Does any one know the value of the keep alive capacitor?..............Peter

Pete ask TCS but per my tech notes their KA1 at one time (may still do)  used 6 X 220,000 uf super capacitors at 2.5 volts each, wired in series.

BTW Peter, I pointed you to TCS because Keep Alive is their product.
Current Keeper is a SoundTraxx  product.

Thanks to all. Much appreciated. After looking at the photo, I realize that my decoder actually precedes the B2TS series. I do have the B2TS in one of my Shays. It has the plug-in pins per your picture, that plug into the Bachmann board. The decoder in my older shay is a TCS 312D48, REV AR2. It is hard-wired - no pins to plug in to the Bachmann board. Any help with that would really be appreciated.  Thanks.

Also, I have some 1 farad, 5.5 v capacitors, if that would be an easier solution?

The above link should go to Marcus Ammann's Stay Alive page.  It has lots of info on adding stay alive capacitors to a variety of decoders.
