    I have a question about my fuse box. It appears that I'm missing a relay or something. The top square shaped slot is empty but it looks like there are terminals in it for something to be there. As you can see the description given is FL ALT 100A. So my issue, besides what i have already stated, is that my truck starts and drives, but NONE of the electrical works. Radio, headlights, tail lights, dome light, dash; nothing. A few months ago everything did work with the exception of one headlight. it was really dim compared to the other one. I tested a new bulb but it was the same so I figured it was a ground wire loose but I never got around to really working on it. This morning I had the alternator tested and it failed so I know that will fix at least some of it. So if you guys could give me some insight it would really help. I will be happy to answer any more questions if you need more info. ThanksIMG_0953.jpg IMG_0952.jpg

    That isn't a relay. It is a 100 amp fuse. They bolt in to the fuse box. Kind of a pita to replace. I wouldnt replace your alternator yet. Chances are it's not bad... you have no fuse lol

    I've owned this truck for about 5 years and I have very rarely had to open the hood to check anything. Less on the fuse box. I honestly have no idea how long that thing has been gone. I've never had any issues out of the truck until recently. So by replacing the fuse do you think that will solve my electrical issues? Or at least the majority of them?

    I zoomed in in your picture.maybe u could look closer and take a pic too... The fuse is there, the steel strap is there that goes into each terminal. But the casing is gone? Can u tell if the fuse is blown?

    If you look really closely you can see that its broken off on the right side but its still close enough it probably made contact to power everything at one point. I'm going to go ahead and replace, it. Thank you, I saw it but it just didnt register with me that somethiing was wrong. Hopefully that will put an end to my, electrical woes. Do you think that could have anything to do with my, dim head light? I had a head light issue before this but never, got around to chasing down the ground wire to check it. The passenger side was fine just the drivers side.

    That fuse appears to be broken (open) from that picture. I'm thinking at some point someone tried to pry it out not knowing it's not a pull out. Probably why the plastic case is long gone and fuse is split.

    Some Mods :) See build thread for details
    Definitely a start to replace it. May not fix all issues but see what it does fix and go from there.

    If it's the proper amp you should be good to go.

    Looks right. Make sure the truck is warm... that plastic gets brittle when it's cold. Be patient and have about 4 small flat head screw drivers ready in hand. You'll See What I mean:)

    Well apparently this will be my first build thread ever. My engine compartment fuse box is in pretty bad shape, a few years ago someone broke into the truck and did something to the fuse box. Aside from busting the box up pretty bad i didn't think anything of it. All the mounts are broke even the box itself is broke. It's all held together by the fuse box cover. So anyway, it's a little difficult to see but in the top photo you can see the cable on one side and on the other there is a small hex head bolt. I checked it out online and most write ups say it is a through bolt but on my truck it was 2 small bolts on either side, one with the cable, one without. I had to completely remove them. but the interesting thing is that I had to drill through the fuse box to even have access to it. (I have no clue how a dealer or shop would do this, I tried tugging on it and even removed the back with no luck.) I used a 1/4 inch drive deep socket for both sides. One was 5/16 the other was 10mm. Oh, the hole through the box was 1/2 inch to allow for the socket. Once I had both small screws out the tabs that were left in there just pulled right out. After i put the new fuse in, it didn't need to have the screw pass through, I re attached the cable with the screw with my new access hole and put the screw back in the other side. And the rest is just putting everything back together. IMG_0960.jpg IMG_0966.jpg image1.jpg

    Thank you guys a lot. And a special thanks to LOTSOFTOYS for noticing what i just breezed over at glancing at the box. So i will answer any questions if anyone has any. And I do understand that not everyone is willing to drill holes in their fuse box, but hopefully this can help someone. Now I'm going to start a couple more threads. I still have to find the ground wire for my drivers side head light and my oil pressure gauge always reads zero even after i replaced it.

    Damn. What a pita.
    Good that you went with Littlefuse. There are similar PAL rated knock offs for $3 bucks or so that are just plain crap. Littlefuse or Buss are the only brand fuses to use.
