Atlas Dwarf Signals
Arnie wants help from readers and asks:
“I have followed the directions included with the Atlas dwarf signal included with the device. I am using Atlas switches. I can not get the light to change. It stays either red or green depending on how I connect the 2 leads from the signal to the switch. I can make them work properly eliminating the circuit board and using a relay, but I would like to use the circuit board. I have switched circuit boards with the same result. Any suggestions from anyone?”
