Atlas #200 Snap Relay for LED Trackside Lamps
John (not the one in the earlier post) has sent in this HO question for readers to hopefully answer. You can comment below.
“I am trying to wire an Atlas #200 snap relay for trackside signal lamps using red and green LED lamps. I have followed the directions in the package but I am not sure were to install the resistors. Also the LED need to have a positive and negative feed. How to you know on the AC side of the power pack which is positive and negative?”
