to reduce the size of the photo of the Shay board so that I can attach it here and show where the two wires are soldered.  Meanwhile, here is a written description:

- look ar the side of the DSD Shay sound circuit board so that the word "SoundTraxx" is in the upper left.
- look below  the characters "B2TS", and you will see two small black rectangular components soldered to the board.  They have small bands on their left side.
- solder the blue, positive wire from the KA to the left (band side) of the left component.
- solder the black and white striped, negative wire from the KA to the right side of the right component (non band side). 
- it is best to pre tin the wire!
- I put a micro dot of Rosin flux on the component pad, and use an iron with a tinned tip and steady hand!

Above is a link to the photo of the Shay board from the forum, but I fear it won't work for non members.  I need to search for the photo in my computer . . .

Sorry I was wrong.  Non members can not enter at this time. Apparently they have had problems with Bots and malware.  Perhaps I can figure a way to post a photo of the wiring diagram here .  . .  One could also join that forum.

You might try the above link.  I believe non members can read but not post.

The TSU 1100 should be a perfect modern solution.  A current keeper can be easily added to it.  However, due to limited space, I would consider a TCS KA-3 instead of the Current Keeper.  RRPETE wants to add a keep alive capability to the old DSD board.  That board in ancient, but can still give OK service, especially with a KA addeed.

Also, I would treat all wheels and electrical pick ups with a contact cleaner such as CRC, to see if that helps, before adding a KA.

I would try a low luster (not flat) black.

I have had mine off.  A thumb nail can be a good tool for this, starting in any corner and working around the edg.  There are small plastic prongs in several places.  A plastic putty knife might also help.

Yes, I have a thread on the Railroad Line Forums in the On30 area with info on adding Keep Alives to some 0n30 locos!  It includes the old DSD-B2TSLC board.  Beware, it does require soldering directly to the circuit board.  I hid the KA inside the wood load in the fuel bunker.  I used a TCS KA-2 and had to hollow out the load a bit.  A KA-3 will be an easier fit.  It makes a big improvement in the locos ability to run at slow speeds without stalls or hick-ups.  The Soundtraxx Current Keeper would also work, but since it is larger, it would be harder to hide.  Regarding help from Soundtraxx on this topic, my experience has been that it depends on who you talk to.  The first person I talked to was  reluctant to help because a person could ruin the board with a hot soldering iron!  Their newer boards are designed to be compatible with Current Keepers, the old ones were not.  Finally,  you may have to search thru several pages to find the thread on the RRLF.

I have fitted Tsunami 1000s in both 4-4-0s and the rail bus.  The small 4-4-0 needed to have the underside of the coal load sanded a bit to make room for circuit board.  I put the circuit board for the bus inside the passenger compartment.  A smaller TSU 750 would have fit inside the roof but it had over heating problems.  Today I would use a TSU 2 or the Economi in both models.  They are smaller and have more features.

Also someone on the net fit a sound board from one of the Bachmann H O locos into the smaller 4-4-0, several years ago.  It appeared to be a perfect fit.  These boards are now available from the parts store.

The underframe, end beams and trucks are clearly identical to those on The long caboose.  In fact, the end beams have holes in them that were originally used to seat the ladders on the caboose.  All of the upper super structure appears to be brand new.  Overall, it is an interesting and colorful car!
