fusable link again

[z10kl]

My 70 does not have the link between battery and junction block. In some of the wiring diagrams it looks like the wire from the bat to block is 18 gage and some look like it says 16 gage. According to this post below I found it is 10 gage. So would I be correct that the wire that comes on the bat cable is 10 gage and the link I would buy should be 16 gage? Does the link connect directly to the block or is there another wire between them?


Quote from the 1971 Chevroklet Truck Chassis Service Manual. " Fusible links in the Chevrolet wiring are four gauge sizes smaller than the cable it is designed to protect". The engine compartment wiring is illustrated as a 10 gauge red wire coming from ythe battery + to a junction block. A fusible link of 16 gauge wire attaches to the junction block and red 12 guage wire then to the various circuits. If you desire to construct your own link; use a short piece ( 1" or so) of solid ( not stranded!) wire attached to the junction. Slide a piece of heat shrink tubing down the 12 gauge wire and then solder the 16 gauge to the 12 guage. When solder joint has cooled; slide the heat shrink tubeing over the juntion of the 16 & 12 guage wires. .........
