If you replaced the fuseable link cuz it was melted that tell me that you have what is known as a Dead Short...A Hot Lead (Positive Wire) is shorting out somewhere in your car,that is why the fuseable link is there,to keep your entire wiring system from catching fire...Its a BIG FUSE!! go get a Multitester and start at the Head lights and work your way thru the engine compartment,under the Dash ,all the way back to the tail lights...focus on HOT wires (Positive)

You Have A Big Fat Short Somewhere!!!!!!!!!!!!!!!!!!!!!!!!!! CHECK FOR BLOWN FUSES!!!!!!!!!!!! Are you popping a fuse on a regular basis? If so Thats the circut I would start with!
