headlights horn won't go off, radio, power windows, power seats, fan, not working hel

[ClipseAPG]

Hey guys, yesterday night while I was tightening my power steering belt, I accidentally touched the alt with a wrench and a big spark came of it. I thought not much of it and went inside the car after my job was "done" and tested out the car (to see if the loud squeal I heard at startup was gone) no squeal. But then, I turned on the headlights and the horn went off and wouldn't stop until i finally disconnected my battery. I started the car again to see if maybe i had just done something stupid but now, (after starting the car with no problem) I tried to turn the headlights off and again, the horn went off and I rushed under my hood to disconnect the battery (it was the middle of the night and I'm sure the neighbors didn't want to hear a horn) I called it quits till today where I would try to see what was going on. I forgot about the horn problem until it popped up again. First the headlights wouldn't turn off (no horn this time) then I noticed my radio didn't work, I disconnected the battery started the car up again and the horn came...so again, off to the battery. I forget how many times I did this but eventually I came to this conclusion;



( THIS IS THE PROBLEM FOR THOSE THAT DON'T WANT TO READ THE ABOVE PARAGRAPH) The headlights stay on when turned on, when tried to turn off or when they turn on the horn may kick in until I disconnect the battery, also, the radio, fan, and all power options are not functional (meaning windows, locks and seats) to clear it up though , all the interior lights and backup, high beams etc still work fine.

Please let me know what I can do to solve this, because I have seen other similar posts but those only seemed to either have headlights and horn problem but power options still functional, or headlights or horn or headlights with non-functioning interior lights.

Blown main fuse check your engine bay fuse box.

You mean just the 100 amp alternator fuse? Could that cause all other power accessories to disable too? or do I have to replace the power window, door, seat etc.. fuse(s) and fuse to radio etc.. too?

 

[heckles]

its the big one, I recently popped the same fuse tightening my alt hinge bolt nut. I know I should have replaced it but i was in a rush. Soldering saved the day again.

So just replacing the fuse 2nd to left on the fuse box (meaning the 100amp fuse labeled as alternator choke (or something similar)) should fix the headlight/horn issue and get the power accessories, blower fan, and radio up and running again?

well check if its blow first but yah

Hey, sorry to bring up old thread, but I had the almost same problems, I got a another alternator and the lighst are gone, I replaced the alt. choke fuse, but almost everything is back, but my p.window and radio. Oh, I did checked all the fuses and make sure the window is not locked. The fuses looks fine tho. Please help.
Please help.

I know this is an old post... But non of my power options are working, and at first I thought it was because of the battery and needing a new alternator. I picked it up from body shop and windows wouldn't roll down until I was driving it. Now that new alternator and battery are in the windows won't roll up, power seat wont work, stereo doesn't work ac doesn't turn on, and mirrors don't adjust. What could this be I'll try the alternator choke fuse, but I'm pretty sure mines ok. Any ideas?
