INST Fuse blowing

Put our cluster back in after wiper refurb and cluster refurb. All other cluster lights work. Connected the battery turned on the running lights and checked for instrument lights, nada. Found the fuse blown. Turned off lights and replace the fuse, blew again. Got handfuls of fuses so tried another one and it worked for a while figured it was cheap Chinese fuses. Try it again later to show off our handiwork to someone and it blew again. What do y'all think? What else could be loading up the orange wires? Or could it be from the headlight (tan wire) switch side? Where else do those orange wires go? Oh yeah, 1973 Scamp. Thanks for the help
