Help troubleshooting headlight problem.

1.) 1996, SVX Lsi, 96,000 Miles, USDM

2.) Modifications that could in any way be related to the issue. NONE

3.) My Left Front Low beam Headlight has stopped working. All other lights work fine. I was hit by a deer recently and the Left outside mirror was torn off, but all lights worked normally immediately following the incident.

4.) Report any environmental circumstances accompany the problem (e.g. only happens when it is raining.) NA

5.) Detail the current state of troubleshooting (i.e. Exactly what has already been attempted in an effort to fix the issue.) Checked Fuses, relays, and bulb. FUSE is OK, RELAY is OK, BULB is OK. I even swapped them out to be sure.

6.) Use your eyes and ears. Report all sounds, warning lights, and associated malfunction that accompany the problem. NA

7.) Advise level of technical experience - No use telling someone that a specific pulsoid or check valve may be involved, if they do not have a grasp of technical terms. I am quite familiar with the SVX as I have driven one since 1994. This one is My 7th SVX and I have a complete set of Factory Shop Manuals.

Re: Help troubleshooting headlight problem.

Almost has to be a bad wire or connector, from the sound of it...

Re: Help troubleshooting headlight problem.

Bad connector sounds plausible. With all the salt in our area, it happens a lot. I had to solder in my speakers to keep them from randomly disconnecting. I am going to solder in the third O2 sensor as well.

I will be at Maple Lawn Dairy after 7PM tonight. I can bring my DMM and grab some needle probes from work if you want to swing by.

Re: Help troubleshooting headlight problem.

Turns out I won't be there tonight. I might be in the area tomorrow, however.

Re: Help troubleshooting headlight problem.

I sent Trevor his post to research. Trevor replied with a lot of useful information and procedures to follow for a diagnosis. I sent KingLizard a PM with his observations.

I sent Trevor a copy of the USDM electrical manual (FSM) many years ago so he could diagnose many of the electriical problems here. His understanding of the electrical circuitry has always been spot-on and has never failed me. The value of information received from him over the years is priceless, and he still continues to give.
