Okay so I have an automatic 1996 Infiniti J30t....I recently installed a stereo in it with the works.
As I was leaving a HS football game It just QUIT on me.and i coasted to the side of the road.
Now.When u try to crank it it does absolutly nothing...Although the interior lights and headlights come on,the windows will not roll up and the warning lights dont show up either.
I tested the battery at autozone and they said it was good.
It dosent even try to turn over.
Tried jumping it off many times and it still does nothing.
Foriegn cars are WEIRD and COMPLICATED..
Please help
I checked most of the fuses but not all of them..Which ones specificlly should i check?
I dont think its the starter or the battery or the altenator...
I have no clue

It does sound like a fuse issue.
You need to check ALL of them, both the inside kickpanel array and the fusebox under the hood.
Dont trust just looking at them.
Get a ohm meter and test all.

Welcome to NICO !!!
and report back after a thorough fuse check.
I'm not a guru on the electrical side but I'm sure someone in the know will chime in soon.

Since you threw in the stereo part, makes me wonder..How did you tap into the battery for amp power? Start with the things you did in the stereo install.

Havent checked the fuses yet.
But I will very soon.
So keep checking in on me.
To instal the system i have.. I ran wire from the radio fuse on the side, to the radio...Then rewired all my front and rear speakers.My amp has an 8 gauge wire running from the positive terminal on the battery.and the ground on it should be somewhere on the trunk..I really should check that because i didnt make the ground,a friend did it.antenna wire from the amp to the cd player.And thats it.
Ohh yea and the 8 gauge wire actually has a fuse of its own..

Oddly enough it ended up being the battery.
We took it to auto electric and they put another battery on it and it started right up..
But we took the battery to autozone and they told us it had an 80% charge..
Autozone dosent know s***.
