I have an AC and DC distribution panel installed in my cargo trailer. And I think I have an issue with my DC side of the panel.
This is my first electrical work of any sort and thought it was going well until I checked voltage at the end of one of my circuits. I had 12v. But no fuses in the distribution panel. I was expecting nothing. I did wire up a small LED light and there was a faint amount of light coming from it. If I put in the fuse, LED lights up with the expected brightness.
Are my expectations about having no voltage incorrect?
If they aren't incorrect, what are some troubleshooting steps I should start with?
The specific panel I am using is a
Arterra WF-8930/50NPB Black RV Generator and Component (Distribution Center 30 Or 50 Amp Ac Service - 15 Dc Circuits -) and the manual is here.
