I've been postponing wiring the frogs of the switches so far, but I thought today would be a good time to give it a try.
What's the frog?
I found this video on Youtube quite helpful:
Wiring the frog!
The Tortoise manual provides minimal information and the same goes for the Peco pamphlet. I'm using two of my previous posts: here and here.
I connect the frog (green wire) to terminal #4 or #5 of the Tortoise motor, then I connect the main feeders (red and black wires) into terminals #2 & #3 or #6 & #7:
Then, I can test with a multimeter:
The switch is not turned, the frog and the bottom rail have the correct polarities |
The switch is now turned, so those two same rails have the same polarity |
The switch is turned, the frog and the top rail have the correct polarities |
How about a double slip?
The same principle applies to a double slip switch. Two things to note however:
- The frog seems to be that tiny element on each side
- Each frog relates to the opposite switch motor
Running through a frog-wired switch!
As usual, we'll conclude with a short video of an engine running through a switch with its frog wired:
