I think he wanted you to pull out those "dead" fuses and check the voltage at the metal fuse holders where the fuses plug in and see if those metal holders were getting 12v. If they are, then the fuses must be blown since the fuses aren't lighting up. Pretty sure that's what he was targeting.
alright ill check now

The 3 that lit up have 11.95V on both sides and the other 5 read no V on both sides. Does this mean the fuses are bad or they arent even getting any power? The fuses that work are the bottom 3 on the left side.
