I was working with my digitrax stuff tonight, and made a small mock layout with my tortoise machines, and my turnouts, etc.... I bought some bi-color LED's in red/green for my faceplate on the front of my layout so I know what direction the turnouts are thrown.
So with this being said..... 1. on my DS64 turnout controllers, what is the voltage going out to the turnout? 2. If it's 12 volts, WHAT watt resistors would I need to bring the voltage down to 2 volt and 2.1 volt. The green lights at 2.1 volts, and the red lights at 2 volts. So I need to reduce the voltage going to the turnout machine from the DS64 voltage to 2.1/2.0 volts.
Is there a formula?
