I can’t see chit!!

Well I have one for yaw' guys!

My front passenger side parking light (the light below my headlight) is out, the bulb is fine,

When I took the bulb out the passengers’ side marker light (the small light on the front quarter panel of the truck) goes on, I put a good bulb in the front parking light and the side marker goes out!

I am reading 12v on one of the contacts on the bottom of the parking light socket and 6ish V on the other, I have one wire that looks as if it might have come out; but when I push it back up the side (this is the 3rd wire in the socket (black I believe), so there are two wires next to each other, then one outboard a bit- this is that wire) no change!

Any ideas, I know it is something stupid I am missing


Thanks,

CHECK THE GROUNDS!!!! its the most common issue with lights

the 6v line is for the marker lights, 12v gives you the turn signal

....so should I be getting both 12 & 6V when I just have the lights on (turn signal in neutral; non flashing position)?

Also since the light is really up in the truck, where is the ground for that parking light?

 

[CCATLETT1984]

no, only should be getting 6v on the wire with just the running lights on.

I am unsure if they ran the ground into the truck or just onto the radiator support.

Any idea why I am getting 6v at one of the contacts in the bottom of the lightbulb socket and 12v on the other contact? w.o the signal activated (I just have the parking lights on)????

i know its a pain, but check the plug on the other side of the truck just to be sure.

you may have a relay stuck in the on position

Those turn signal light sockets are prone to having a problem with the ground connection to the bulb. A sign of this is if when you turn on the head lights, the green arrow for the turn signal indicator on the dash will stay lit. Any auto parts store will have a replacement for this bulb socket. The color of the wires may not match, but their positioning on the light socket makes it easy to splice into the correct wires on the harness.

Looking at the wiring diagram in the back of the -20 manual, the side marker lights do not have a direct ground. They seem to ground through the turn light circuit. That is why you read a lower voltage on one of the terminals, it is the voltage drop caused by the side marker light bulb. Do you get 12 volts alternating with 6 v with the flashers on? Do the emergency flashers work?

I would follow the black wire to were it bolts to the frame and clean it first.

I was composing my post at the same time as dilvoy was and didn't see his. It could be a bad ground in the socket to. You might be able to test both with a multimeter by checking the resistance to ground in the socket.

I hate it when that happens....

.....er it's the ground, pushed a spare piece of wire I had into there and grounded it & viola, we have light!

Hey george, hows it going!
