In reading the others responses, you have cleaned up the grounds so that can be ruled out as being the problem. A 30 Amp fuse should handle every situation on a Model A with some margin. If you had all the lights on( Not high current Halogen headlights) and blowing the horn and electrical wipers on still should not be using 30 Amps of Current. You have an intermittent short somewhere. Do you have a new wiring harness? Do you have one of the later terminal boxes? Are you using the original style head light conduits which plug in?
