In response to a forum members e-mail about controlling his bascule bridge I looked into the instruction packet that came with my Lionel 213 bridge to see if the controller that came with the bridge would work for his bridge.
Inside the instruction plastic bag was instructions and a diagram showing how to connect some type of PCB and speaker to the bridge up/common/bridge down terminals. I bought this bridge from a forum member so maybe he put that sheet into the bag. It shows power connections with 1N4001 diodes between the connections for up/down.
I’d like to scan it a post the image but don’t know how to do that. I could e-mail it to someone if you think you can identify it.
Any ideas.
