When replacing an old battery the 80 amp fusible link for the battery was blown. The case for the link can house 2 fuses one for the battery (Top) and one for diesel (bottom). I only have the fuse for the battery since my truck isn't diesel. There are 4 wire sets two are white and connect to the left side and 2 red and blue wires on the right side. One is a single wire the other is a double wire. What I need to know is which set is bolted into the fuse itself and which is bolted into the empty fuse slot? I didn't think to look at the location of the red and blue wires coming into the right side of the link when removing the wires to replace the fuse. I have tried both locations and continue to blow the fuse. At $12.00 each it is getting very expensive.

Either the battery got hooked up backwards and there is a blown fuse or a burned fusible link, or you did not connect all the wires to the positive battery terminal (there should be three).
I'm sure that if it got hooked up backwards, you will know about it (there would have been lots of sparking going on).
If this is the case, check fuse #24 in the Power Distribution Center (20 Amp) in the engine compartment. If this fuse is good, it should have power on BOTH sides of the fuse when it is checked with a test lamp. If there is no power on either side, then the fusible link either did not get connected to the battery or is got fried. The fusible link itself is ORANGE and is a 20-Gauge fusible link.
It all depends on how lucky you are today. Connecting the battery backwards can destroy some high-dollar stuff. If you are really lucky, you will only have a blown fuse (or fuses). Check both of your main fuse blocks on the left side of the engine compartment,
One of the boxes is called the "Fusible Link" box and the other is called the "Engine Compartment Junction Block" (J/B) (See picture below).
Your main circuits are protected by the 40 Amp and 80 Amp fusible links in the Fusible Link box and the 120 Amp Alternator Fuse in the Junction Block. You will most likely find one or more of these fuses/fusible links blown.
Look for a blown fuse,or fusible links to be burned out,these fusible links will bolt onto the starter with the positive cable,I do not know what year it is,but if it is a newer model,there is a fuse on the rail,on passengers side,near the radiator,it will be a flat fuse with two mounting bolts on each side of it,150 amp,or 200 amp,or lower,disconnect the battery before replacing it.
this is a little vague on what the issue actually is.. All vehicle batteries are grounded to the body on the negative side so this does not explain anything.
We need to know just what the issue is, like blowing fuses or something not working..
If you mean that the battery positive was grounded and now you have lost power, look next to or mounted on the battery for a bank of large fuses or wire links called fusible links. If you have accidently shorted a positive circuit to ground the chances are that you have blown one of these fusible links. They are easily replaced. The same goes for the vehicle circuit fuses which should be checked electrically with a test probe and any found to be blown should be replaced with a fuse OF THE SAME VALUE. NEVER replace a fuse with a higher value, this presents a serious risk of fire !!!
check for blown fuses in fuse boxes under dash on left & under hood.check for a blown 'fusible link' a wire leading from battery + terminal to the electrical box near the battery.a fusible link is a wire designed to 'melt' in case of a short.outside of link will appear blistered,and a new one needs to be soldered in it's place.
