Troubleshoot operating track | O Gauge Railroading On Line Forum

Tim HOGR Forum Member

I had to lengthen the wire from the fastrack operating track to the controller to be able to mount it by my transformers. Now the uncouple button activates the electromagnet but the unload button does nothing (0V across the extra tracks). Thinking I either switched wires or have a bad joint when I spliced extension wires in. Trying to figure out how it operates so I can troubleshoot it. I am running conventional using track power.

When the unload button is held down, what wires should have conductivity if I put a test lead across connectors (to test my splices)? I would assume the red wire is taking track power back to the controller, the black wire is taking common back to controller. I'm confused on the green and blue. It appears that blue wire is connected to only one of the additional tracks while the green wire is connected to both additional tracks.

Thanks John,

I had seen that thread before but could not find it again, so thanks for the link.

Anyways I assume the Fastrack schematic is the same as UCS and not the 6019. So if I understand correctly, when the unload button is pressed, the wire with red connector (going to center rail) should have continuity to the wire with the blue connector and the wire with the black connector (going to the outside rail) should have continuity to the wire with the green connector.

When the uncouple button is pressed, the wire with the red connector should have continuity to both the wires with green and blue connectors and nothing should have continuity to the wire with the black connector.

I got it all working now. All the info was helpful in tracking down a bad connection where I spliced in a wire to length the cord.

Thanks for the help.
