fuse keeps blowing
fuse keeps blowing
went out last night... and i took off from a light like normal... and from first to second, my car died... so im rolling and i try restarting it... NOTHING. so i pull over... and come to find out its my ignition fuse under my hood.... (30A) my horn, headlights, foglights, and pwr locks work, my pwr windows, radio, and thermasta doesnt. so my friend and i run to a 24 hour Auto Zone and get a 30A and a 40A fuse.... $8 bux... it was really expensive... well i end up blowing the 30A and the 40A..... by now im getting kinda pissed.... so we shove a screwdriver in there, and the car still work turn over, the starter wont ever turn over. so if anyone has any ideas... please help me. thx.
you have a major short somewhere. do you have a wiring diagram? if so unplug every part you can get to on the circuit. put a fuse in. if it dont blow start pluging stuff in till it blows. that will isolate it to the problem circuit. then its just a matter of tracing only that circuit for the problem.

*itch post what car you have next time, I had to check your previous posts to confirm my suspissions.. Luckilly you only have 9, and I was correct in my assesment in that it is the s14b 
Do me a favor and check the harness after the injectors where it runs under the breather tube, and towards the front of the head...
Almost spot on positive its resting on the bolt in the head and has eaten through the harness and nailed blk/r.... or the primary ignition wire... Youll see arc marks on the bolt and the harness will be worn through...
I learned the hard way and tested EVERYTHING before finding it, and had to have my car towed for the first and only time the night before...
If you are uncomfortable with electrical email me as you are local and I am free tommorow...
Also post if I am correct, and Ill tell you how to fix it 100%...
Funny thing is mine did the same at about the same miles give or take 1 - 5 thousand...
Edit: DONT EVER JUMP A FUSE WITH SOMETHING NONFUSABLE AGAIN.... HOPEFULLY YOU DIDNT **** ANYTHING UP TOO MUCH BY DOING THAT......
oh yeah and iirc after I did this I found out there was a tsb (from another didnt actually see it though I could check) out for this problem as well.

screwdriver went in there cuz my windows were down... (electric windows) and all the fuses work execpt the ignition fuse. that one keeps blowing. we were out of ideas and i was about 20 miles from home. some wires must be touching... just i got the car about a week ago... and i have never owned a nissan before... so this is all new to me.... ill shot you an email.

Come on nistech.... I said he had an S14b....
Anyway it was a short in the harness, where I said, and with the blk/r primary ignition wire... Went out there this morning and got it taken care of... I fixed the wire, then wrapped the harness, then split loomed and wrapped it then wrapped it in 2 places (where it touches 2 bolts on the head) with a split peice of 5/8" heater hose, then wrapped it again with self amalgamating rubber tape....
I did it up the same way I did mine, and um well... Itll never short there again...
Like I said, I'm pretty sure there was a TSB on this...

I heard from another owner who went to nissan to have it checked... He checked back to see my reply afterwards, said I was right, and also the way I suggested he fix it was how they did it at the dealership... So mabey there wasnt a tsb on it...
This particular situation is rather easy to spot for me now though as I had to go through it first hand. I only found the short after testing every single thing directly related to the ignition, with my fsm and multimeter (a great tool but oh what I would give for a consult II )... Upside was I knew everything ingition related was good, downside though was it took many hours of testing to find that silly short, which requires a 10 minute fix.
I got to help a fellow member out I didnt know so it was good...
You may get a kick out of this, a problem I am going to fix for him... The previous owner went to a single electric fan... He wired in a new 4 wire relay and fuse to the fan (a spaghetti install behind the battery). Guess what he used for the trigger to the relay? One of the 2 power wires in the harness that go to the stock cooling fan, which has its own relay and 30amp fusable hehe So when the ac comes on or it gets hot it goes through the stock relay / circuit, then triggers the new relay off of this. He could have cut the male connector off (fan side) and soldered to the low speed side of the circuit to get the same effect with no extra mess....
I hate seeing burned out 240's...
