Lionel Motherboard Wiring Diagrams

choochoopaulOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

Is there an easy way to find in the supplements Lionel offers, the connections to the motherboards?

I do not think there is a wiring diagram for these motherboards showing which traces on them are connected.

The problem I have is that with all the boards working in a test breadboard, radio, railsounds, and railsounds power supply. When I plug them into the motherboard i am using for a EP-5 setup, they do not work together.

If I power up the track without a TMCC signal, I have control of the AC motor, directional lighting, engine sounds, horn, and bell.

If I power up the track with a TMCC signal present, the engine stays silent, until address it with Eng.# Aux1.

Then I have control of the AC motor, front and rear couplers, directional lighting, engine sounds, but no horn or bell sounds when commanded.

Any help will be welcomed.

Not quite sure what you are asking for, but something like this?

This was found on the Lionel Webpage for the product.

You can also see the Supplement Index East Texas Model Trains has put together:

Thanks for the reply BMORAN4!

I have used this diagram to put together the conversion of this engine.

What I was looking for was the connection between the radio board, and the Rail sounds board. It seems that the sound board is not connected to the serial signal from the radio source.

The pin outs for the radio and sound boards on the motherboard would be helpful.

Thanks again for any help.
