No idea on the 1st question but to answer the 2nd question
you can use a volt meter and or a test light
check the fuses by checking if you have power on one side you should have power at the other side if not than the fuse is bad if to use a test light clip the one side of the tester to a good ground and touch the fuse with the other end if lights up on one side it should do so on the other if not fuse is bad
