My 0-36 Fastrack switch works, but it fails to send signal to the controller for the green light. The Red light works fine. Changed out the switch and all works well. What would cause the GREEN light not to come on is the question? Problem is IN the switch.

Are you saying that when you swap the turnout with another and using the same remote, the remote's green light comes on when the turnout is in the through position?
If so, and everything else on the turnout and remote controller work correctly, then it could be a faulty Motor Control PCB (I've seen this before). On the RSC Lights switch terminal, there should be either +5VDC or -5VDC (relative to the GND terminal) depending on the turnout position. The Bicolor LEDs in the Remote change color, depending upon the polarity sent from the turnout's Motor PCB.
There are have been 3 different O36 FT variations (3 each Left and Right with remotes) Which model number is yours?
Also, did you purchase this from an Authorized Lionel Dealer and if so when? If it's still within the Dealer's exchange time frame, that may be the easiest thing to do. If not, the PCB is available, but there are some caveats to replacing it, depending on the model #.
"Are you saying that when you swap the turnout with another and using the same remote, the remote's green light comes on when the turnout is in the through position?"
Yes. Same Controller, but different switch and all works fine.
6-12046 is my number on the switches. Just odd. it worked before I did some track work and now green light does not come on.
Could it anything to do with the power going in or if like you say...it is a motor connection problem, then I keep it for parts.
Thx for response!

It's unlikely a problem with the motor, it's more likely a problem on the Circuit Board. The board fault could have been caused by a voltage spike, like what often occurs during a derailment. (TVS diodes can help mitigate this issue and more info about them can be found in numerous topics on this forum)
The original board for the 6-12046 is no longer available, but there is an alternate replacement, which will work with a few minor modifications which don't require soldering.
Here is a link to the Part # 691TRC4A01 ($23 + shipping) if you're interested:
