Ok so i have a 92 civic Si with a JDM d15b. With that said i have a wiring problem. Here we go..

So one night after work i went to start my car to let it warm up. I turned my parking lights on like always. Right when i turned my headlights on, they got really bright and blew out. So i thought it was just the blubs, went and bought new Silver stars and the same thing happened when i put them in. Now my alternator was bad to begin with and never got around the changing it, well this time my ground wire was really loose and sparks flew everywhere when i tried to start it. Turned the car off when that started happening. Now every time i turn the key to Acc. it blows the ASG and the SRS fuse. I dont know what to look for or do cause i know nothing about wiring.

If anyone has ANY input, please feel free to PM me or leave a little something on here.

 

check the alt. fuse under the dash.

i had to replace my driver side fuse box, b/c i was throwing a ELD code.

i replaced the fuse box, and 1 o2 sensor, and the code never appeared again.

check the codes if any, check the fuse box under the hood for the hazard fuse, and then under the dash for the ALTernator fuse.


just have patience boo!!!!

 

I replaced the whole underdash fuse box and still the same problem. I cant check the codes cause once i turn on the Acc. the check engine light goes off when the other lights go off.

 

check wiring for short to ground

 

Does it sound like JUST a ground? Or maybe 2 wires burned together or what?

 

Sounds like a dead short to ground on a fairly large wire. Check the wires running to the positive battery terminal, the alternator, any other larger wires, to make sure the insulation is fully intact, and it isn't shorting itself to ground. Those fuses you're blowing aren't small, and it takes a lot of current to cause that problem. You may also want to have the battery tested while you're at it. Usually, a short is very bad for a battery.

 

Well i bought a new battery and terminals when it shorted out. So i know those are good. Ill check the grounds tomorrow when i get off work. The only thing is, i cant really get to it because its under the intake manifold. But ill do my best! Thanks!

 

Grounds hitting the body won't cause a problem.

A "hot" wire, or positive terminal wire, making contact with a ground, or the body of the vehicle, engine block, head, transmission, other grounded part, etc. will.

I'd look for signs of arcing, melted insulation, etc., on a 12V primary wire first. Usually, a smaller wire would have the potential to burn through before a 40A fuse.....and would be why most of those are covered with a 20A or smaller fuse. The fact it took out many of the primary fuses, leads me to believe it could be the positive terminal battery cable, or starter feed shorted to ground. That's a good place to start.

Also, make sure the battery terminals aren't hitting the hood, or something of that nature. Same difference!

 

Also, check the 12V feed to the headlamps. (The actual headlamp wiring.) Given that trying the headlights initially caused the problem, there's a chance it could be those wires as well.

Where in NN are you, BTW?

 

I happen to be in the Denbeigh area....
