headlights and fogs are dead Options

[lagos]

driving home today, i noticed that my headlights and foglights have no power, but the high beams work. i checked the fuses and i can hear the relay click over. i also did a visual inspection of the bulbs and they seemed ok.

so i did some more testing, it seems to be a grounding issue. i get 12v right at the red wire from the bulb harness, with the mutimeter balck touching a chasis ground poit, but if i just stick the multi meter into the harness plug i get nothing.

any ideas? i guess as a last resort, i could just spice in a wire and attach it to the chasis as a ghetto rig, but id like to know why its happeneing in the 1st place.

trace your wires inch by inch back, u may have possible broke connection somewhere. i have the toyota electrical dealer cat. if u need i can scan and email some other pages but there for 5sfe only, i dunno what or if any changes were made with your swap? i dont think it should interfer but never did it.....


let me know jon

It's been so long that I can't even remember...are the headlight relays easily accessible under the hood?

do any of you guys know how the ground wires run from the headlights? i have a totyota book, and read the diagram, but id like a visual or a pic .

i reading the diagrams i figured out that the headlight and fogs get ground through the same wire. i disconnected my fog lights and touched the ground wire to my fmic (yet another good use for a fmic ) and the lights came on. so for now im going to rig it up to my own ground and go from there.. but id like to figure out why this happened in the 1st place.

it should have nothing to do with my 3sgte wiring, beacuse the lights for the car are part of the body harness.

Are the low beams switched on by ground or by +12volts?

I can't remember how the low beams are set up, but if I remember right, the high beams are switched by ground. At least I think...but thinking has gotten me no-where today.

no, everything is turned on through the 12v line. i extended the ground wire from my fogs and connected it to the body with a 10mm bolt. everything is back to normal. i just wish i knew how the hell this happened in the 1st place.
