The fuses I see in the circuit for the radio is a 7.5 Amp fuse marked radio and a 10 Amp fuse marked dome that protect the stereo.If when you turn on the ignition and nothing happens, no dash lights ect....
Check the 3 main fuses up at the battery, the main fuse links protect everything, a set of a 100A, a 30A and a 40 Amp main fuses.
