no power to dash, windows, locks, etc HELP

[devonkyle77]

so i have all but completed my s14 sr swap and i went to turn the key to the on position to check and see if lights, windows, locks, etc work and they dont.

when i turn the key back off i hear a PSSSSSSSSSSSSSSSSSS noise from the gas tank area, so i assume its pressure being released or the fuel pump. so i would assume thats getting power?
the battery is brand new, i cant figure this out, ughhhhhhhhhhh

please help guys, and as always, thanks in advance.

Check the main chassis fuse under the hood...

same shit happened to me!
its the fusible link...yepp
umm 18 bucks at nissan or you can get it a a junk yard wayy cheaper

[renegade_ewok]

Check all relays/fuses - something probably popped.

Whenever I would play with wiring I ended up popping something out of stupidity (ignition fuse always got me...)

[devonkyle77]

sure enough, it was the 100A FL.
the only one that doesnt have a tab to push to pull it out. how the hell do i get this thing out?

Unbolt it, there's an M6 bolt on either side of the box inside. You can buy new fusible links that are slotted so you just have to loosen the bolts instead of removing them.

no WTF? :tweak:
i pulled mine out with my hands...hmm weird
pull harder..haha

[devonkyle77]

i got it out, what a bitch that was. now if only nissan dealership parts department was open on sunday, ugh

[[email protected]]

you say you have a 100a fuse?
mine came with a 75a fuse...and that was $18 at nissan
im pretty sure you can start your car right?

S13s have a 75A main, for S14s it's 100A. Different car kid, pay attention.

[fliprayzin240sx]

Haha, Russ beat me to it. Anyways Devon, just in case it pops again, that usually means your alternator is fried or your wiring is fubar'd.

True. Check for correct alternator connections, like the plastic insulator being in place on the charge lead and the charge lead/ground lead not being mixed up. Seems someone does one of those two things once a day on here.

[devonkyle77]

everything looks legit, but sure enough, it popped again as soon as i put the negative terminal back on the battery.
i swear i am running out of patience with this car.

[NemeGuero]

You're overdrawing somewhere, meaning you have a bad connection. Bust out a multimeter and the FSM and check resistances across terminals.

Its probably easier then that but I don't have much experience with it. Just be systematic in how you test.

Or you could just unplug things one at a time and keep replacing the fuse till it doesn't pop anymore. Once it stops blowing you've found what is wired improperly..

except you might run through a few fuses.

[devonkyle77]

that sounds like a lot of fuses.

[projectRDM]

Disconnect the alternator lead and try again.

[devonkyle77]

i took some pics, not sure if this shows you anything

[Deftec]

put the 3rd to last pic wire on a better ground.

[devonkyle77]

the ground for the maf?
you really think thats the issue?

[fliprayzin240sx]

I cant see pix but i'd try what russ said first. Take the alternator out of the loop since thats more than likely whats causing it to pop. Either the ground on it is fucked up or the alternator is just shorted out. Nothing on your system should be able to pop that fuse but the alternator.

[projectRDM]

True. Anything else will just blow the smaller 75A, or lesser. Do this though before you go any further, unplug the ECU. It's highly unlikely the short will go through anything but you don't want to risk the ECU.

Disconnect the lead on the alternator, either on the charging stud or in the fusebox, it's the lead that bolts to the stud right beside the 100A fuse. Try another fuse, if it does not blow that's the culprit, the charging lead itself or the alternator.

The MAF ground has nothing to do with your problem.

[devonkyle77]

ok russ i think i follow
http://i84.photobucket.com/albums/k4/devonkyle77/DSC00738.jpg

exactly what u said would happen, correct?

[projectRDM]

Bingo. Problem is either the charging lead is grounded to the case of the alternator or the alternator is bad.

[devonkyle77]

ok great. so obviously i check the charging lead first.
problem is, i dont even know what the hell a charging lead is, what it looks like, or what to do with it.

i suck.

[NemeGuero]

Trace that wiring. Make sure its only connecting in the 2 places it should be. Make sure your alternator has a proper ground wire on it.

DONE.

[projectRDM]

ok great. so obviously i check the charging lead first.

You piss ass fuck. The wire that bolted to that stud goes straight to the stud on the alternator. That's the charging lead. Dammit you making me post when I'm drunk.

[zugoi]

Its ok Rdm i post drunk all the time. Its just your more right then me about 100% of the time. For now.

[Tearlessj]

I dont know if this is your problem, but it solved my issue. The big wire that goes to the alternator with the red cap on it should not be touching the alternator housing. There should be a piece of plastic in between, mine broke off during the swap and I figured it out after 3 fuses.

[devonkyle77]

the wire that bolted to that stud looks like it just goes to the negative terminal though...

[projectRDM]

Well shit man, think about what you just said. A wire coming off the positive battery lead, fused at 100A, is going to the negative terminal of the battery. How would that NOT blow?

That lead, the charging lead, the one bolted to the fusebox stud, goes directly to the plastic insulated stud on the alternator. It does not go to ground. There's a ground lead also on the alternator, it bolts behind the fusebox on the shock tower and comes off the alternator case, on the backside of it. If you have those reversed like I suggested earlier you're sending the entire 100A of current directly to ground.

[devonkyle77]

i am posting pics for u in a second russ.

[devonkyle77]

here you go russ

when i said that, i meant the two things circled in magenta in this picture are on the same wire. i am not sure how the hell i could mess that up. there were no other wires i removed from the stud.

That's wrong, plain and simple.

The battery ground terminal bolts to the battery, then to the chassis anywhere you want, then to the intake manifold/head.

The positive battery terminal leaves the battery and the larger 4ga lead goes straight to the starter. The two smaller 10ga leads go inside to the fusebox, on one leg of the 100A fuse.

The stud in the fusebox goes straight to the alternator. You've got shit all mixed up. I should send you a bag of poo.

[devonkyle77]

ok, i think i follow.




The battery ground terminal bolts to the battery, then to the chassis anywhere you want, then to the intake manifold/head.

so in the last picture, what i had circled in magenta should be bolted to the intake mani.


The positive battery terminal leaves the battery and the larger 4ga lead goes straight to the starter. The two smaller 10ga leads go inside to the fusebox, on one leg of the 100A fuse..

that part is impossible to mess up as i see it, unless the fusebox had been taken apart.



The stud in the fusebox goes straight to the alternator. You've got shit all mixed up. I should send you a bag of poo.

this is where i get lost. i dont see anything available that i could attach to the fusebox.

[zugoi]

How did you mixed those wires up?

[devonkyle77]

ok, wow. it looks like i had the wire for the fusebox on the intake mani, so i had the two backwards. so can u confirm that everything on the alternator side looks legit, so i dont have to waste another one of these damn fuses.

[projectRDM]

The lead coming off the alternator goes straight up to the fusebox stud. As long as you have that done right the ground doesn't matter, just bolt it to the chassis and engine somewhere, there's two lugs on it.

[devonkyle77]

i think this whole fiasco may have ruined my ecu. the car just cranks, no fuel or spark. seems as if everything is good, went to check ecu and it smells funny, kind of like a burnt match.

[chelosx]

its the fusible link!! get it from Nissan for like $20!! needs to be connected to the 100A fuse under the hood!!!
