'84 turn signal electrical problem

Ok guys. My turn signal is not working. All other lights are. Upon checking the bulb (not the problem) I found this ground? But I can't figure out where it belongs? My electrical skills are consist of plugging and unplugging

That's not a ground wire. It should run across the radiator to the other light and then to the side clearance light. Your ground wire is attached at the top of the grill on the inside there should be a sheet metal screw that the ground will attach to. It is on the inside. Looks like the wire has become disconnected. That is why your lights aren't working.

Those aren't stock wire colours. The signals ground through their case so the case has to be bolted in place for them to work. The fronts have a special shoulder screw for this.

have you checked the fuses and the flasher itself? Do they light up or not or just don't flash?

Do the emergency flashers work? They are a different fuse.

Grounds are 'usually' black. Though I did run all white for the ground in my fibreglass body so it 'might' be one, but not real likely in my mind.

All other signals work when flashers are on. The white wire is connected "with" the ground on the inside via sheet metal screw. It's such a clean cut?

I'll reattach with new bulb. I didn't know about case having to be bolted for the ground to loop. Hopefully it's something as simple as that. Maybe the previous owner had some kind of accessory up front.

Thanks!

I'll advise....

Okay guys, we're getting close. The bulb will come on when I turn on the running lights. But... It will not flash? All the lights work including the side marker lights. ?????

Thanks! (again)

Now you are getting someplace. If only the one bulb doesn't work with the emergency flashers and the bulb is new and the case is for sure grounded with that special shoulder screw, it implies to me that one circuit has issues.

Those bulbs are sneaky, they can short in behind the glass which is why I don't just look at them, I pull them out to see.

Did you hook that white wire up to anything? There are supposed to be 3 wires coming out of the back of that light fixture. The running lights, their ground wire going to the back if the grill and the signal wire I believe.

Have you checked the fuse for the signals? It is top left on the panel.

It's the darnedest thing. I checked the fuses, are all good. The rear turn signal works. Switched bulbs no difference. Bulb illuminates when headlights turned on. Just no hazard or turn. Could it be signal itself?

I looked at both fixtures. Only two wires come from them.

OK, the ground is a different feed. The side marker light is ties to the signals, it would be worth a check.

Ok so the wire is supposed to be connected to the plug coming from the vehicle. That plugs into to the fixture connection?

The extra white wire?

No, just two wires were all that was ever used. However...

That hole in the back of the reflector looks as is someone might of connected a grounding lug with a screw to light to insure a good ground.
Something like this:



Can you tell is both filaments light up with the headlights on or just one...

Only 1 filament lights up(now we're getting somewhere). No additional grounds are attached to either fixture. And haven't been for the last 10 years(since I've owned it).

Do what John did. It fixed my turn signal issues that were driving me nuts.
