Duster fusible link wiring problem
Random thoughts from the old ****, "how to find" a short:
WITH (and MAKE SURE) that EVERYTHING is "off", the key, the dome light, the trunk/ underhood, glove box lamp, the tail lights
IF YOU GET a spark and "sizzling" you have something powered on OR A DRAW that should not be, OR A SHORT
IN ORDER TO PROTECT against blowing further fuses, fuse links, or burned wiring while you find it, DO THIS
Remove the batter ground wire. INSERT a heavy test lamp such as a turn/ stop lamp in series with the battery ground, in other words
from battery post...........to test lamp..........from test lamp..........to ground cable.
NOW IF YOU have a heavy draw or short, the only thing that will happen is that the test lamp will light and it will limit current so that nothing burns up!!!
First thing I'd try is remove the fuses one at a time. RECHECK that everything is off, and then unhook the big black charge wire from the alternator
If none of this causes the test lamp to go dark, then you likely have a short, "wiggle" all your wiring see if it flutters/ flickers/ goes away.
LOOK and SMELL for melted/ damaged/ bare/ pinched wires, melted plastic wrapping/ insulation.
If that doesn't work, you in for further surgery
