As the title says, I need help wiring up a pair of Model Power lighted crossbucks to run with a Circuitron DT-2 and FL-2. Where I am having the confusion is which of the three wires is the common. (This would be the OUT wire on the diagram for the FL-2 instruction sheet.) There are two red wires and one black per light. As usual any assistance that can be provided would be most welcomed.
The instructions are for LEDs. LEDs are polarity sensitve. The Model Power unit uses bulbs. You could wire the black wire to the common. The red wires to the other terminals. The FL2 is rated for 2 250ma loads. You need to find out the load of the bulbs. They may exceed this. If so, you can damage the FL2.
The way I read the instructions it covers both bulbs and LEDs. I was thinking that black was common, but I wasn't sure. Thank you.
