I have no problem finding the 5, 7.5, 10, 15, 20, 25, and 30 amp AGC fuses. However, my gauge lights are dead and there is a tiny little 4 amp fuse that runs those. The socket for it is half the size of the others, I guess about 3/4" or so. What the heck kinda fuse is glass, half the size of AGC, and only 4 watts? You think a Radio Shack would have something like that? Or a hardware store? Local parts stores (AutoZone, NAPA, Advance, and OReilly) were of no help. They only have the long ones.
