Some of the circuits you listed, may have more than one voltage source. One voltage source they all have in common is the ctsy fuse 20 amp. Not only check the fuse, check the circuit where the fuse plugs in, that circuit should be hot all the time. Usually the fuse has a bare spot on top for each leg of the fuse. You can use a testlite there, without pulling the fuse, or you can pull the fuse to check the circuit, doesn't matter.
