Electrical issue after 50trm install HELP!

[eclipse93b]

Okay so after a few weeks of hell and not having access to the talon for that long due to incorrect parts, rust, and other issues I just got the talon back/running tonight. There is a LARGE problem that I really need help with and I have searched for similar issues in the problem diagnosis forum, but to no avail I have come up empty handed.

My buddy who was doing the install noticed while putting the radiator back in that there was a wiring harness that was sticking out of the loom under the radiator. The wires were slightly exposed to the elements so he decided to wrap them in electrical tape and put them back in the loom... Well it turns out he didn't disconnect the battery and when he was wrapping the wires two of them sparked and the headlights turned on and stayed on (even when the switch was off), the horn also turned on and stayed on. He checked the relays and fuses (quickly) and he even changed the relay for the lights and it didnt seem to do anything. After pulling the fuses for each respectively they both went off. However, when I picked up the car this afternoon he said the issues were fixed so I tested the lights and they worked fine, then I tested the horn and the horn stayed on continuously and the lights turned on and stayed on as well. The car drives great however... SAFC dash lights everything worked great for the most part. Then when I got home (because I had to have the car for work) I went to lock the doors with my fob and nothing happened. I checked the batteries and they were fine, so I tried to lock the doors via the switch and they didnt work at all, I have to manually lock each door. The odd thing is that the windows work (along with the sunroof). After that I decided to check what else was not working right and I know they all must be connected. The HVAC system doesnt work, the radio doesnt work (ie no power)... I need to get this problem solved sooner rather than later and I dont want the car to be gone for another month in the process. If anybody could give me an idea as to what could be causing the issue with all of these components (recap)

- horn stays on continously (only when hitting the button)
- headlights stay on (regardless of switch position) only after the horn is going, though if they are on and you turn the switch off the taillights turn off but the headlights still stay on...
- HVAC doesnt work
- Radio doesnt work
- Key fob doesnt work
- interior map lights dont work
- door switches (to turn on map light/door ajar) dont work
- lock switch on doors dont work (though the windows do)

Any help is needed and appreciated.

Sounds like you have a short to power some where.. id go and pull the wires back out where he taped them and trace.. the others could be a fuse..

when he wrapped them, were any of the wires missing the plastic part around it so the wire was exposed? Maybe two of the wires are crossed or soemthing.

yeah, he said the wires were slightly exposed and it caused a quick spark. He checked the relays and they are good... I was going to double check his work tonight when I get home but I was wondering if it was anything anybody had heard of before. I know on Nissan's the Smart Entry Control Unit can cause issues like this if it is grounded, though I dont know if I have a similar setup on the Talon. Any other suggestions on where to look. I know that harness went to the fuse box under the hood.

Okay so I checked the fuses under the dash and only about 4 of them have power, is there a schematic on which fuses do? I haven't had a chance to check the ones under the hood or the relays, though I am going to check them tonight. How do I check the relays to see if they are still okay??

I finally figured out what the issue was with the car and I must say I feel like a major newb. When this issue arose I had checked the fuses and relays and they were all fine. I checked them again and I found that the 60amp yellow fuseable link was blown at the base of the fuse inside the plastic sleeve, which made it very difficult to see. I ordered a new one and will update if it solved the issue soon... meaning it didnt pop when a new one goes in again.
