First of all, let me tell you that I had my corners light rewired, foglights rewired, and had a set of Cuzo sidemarkers installed with one wire that lead to the blinkers and the other one lead to the factory side markers. When I turned on my headlights, only the headlights went on, the foglights, corner lights, factory side markers, and the Cuzo sidemarkers(I wired these sidemarkers to go on when I turn on the headlights and flash when I use the turn signals)didn't go on. However, when I used the turn signals, the corner lights worked, but only when the turn signals were activated. When I deactivated the turn signals, the corner lights went off. Also, the Cuzo sidemarkers flashed when I used the signal lights. Although, the foglights still didn't work whatsoever. So, when I activated the signal lights, everything worked, except for the foglights. And all of the lights(except headlights) went back to not working order when I deactivated the turn signals. What the heck? I want to say that everything were working fine until yesterday. So, I know I didn't wired anything wrong. They all worked like they supposed to. And it can't be a fuse, can it because the lights did worked when I used the turn signals? I even checked the wires to see if there's any loose wires, but didn't found any. I did check some of the fuses, but didn't really check the fusible links though because there's no way I could check if they were bad or not. Could they be the problem? I need help guys. I tried everything that I know of. Thanks for any advice in advance.

the way in which you rewired these lights as it may help give a better understanding on how/what/why things went wrong. Perhaps there is a burned out bulb that is somehow preventing the others to work correctly. For example on my car I rewired the foglights to come on with parking lamps which always stay on by themselves, lowbeams and highbeams. This was done by taking the signal input wire from the foglamp relay and cutting it. I spliced a wire from the parking lamp that always receives 12 volts with or without a bulb installed and connected it to the signal input on the foglamp relay. Now had I spliced the wire on other side of the bulb (so to speak) or to the other wire, then if that bulb ever goes out, I would lose my 12 volt source to the relay so my foglights would not come on. Does that help any? That,s why I ask how they were rewired.

 

I solved my problem. I found out it was a burned out stop light fuse. Doh! I didn't know that a burned out stop light fuse could affect the rest of the lights. Geez...after I checked the wires, bulbs, and connectors, all I had to do was change a simple fuse. Smart, huh?

 

Don't be too surprised if the same fuse burns out again. Your modifications may have put too much load on this circuit.

If the fuse does burn out the fast, easy, and wrong action is to replace it with a higher rated fuse. The factory fuse rating was appropriate to the size of the wire in that circuit. Changing to a higher rating fuse without also upgrading the wires defeats the purpose of the fuse. You may end up with a "toasted" wiring harness and a big repair bill.

 

You know what? Yup, it burned out again. The fuse that the factory use was a 7.5A fuse, but I replaced it with a 10A fuse, I hope that will be good enough. However, I didn't change the wires, how do I go about that? Do I have to change all my wires?

 

You don't have to change all your wires, just the wiring on the circuit which has the additional load. Since you ask "how do I go about that?" I gather you don't have electronics skills, so you should pay a professional to do it for you.

You (or your hired technician) should consider using a relay to support the additional load. See http://lighting.mbz.org/tech/how_to/relays/ for information. That page doesn't cover your exact situation but the ideas are the same.

 

Well, I did all the rewiring on my car myself. If changing the wires is as easy as the rewiring, then I think I can do this myself. It's my tail light fuse that went out, so does this means that I have to change the wirings to my tail light? It sound strange because I don't think the tail light is handling the additional load, but for some reason, the tail light fuse went out. I would think that it's either the foglight, corner light, or parking light that is carrying the extra load.

I'm not criticizing you, but this sentence is evidence that you lack a full understanding and ought to hire a professional. The tail light is not handling the additional load, the tail light circuit is handling the additional load. That's why the tail light fuse has burned out twice already.

Wrong again. The foglight, corner light and parking light aren't carrying the extra load, they are the extra load.

Yes, and you deserve credit for trying... but your lack of understanding is what created this problem in the first place. Maybe you have a friend with electronics "savvy" who can coach you through this. What I'm trying to say, in a tactful way, is that you need to get help before this situation takes a turn for the worse.
