Fuse #13 Blows
I have a 1984 20th Ann Mustang 5.0. And the dash lights don't work. I have found that fuse #13 blows every time I pull the headlight dimmer switch. Either with a 5amp 10amp or 15amp. When I put a 30 amp in.... The lights do show up but then after like 5 seconds fuse #4 will blow(20amp). Both #4 and #13 power the instrument cluster. What would cause this to happen. And I do have an aftermarket radio in if that matters. Other than that everything is stock.

Blowing fuses is usually a result of either electrical shorts, or excessive voltage/current in the system. That's what the fuse is for after all, to prevent the system from overheating and starting an electrical fire.
