I’m somewhat new to DCC and decoders, with a very basic electrical backround. I purchased a EMD SW1500 with a paragon 2 decoder installed, and I have been having some troubles with low speeds around some turnouts that have powered frogs and have clean rails. I was intereseted in purchasing a KA4 Keep Alive Cap. and would like to install it however I’m not sure where to install it. Not sure how to upload a picture on here, I’m new, but if anyone knows what the paragon 2 decoder looks like it would be helpful to know where to put the wires for the Cap.
OK, I’m gonna try to revitalize this topic. I contacted broadway limited and this is what they stated. They did give me a brief description of some of the pins which was for a different model but I could follow along and make an educated guess as to which pin was what.
Broadway: “Our Paragon2 decoders come equipped with a capacitor to keep the engine
going during a very brief interruption in power, is the engine having a
problem while going over a frog or a switch?
The reason I ask is because you may not need to install a Keep Alive if
there is something going on with that engine like a pickup issue - if
that is the case we can definitely assist you.
We do not support upgrades/modifications here in the service bay, and we
do not have any experience with installing a Keep Alive on our decoders.
Because of this, I do not know where or how you would hook up the wires
for something like that.
Please be advised that any malfunction of the decoder due to
installation of a Keep Alive is not covered under warranty.
Pin outs can vary based on what is programmed into the decoder.
