Directionals Not Working

[Challenger RTA]

I'm implying to check each light socket by applying power to the plug,and touching the housing.not scratching off pant. Narrow it down by process of elimination. You might see something that's not right.If was a as simple as putting in a flasher you would be done. Find what works and don't work. You know the system doesn't work. Note I think there is a ground wire on the taillight assembly.

Makes sense I also think the problem is in the front of the car also. I installed a new directional relay and the brakes work--the rear flashers work but the fronts dont. The taillights and parking lights both come on but are very dim. And when I try the directionals the dash bulbs they stay solid lit. Should I run a ground with from each parking light to a ground? I dont see a ground wire in the trunk I remember when I had a 69 charger there was a ground wire in the middle by the latch mechanism I dont see that on a e body

What you are describing is the same problem I had. Like I sad unplug the side parking lights and the front parking-turn signal light. Also behind the driver's kick panel unplug that connector, that take's the rear out of the equation. Cut the wire off you wife's vacuum and you have a long enough cord to hook up to the battery
+ and -.
NO! don't do that. If I need a long test wire, I'll use zip cord. It's the house cord that you buy at the Dollar store. Dollar store! that's a whole other thing. Get 2 or 3 plug 2 together and cut one in half. Then plug the ends into the other ones and strip the ends. polarity,one side is smooth and the other is ribbed. get those.

I worked on the car today I changed the bulb on the left side and cleaned the socket. The guy from the shop spliced my drivers side directional where a wire had broken but he spliced 2 wires together and connected them to the housing im thinking one goes to the light and one to the ground ? not sure. I hooked up another separate ground wire from the radiator support to one side of the light and when I tried it the light didn't blink and stayed steady but was very bright like it should be not dull looking like the right side is now. So I guess I have to add a ground to the right side also but still can't get them to blink ill post a picture of what I have. Where's the ground wire for the rear taillights

The Diagram in #22 post does not show all the grounds. Every wire is power to a load. All grounds are achieved thought the body. As I said in a prior post for a test use a wire from battery - to the light housing that will be a good ground. The black with tan and the black with yellow will be your power for light.

That's the point of testing each light to know it works. And test it when the housing is mounted on the body. No it wont blink when you put direct power to it,it will stay on. Use a test light on the car side plug in each socket, one is the parking light it will stay on. the other side will blink being the turn signal.The cars thees days are wired a little different.

 

[KennyCuda]

ok thanks ill try testing each one

 

[Challenger RTA]

OK the top black and white is a in-general diagram of how the most turn signal switches are configured. The bottom color diagram didn't exist until I made it from other diagram. Or at lest I never seen one. It is the pin out of the turn signal plug under the column.
Unplug the connector.On the car plug apply power to each connector that you want to check. Except the horn.Touch to ground to compete the circuit. If the lights works and you still have a problem,it's in the turn signal switch or the power coming from the flashers.

 

[KennyCuda]

Ok thanks for the pictures the picture I posted there is 2 wires going to the wire with the crimped connector on it is that correct

 

[Challenger RTA]

Yes your just bypassing the plug. connect the same color wire together as you did.

 

[KennyCuda]

Ok thanks and can I add a ground wire in there also

 

[Challenger RTA]

Ok thanks and can I add a ground wire in there also

Yes you can. If you are saying to add a ground wire attached to housing for a ground. You should not need it but it won't effect anything.

Adding to @Challenger RTA 's last diagram to show the left side with the steering column connector and the Turn Signal Flasher (on the side of the ashtray).

thanks for the info I worked on something different today took a break from those crazy directionals

Have you verified key-switched power at the fuse for the radio/turn signals? If the four ways and the brake lights work, it’s not a ground issue at all. The pictured column ground wire is for the horn switch and gear shift indicator, if equipped, only,

In regard to the pictured 6" column ground wire, is that ONLY if you have a gear indicator on your column? I don't see one on my 73 Chally w/ a 4spd.

Should be there for the horn switch primarily, all cars had a horn.
