Hello All,
After a couple of installs I seem to be somewhat getting the hang of installation pitfalls.
Alas... Today as I was installing a LM-3S into a ScaleTrains GE ES44AC, (the CSX 1776
), I noticed something that had not come up for me before.
The LM-3S documentation shows the following diagram:
9 Pin Connector
Output 3 - (Green)Rail 1 (Red)Motor + (Orange)Common + (Blue)Output 1 (white)Output 2 (Yellow)Motor - (Grey)Rail 2 (Black)Output 4 (Violet)So far. So good.
6 Pin Connector
Output 5 (Green)Output 6 (Violet)Negative (Yellow) Input 1 (White)
Speaker (Brown)Speaker (Brown)Curious as to what would be the purpose on a locomotive for the Negative and the Input?
