Another bizarre issue for Storm88000
This is the part I hate about cars. ANYTHING ELECTRICAL. I just did a frikkin' head gasket on a VE but this kinda crap, I have no idea.

OK, so I was driving my B14 and all of the sudden I smelled smoke. All electrical things stopped working, radio, A/C etc. Luckily I was 30 seconds from my house so I shut the car off and pulled into the driveway, and popped the hood. The smoke was coming from this:



Specifically, the 75A battery fuse, was literally was on fire. I smothered it out, but now of course I have no power to anything in the car. Here's what it looks like (center):



So now I have a problem that I'm hoping you guys can help me with. Since the fuse literally melted, it is impossible to remove it to replace with a new one. I've tried pliers, screwdrivers, everything. There are also like 20 wires going into that box too, here are some pics of it:





And the bottom side:



I removed all the fuses from the top, including the regular and Nissan ones, but none of those wires will budge. They are really in there. I also tried pushing from above hoping they would come out, nothing. I tried tracing the entire wire assembly back to some kind of harness that will disconnect but I also found nothing. I'm guessing there isn't one?

I am thinking there are 2 scenarios here:

1) I somehow find a way to remove the battery fuse that blew up and replace with a new one

or

2) I have to get a whole new fuse box from Nissan, and cut the wires and reconnect them to every single piece.

What do you guys think?

It's another dumb stupid thing that could only happen to me. The car was fine and I have no idea why the fuse blew up.

ok first off, theres gotta be a reason that happend, have you done any wiring lately?

that big red wire that goes to the starter looks a bit odd..

im wondering if your alternator voltage regulator went tits up an tried frying your battery, an the fused stopped it and hopefully nothing else was damaged..

or maybe some wire some how grounded out somewhere..

No wiring done. I never mess with wiring, I hate it. I like bolts and moving parts, wiring bugs me. I did however just put in new headlight bulbs, a day before, but I'm not sure if that's related or not. The car has given me (besides 1 broken axle) about 50k trouble free miles besides these little weird things here and there.

I basically need to find out if there's a way to pull those wires out of that fuse box without cutting them, and/or if I need to order a new box from Nissan. The one that burnt up is pretty much like stuck in there. I don't even know the part number and couldn't find it on Courtesy Nissans website for a new box.

FWIW the motor itself has Tomei cams, a cold air intake, OBX header, and G-spec underdrive pulley, and a 2.5" exhaust.

Yep. I was driving and was listening to the radio, and had the A/C on, and both shut off at the same time. I was like "WTF?" Then smoke came into the cabin from the defroster vents by the windshield. Thank the all mighty powerful one or many (he/she) that I was only about 1/2 mile from my home, so I coasted. I'm not gonna lie, when I stopped, I jumped out of the car. I came back, popped the hood, and that the fuse box was smoking. I opened it up and just put a towel on it and it smothered it. Now I have to figure out how to fix it.

Check these fuses and see if you have the right amp fuses in them

Aircon
Alternator

pull out as much as you can on your harness and unwrap it

You need to find the cause of that fuse failing before you try putting in another one and rolling down the street. That thing didn't blow for no reason. It could easily be the new headlights.

To get it out, try freezing the thing with a "can-of-air" held upside-down while spraying. If the rest of the housing is warm it should shrink enough to be removed. If not, keep trying it over and over. Heat the whole assembly then freeze just the fuse. If that doesn't work, you can probably crumble the plastic while it is frozen if you want.

Unhook that battery before you attempt to do anything further.

Is this your 97 se-r?
It looks like that 75a feeds the alternator and 4 of the fuses.
Maybe the alt or the big power feed to the alt is shorted.
