Rookie Mike, If everything quit, then the main fuse or breaker in the mail power feed to the fuse panel is blown (fuse) or open (circuit breaker). Next guess would be either the positive or negative side of the main power feed has a loose, disconnected or corroded connection. Start at the battery and follow the power. A voltmeter is your friend in any troubleshooting. If only one or two items quit, then the problem is between the fuse panel and the device(s) that aren't working. And by the way, you should not jump on someone elses posts. Start your own post.
