All of the electrical circuits on my old Mopars seem to work so much better now that I am using silver conductive grease on the fuses and on the spade connectors that attach to the fuse box. Also, the fuse box power feed buss bar should be soldered to the power feed spade connectors (leave the rivets in place and just solder on each side of them). Basically, solder all the riveted connections in the fuse box using rosin core (electronic-type) solder.
