I'm starting work on my very basic 12v system which doesn't currently utilize any fuses. The PO put in a battery to run the water pump, but besides the charger, that's all that's connected to it. My plan is to add a Fantastic fan, an exterior light, an interior light, an inverter, and a charging wire from my 7-way plug.
Despite all of the reading I've done, I'm still a little shaky on how to properly wire a 12v system.
Everyone here has convinced me I need to have fuses on everything. I bought a fuse block like the one below, but now I'm wondering if I bought the wrong kind because it doesn't have a place to feed in a main supply wire the way a circuit panel does. www.oreillyauto.com/site/c/detail/LIT3/350417BP/N1177.oap?ck=Search_N1177_-1_3806&categoryRedirect=N1177&pt=N1177&ppt=C0172
If I can, I'd like to use the fuse block I bought anyway. For each accessory, can I just run a wire from the accessory through the fuse box and then directly to the battery terminals using rings? Or is there a reason why I shouldn't have 7+ sets of rings on my battery terminals?
Should I put the fuse block in an electrical box, or is that unnecessary?
Am I correct in thinking I should run a 10-gauge wire from the battery's negative terminal to a screw in the frame? (Using yet another ring?)
When an accessory has only 1 wire coming out of it (such as is the case for my porch light), I'm pretty sure I should run it to the positive terminal. But what about ground? Does the item have to be directly grounded, via a screw through the skin? Or will that item make use of my battery's main grounding wire?
When an accessory has two wires, one goes to the battery's positive and one goes to the battery's negative terminals, right? Or should one run to a grounding screw? Or will either of those accomplish the same thing?
These feel like very basic questions that I should be able to answer myself by looking at diagrams, but I haven't been able to decipher any because I don't know how to read the symbols. I'm sure there are very clear instructions somewhere, probably even on this board, but I haven't had any success in finding them. So thanks for the help!
