Ok hopefully someone can help me with as I been trying to troubleshoot it for 3 hours... As I was aligning my Driverside headlight to the fender and hood, my driverside headlight quit working ( The headlights retracted about 10 times while doing this). Before aligning both were working properly. With a voltmeter I checked the DC Volts coming from where the headlight bulb connects to the connector and read nothing. Passenger check ok with 12.03 V. I checked further down to the Driverside Headlight connector to where it connects to the main harness and it read 13.77 V. I cut the wiring as to hotwire the headlight to see if I get lights and nothing ( which is coming from the connector which connects to harness).<--- This should have worked due to my voltmeter readings earlier. The Driverside fuse under the hood is good. All fuses in the cabin are good. My conclusions are:1. That the driverside fuse shares a fuse with someother component(s) and that went bad. (but visual check on all fuses are good.

2. That there is a fusible link that I missed (anyone know about this?)

3. I shouldn't have tried to align the f*ckin headlight in the 1st place

My day job (military) deals alot with electronics and I've been through school for electronics so for the most part I know what I'm doing and about troubleshooting components, but I am done F*cking with it.

Sorry for the long *** post but I thought one of you gurus would know whar to do. PLEASE HELP!!!!

try pulling the fuse and check for continuity. it might not be burnt at the designated area. BUt on the side.

Ok got the problem fixed. Seems like It went out when I had to use a hammer to adjust some of the rad support. As I was doing a mod with my hood as I hit the hood they lights miraculously came back on. Im thinking it was a loose connection some where. It was weird...but I got my lights on now!

You know it's gonna happen again. Check the ground ohms from the HL conn. also. If it's got a high resistance somewhere in it, 12V isn't going to do you much good. If the headlight is unplugged, volts don't mean a thing. Checking volts only helps if the original circuit is complete, ie. everything plugged in like it should be. I watched my dad do that dance for almost 2 hrs. one day on boat trailer, but he wouldn't let me near it because he was sure that "volts" was all that mattered. He finally gave up, and was pretty pissed when I turned his meter to 'Ohms' and found it in ~30 seconds, fixed it in ~5 mins.

You're right... Once I checked the ohms on it hopefully I will be able to kind of pinpoint where the weakness is coming from. It has to be somewhere in that electrical harness thats its run off of.
