Jaguar xj6 1992 why does the Fuse warning light stay on?

Simple, you have a fuse burnt out. Buy a Haynes book they're 20 bucks. With the car running shut it off with out shutting off the display hit the VCM button and it will help you narrow down which side of the car to look for or if you want check both sides for a burned out fuse. It happens with age...
