A silly? electrical question

[Peter S. in Iowa]

Hi all,

Still settling in with my new-to-me fiver. Couple of electrical questions:

If I want to run a new 12V circuit (there are several empty fuse locations in the panel) where does the white (neg/grd) wire connect to? It appears from the back of the panel that only the positive (black) connects at the fuse location. Any help would be appreciated.

Does anyone know an easy way to access the circuit breaker/fuse panel? I have a standard 2010 fiver and the panel sits under a cabinet on the street side just in front of the dinette. When I unscrewed it, I can only get it to come out an inch or so. It is held in place by wires. Next to the panel is another cabinet and there is a divider panel held by screws. That divider panel screws into the shelf which serves as the bottom of the cabinet directly above the electrical panel. That bottom shelf has carpet glued to it so I haven't investigated yet if I can easily remove that shelf, which would be the easiest access to the panel (from directly above it). If anyone has experience here, I would be very grateful for any input.

Finally, to check 12 V wire voltage with a multimeter, is it a simple matter of attaching the probes to the positive (black) and neg/grd (white) wires and getting a reading of something around 12 volts?

Thanks all!!!

Scamp has used several different panels. What Brand and model does yours have.

Typically there should be a negative bar, in the panel. All the negatives will terminate there.
