Aftermarket radio & dome lights have no power

[E21newb]

Just got back from vacation and went to start my car. Everything started fine but my radio and dome lights did not power on at all. I checked the fuses and all seemed fine. Also checked the wiring behind the radio and that also looked good. Have no clue what it could be. Before I went on vacation it worked. Has anyone has this problem?

Do yourself a favor, dont test power with your eyeballs.

For simple circuits like this, use a test light. If you don't have one, pop in any Walmart or auto parts store and grab one.

Once you actually test for power at the fuse, report your findings
