Hi All:

About twice during the past year and a half, my dash light out warning would come on. Each time I would just wiggle the passenger side tail light and it would begin working again, until yesterday. I wiggled it, tested the bulb and still it would not come on.

I got my multimeter and tested the voltage at the bulb socket. It fluctuated between 3.5 and 4.2 Volts. I tested it at the incoming wire connector, and it was about the same. I checked the resistance and it was only .03 as compared to a light that was working which was .02. I'm really not sure why, but I then went to retest the voltage at the incoming socket and it was 7.4 Volts. I then tested it at the bulb socket and it was 7.4 for a short time and then it went as high as 10 volts, but when I twisted the bulb in, it would not light, and the next time I tested the voltage it was back down to 3 and 4 volts.

I have checked the fuse and cleaned the fuse connectors, but the truth be known, I am really stumped! Can anyone give me some clues as to what is going on, where to check, etc.?

Thanks much, I really appreciate any advice you could give.
