Title: marker light trouble
Post by: CarlBengston on March 13, 2015, 02:12:16 pm
I've got a new light problem. My headlights/brake lights/blinkers work but none of the marker lights come on when I pull the switch. Is there a common fuse for these? Circuits 9/40/44

So I don't have power at the t/l ctsy fuse or the instrument light fuses. I have power going into my light switch but not leaving through the dark green/brown/orange wires. It's a new switch

Have you looked at the wiring schematics in the Tech section?  Have you checked all your bulbs? Checked for power at the socket at the bulbs?

I've run through all the wiring diagrams. Checked bulbs/housings. I'm not getting power that far. I've got power from the red wire running into the headlight switch. But only the yellow wire coming out has power. The green/orange/brown that run the marker lights don't have power. But it's a new switch.

I only have power out of the switch to the headlights. No power to the rest of the lights
