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? |

corrosion on contacts make a high resistance and cause a high amp load on the circuit melting the relay socket, or some one put in higher wattage bulbs in 35 watt fog light and melted relay socket.

So the relay could check out, but still be an issue with the heat? I guess I should stick one of the spares in and see what happens. The bulbs are stock from a 73, I'll have to check, but I am pretty sure they are 35w. |
