I have a 1993 Camaro Z28. I have this problems with my #8 courtesy fuse and I’m having trouble tracking down the problem. So if I leave the courtesy fuse in my car it will drain the power from the battery. So lately I have just been driving the car without the fuse. Everything else functions fine. A few days ago I decided to put the fuse in and completely disconnect the alternator. I went out in the morning and the car started right up. Does anybody know what could be the cause for this? Everyone I seem to ask just gives me this blank stare like I’m crazy. Please help.

i even took the alternator out and had it tested. It came back good.
