I have a 86 efi toyota pickup and it keeps blowing the 80 amp fuse in the engine bay. It blows the fuse after driving the truck for more than 30 mins. Any body know where the wire run to so i can check them?

trace the wire... considering its an 80 amp fuse, it isnt running through some 20 gauge wire.. it is a big wire..... i am thinking you have a bad connection or bad ground because extreme resistance will make it heat and blow over time, otherwise it would blow instantly if there was a direct short
