Turn signals wont work...?

[Ricmond84chevy]

I have a 84 chevy i just bought a few days ago the tail lights have been shaved and theres a line of fire wired in for the tail lights. when you turn the lights on the line of fire comes on but turn signals and brake lights dont come on and the right blinker light on the dash stays lit up.. And when u try to use the left blinker the light doesnt come on nor blinks.. Is it a switch problem?? I need help plz and thank you!

Sound like a back feed ground to me. You only have 4 wires that run to the rear of the frame. Im not sure about the colors but this is what each wire powers.

Red-tail light or running lights/licence plate light
yellow-left turn/brake light
brown-right turn/brake light
white-back up light

All the light are ground to chassis.

Ok ill check into that! Thanks. But the tag light wire is in the very back and it runs out of the wire loom and its brown, cant remember all the wire colors that run to the back. The truck is in my buddys shop so i cant go check but i def didnt see a red wire i will check tomorrow and let u know! Thanks!

Yellow to left turn signal.
Green to right turn signal.
Light green to reverse lights.
Brown to tail, side marker lights and tag lights.
All Blacks to body ground.
If all wiring is correct. Check fuses. Check flashers(turn and hazard). If all are good, it probably has a bad turn signal/horn switch assy. in the steering column.

Read the bottom paragraph - that appears to be the entire electrical installation instructions:

It is hard to diagnose electrical issues in a forum like this but do bear in mind that the Line- Of Fire light strings are composed of a bunch of LEDS wired in series.

The D in LED stands for diode. The point is - a diode acts just like a check valve in an electrical circuit. Current will pass through it but only when wired correctly (i.e. in the positive to negative direction) This is not an issue with incandescent lamps so people get used to ignoring polarity.

Okay so i checked the marker lights up front to see if any bulbs were out that might be throwin everything off.. The right side works but left side doesnt. But i checked it with volt meter and there is power gettin to but wont come on and its a new bulb.. Any ideas?

This is how the markers illuminate (and flash out of synch with the parks):

Note the first part of the text in the bottom image.


It would seem that, since current flow through an LED is only in one direction, the parking/marker lamp circuit won't work normally. Like it did when all the lamps were incandescent.


Good reading on LED's here:
