OK, I know enough about elec. to test a few things so here is what I found once home from Okteenerfest.
Fog lights, driving lights, whatever you want to call them just quit working. The pull knob lights up I get 12v in the front trunk at the connection from the main harness. (that is with the connection separated) {with all wire connected, I get no reading} Grounds have continuity there too. I did not get 12 volts once I took the light apart, not the bulb holder, just the light was apart and I used an alligator clip to ground it. No volts. If I remove the alligator clip from the hanging light in the picture below and put the red lead of the VM on the white/ylw wire at the bulb holder THEN the black lead of the VM to a bolt on the car..... I get 12 volts. So with the bulb holder or the complete fixture assembled and grounded I get nothing. What is going wrong here? |

Look at the bulb carefully to see if the tungsten filament is broke and sometimes making contact. If you tap it slightly you will see if it separates.

Look at the bulb carefully to see if the tungsten filament is broke and sometimes making contact. If you tap it slightly you will see if it separates. I get continuity and I lit it up. Plus both lights are out and went out at the same time. I was hoping to find someone that has the same problem or that could follow my description of the symptoms. I too feel that it could be related to ground. But, if I place the VM on continuity and one lead on the connector on the brown wire or the flat brass spring, both attached to the fixture and the other VM lead on a non-painted screw and get continuity, wouldn't that rule out that ground wire? If the + wire( wh/ylw) was touching metal, wouldn't the other stuff in the car being going crazy? And might I get continuity between the + lamp connection and ground or other non painted metal? |
