Thank you to those who have responded to my post earlier today! I have been asked to provide additional info for clarity so here goes: I'm running three rail AC. I have MTH Scaletrax track and switches. I have DCS with TIU and AIU. The switch machines are not powered by the track, they are powered through the AIU. Everything functions normally and as intended by MTH. I wish to install NJ International LED switch indicators along the mainline. These indicators have two separate LEDs, one red and one green. Each colored light has a resistor soldered to the power lead and an additional ground lead without a resistor. My desire is to have the green light remain on constantly when the switch is straight, and the red light remain on constantly when the switch is curved. The Scaletrax switch motor is powered only momentarily, then off after moving the rails to prevent coil burn out.
Wiring the lights to the switch motor unfortunately illuminates them only momentarily. If anyone knows of a simple remedy, and hopefully not too costly as I have 20 switches, I would be most appreciative. I am not an electrician, therefore "simple explanation" would be key. Thanks in advance for your help.
