Using a CurrentKeeper with a SoundTraxx 21-Pin Decoder
Вставка
- Опубліковано 1 гру 2024
- Have you wondered how to connect a CurrentKeeper or Stay Alive to a 21-Pin decoder? Unfortunately, there is not room on our 21-Pin format decoders (TSU-21PNEM8, BLU-21PNEM8, or ECO-21PNEM) for a CurrentKeeper plug. You can use options like the decoder buddy. But, if you don't have one, you can still use a CurrentKeeper by soldering it directly to the 21-Pin NEM connector in the model. In this video, George will show you how.

Very informative, a zoom-in when soldering would be much better.
I have to agree. A zoom in would help a lot.
Noted!
thanks
I had been researching this.Thanks for confirming the correct way to do it.
Glad to help!
Thanks for sharing. I appreciate you holding up the finished job to the camera so I can see with my poor vision.
Glad to help
I like the variety of videos. The new one with Norman is a cool format too
Thank you!
George Great Tip The Camera View looked perfect. Was able to see all your soldering methods.
Thanks 👍
Just the video that I needed! Thank you
Glad it helped!
Excellent!!!
Glad you like it!
Thank you George, camera looks good
Thanks 👍
Thanks George! Very helpful (I see the patch on you bench😂)
:D
New mount is not bad at all. Slightly out of focus and could be zoomed in a little more for better visibility. However, it was an excellent video as always.
Thank you.
GG👀~,
L@@king good as always brother. Great that you are able to lift the model up for a closer inspection of the work. 👍 You scored another goal here brother!
Thanx Thom...
Thanks 👍
very nice
Thanks
great job George
Thanks
Good job 👍😃😃🚂🇬🇧
Thanks
I believe, this will apply to my Rapido E-8 . AMTRAK 4316 ; correct?
It should as it predates the Mo-Power boards. I have a 4316 and I’m pretty sure I added a capacitor. I know I added one to the PA I own.
This process applies to any of the 21P models out there, so yea, your E-8 should have the same process. I am not aware of anything with the Rapido "MO-Power" boards referred to, so i will defer to others on that. I have not encountered one of those, but in theory, it should work with any 21P decoder that is plugged in.
I hope this helps!

Very fine!!!
Thanks
Yes, Excellant video. And great tip. Os there a mount for other types, of installs?
What do you mean a mount?
Your motherboard had a nice place to solder onto, so I guess if we didn’t have any place to solder onto a daughterboard would be needed.
Which Current Keeper version would fit best in Athearn's newest Tsunami 2 GP50s that just released this summer if 2024?
Our Support Team can help you with this: (970)259-0690 or support@soundtraxx.com. Thank you.
Great information there appreciated the video. What temperature do you recommend your soldering iron to be at? Thanks
In this case, I was using a lead-free solder, so I am up near 680 deg F. Leaded solder can be a little lower, so check the specs of your chosen solder.
I hope this helps!

Helpful George. I have a few Econami decoders that have the micro plug for current keeper partially hidden under the shrink wrap
I also have both third party and home brew current keepers that were successful on the older version with the blue and green/yellow dedicated wires.
This ensured correct polarity for current keepers. Question is therefore is it possible to hard wire to the back of the micro current keeper on the Econami and if so which is the positive?
Also, is the connection a JST 1mm?
I know you sell suitable connections but would like to use the keep Alives I have to hand.
We do sell the plug/harness, so it takes the guesswork out of the equation. The Blue is the V+ and the black is V-. As i show in the video, cut the harness is half and you are set, attach to your home stay alive module, or other brands (if you have that) and plug in. The black is a decoder internal ground and is only accessible through the plug. So, get the 810158 harness and then you can rest assured it will work!
I hope this helps.

I would like to see how to determine using an appropriate motor for a TS 2 1100. I’ve blown out two decoders, one being when programming, ‘short detected’. Decoder was directly connected to programming track.
I had already programmed that decoder and placed it back on PT to adjust CVs. Thanks
Thom, the motor should stall below 1 Amp for use with the 1100s. Voltage differentials can change the current draw. If we venture back to HS Physics, Ohm's Law, V = I x R, voltage equals current times resistance. As voltage goes up, the resistance across the motor is the constant, so the current rises to balance the equation. So, use that as a factor. Contact me for further discussion.

Great video! I’ve added a KA2 from TCS to mine after dual scale sound speakers install back when the PA’s came out. The KA2 was mounted back by the rear light on the chassis, I didn’t need much power just enough for some switches at a club.
I would like to know if the Tsunami 2 could make use of the Rapido Mo-Power capacitors as I have a D10 steam engine I added Tsunami2 into and it doesn’t hold charge. I’m assuming it’s because their capacitor set up is meant for the ESU decoders they use?
Unfortunately, I am not familiar with the Rapido Mo Power cap. Is this something inside their models? If so, in theory, when you use their motherboard, it should stay alive any 21P decoder. i know the esu uses a 3-wire solution, one for charging, one for discharge and a common ground, but our CurrentKeeper only needs 2 wires.
Contact us at support@soundtraxx.com and we can dive deeper into it!
I hope this helps! ~G
@@SoundtraxxDCC they have them attached to the boards, or in the D10’s case in the tender. I’ll try playing around with CV’s to see if they’ll work. I have to do the same for TCS Caps.
