several do. depending what part of the fuse box is dead the fusebox has two sections one that has power all the time and the other that has power only when the key is on. but fortunately they share a common connection. they both connect to the battery cable down at the starter with what they call "fuse links" fuse links are wire that are designed to burn out under excessive load like a fuse. so first make sure they are not corroded or disconnected and work your way up the fuse links (small wires attached to the battery cable) and test for power about 6 inches up from the starter's battery cable if there is no power there you need to cut and replace the fuse link. DO NOT just splice in a piece of wire. if there is a short in the system you will cause a fire and for that matter it would be a good idea to check for a short before replacing the fuse link. a easy way is to remove the clock fuse if you have one and connect a 12volt testlight to the wire above the fuselink crimp connection (pencil diameter and about a inch long & black) and then to the battery cable.. key off doors closed and everything in the off position. if the light lights brightly you have a short and need to fix it first if the light does not light replace the fuselink and enjoy. hopefully memory serves me right.. there should be 3 fuselinks attached to the batterycable at the starter one is for the alternator the other 2 are for the fusebox.
