12V DC Question
I have a light switch that has 2 prongs on the backside, and both have an orange wire to it. How do I determine which is the Hot side and which is the switched side? Or is one Hot and the other Grou...

The wire is probably the hot side and the switch only breaks the electrical path when open. The light is most likely grounded at the fixture. All 12VDC ground lines on my coach are white and run in a daisy chain to common ground points. To check which side is live, use a volt meter or 12volt test light from ground to each side. The one that reads 12 volts will be the battery voltage side.
