Electrical Gremlins

Wiring and Electronics, two things that have never been my strong suit, despite taking Electronics/Computer Tech classes all the way through High School, but the mid 1990’s were a while ago now!

With the layout progressing, wiring and getting ready to have the DCC system set up have been getting closer to top of mind, and with them, the requisite search for electrical shorts, despite about as simple a wiring scheme on the layout as you could have. Red and black wires. Connect the red to the track closest to the front edge, and black to the back. So simple, even a caveman could do it according to the car insurance commercials… So of course, I have electrical shorts!!

Uh oh, No Short..Short, the search for the short begins!

I have been trying to be dutiful and test as each wiring drop gets connected to the bus, looking for anything shorting out the layout. It’s mostly gone well, but in the past few days, its become a nightmare.

Highly technical gapping, a piece of paper after the rail joiners are slid away to isolate a section and look for the short. Success eventually…

This time, the short was something stupid, really stupid, two feeder wires that weren’t soldered to the bus, hanging beneath the layout making contact…sigh, that only took an hour of frantic searching and filing gaps on switches and losing my mind over what had happened.

At this point, I was back up and running test trains using my Lokprogrammer for command. As they say, to be continued…

  1. Oh, I can see how that can happen…
