Help wiring K-LINE LIONEL 6-22329 Dual Track Signal Bridge

Baaboo: The instructions in the operator's manual seem clear enough. Three clips; power, ground, and insulated rail. What in particular are you having trouble with?

I couldn't get the lights to operate properly. I'm using one accessory track pack; the other I've built myself (since curved track is involved). I'll be trying again. Is a relay (relays) required? Thanks for weighing in on this.

No. You should not need to use a relay.

I do have the instructions that came with the bridge. If a relay(s) aren't needed, I think I can start from scratch in checking the track/wiring. I did make my own isolated/insulated block in one case.  Thanks for replying!

Thanks for the illustration! I'm hoping with some careful rework I can get it going!

Try to power the bridge LEDs without the track. Connect Clip 2 to the U terminal of your transformer. Connect Clip 3 to the A terminal of your transformer. Then the Green LED should light. Then tap the wire from Clip 1 to the U terminal of the transformer and the Red LED should light...Green goes off... When you remove the wire of Clip 1 from tapping it on U, Red goes off, Green goes back on.

If that works, then the bridge is functioning properly. If it doesn't work with connecting Clip 1 to the insulated rail,  the Clip 2 and Clip 3 as connected as stated above to the transformer, and the non insulated rail connected to U on the transformer, and passing a car over the insulated section of track, then there is something wrong with your insulated rail setup.

This is a great summary of how to test it. Thanks! Between it and the other advice, I'm hoping I can resolve the issue.
