The headlight wiring and radio wiring is getting in contact and causing the short.Both the grounds needs to be checked.Because when headlight is off,the radio work's fine.As soon as the headlights are turned on,the radio goes in scan mode.Its clear indication of radio and headlight wiring issue.The wiring's are getting in contact with ant metal surface or both the radio and headlight wire are coming in contact,where they should not.I suggest you to check the headlight and radio wiring diagrams for your lincoln town car.Here is the direct link.Click the link below :---Check out all the 3 links one by one.Radio wiring diagram for 1997 LincolnTown Car?http://technoanswers.blogspot.in/2012/02/radio-wiring-diagram-for-1997-lincoln.html

there is no headlight fuse, the headlight switch contains a circuit breaker that trips out when a short takes places and then resets when the short goes away.

You have a bare wire short some where. Look around the alternator and starter. Also look and smell for smoke or burn rubber smell.

Hope you can read it, the load side of relay gets voltage from fusible link. The load side of relay is that line with arrowhead, showing open switch on left side of relay in diagram.

Here ya go!

Had same prob.Put volt meter on amps and read amp draw on battery as you pull fuses out.mine was ingnition switch was not turning off when key out.

Try this site download the ford service manual and make a cd they have instruction how to do it. Should have all your wiring diagrams and more.
