Using a DVM in its diode test function, then backed up with performing a low ohms test and checking out the 4 bead diodes that are towards the end, on past your blown fuses, will probably reveal one or more being dead shorted.
OR any of the 4 large black plastic power transistors mounted on the heat sink, may have shorted out.
