    Default Kato terminal track fried

    I hadn't run anything for a while, I have two unitrack loops that are powered separately. I ran engines on both loops and one of the loops stopped working. After investigation, using the good leads into the dead terminal, I was able to determine that the terminal track that was powering the loop that stopped is now dead. I was running two new atlas engines and using a new MRC Tech 4 260 when it all stopped. I wasn't aware that you could fry a terminal track, I guess there must be something inside that plastic plug in that can "go". Anyone else encounter this kato unitrack terminal track failure or hear of it? Any thoughts to the cause?

    Could be an open, and most likely is, rather than the oft-blamed "short."

    Any scorch marks or smell of burnt material? Still have the receipt or is it within a warranty period?

    I agree with Paul on it may be an open, unless you have evidence of a chard connection. I took one apart for a similar issue (no power) and it must be assemble correctly to work. The inside is made of spring wired type of runs from the connector to the track if that makes sense.

    Take out the screw and have a look inside , its a very very simple system . To simple to be reliable over long term IMHO

    I can't imagine it being a short. It has no moving parts, so what changed? A poor connection seems likely. If it somehow shorted, the end result would be an open. Check for continuity and then crack it open.

    I just took it apart and one side where the spring touches the plastic is a little scuffed, it appears something happened to discolour/scratch it in a minor way. I'll hit the Hobby Store and pick up a new one, maybe two just to be sure!

    That MRC Tech 4 260 is putting out 12v at 60% throttle (mine does).
    Were you running full throttle when the fault happened?
    I agree with the others, something cooked and is now is gapped, and causing an open.

    I had this happen on the one terminal strip that I have on my layout, that was included in one of the track kits that I originally started from. All the other feeders I custom-made myself by drilling small holes in the 'ballast' next to the outside of the track and soldering wire to the outside of the rails. I replaced the fried terminal section and have had no problems since. Perhaps it's just not beefy enough. I'd suggest making your own as I did. Some folks have done it at the joiners...I just pick a spot with a short section and have at it.
