Turn Signals and Parking Lights issue

[ammachine390]

Have been dealing with issues on my 68 Satellite since I got it in August. Tail lights and brake lights work correctly using 1157 bulbs. Parking lights turned on, and front marker lights light up with the brighter filament (1157 bulbs again). Turn headlights on, and left parking light goes out.

Turn signals do not appear to function at all currently. Rear signals will light up, but not flash. I have checked the voltage on the front park/turn lights, and the terminal that has voltage with the parking light on corresponds to the brighter filament. As it it now, looking into the socket, the terminal on the left has voltage with the parking lights on. Flashing voltage corresponds to dimmer filament. Is it possible to reverse the terminals in the sockets? Could someone had messed this up previously? Grounds appear to be good.

Suspect defective turn signal switch causing these problems

Check the ground again,add a ground to see what happens. I had a bad ground on my Bee and that was causing my tail lights from working properly.

When electrical systems do goofy things you check 3 things. The ground, the ground and the ground.

Double checked the grounds today and they were good. I checked for voltage on the bulkhead connector for the parking lights. That works as it should, power in parking lights, no power when headlights are on. Looked at the harness near the front passenger side (parking light that stayed on with headlights on) and discovered some electrical tape ups. I undid all the electrical tape and one of the wires was just taped up together but not used. I checked voltage to determine the power wires for the signals, parking lights and side markers. I think someone had previously tried to wire it it keep the the parking lights on with the headlights. Connecting the wires properly, and the passenger side functions as it should.

Unfortunately, when I was trying to unscrew the side marker lights, the housing broke as they were corroded? Are those still produced?

Also, my car has the fender turn signal indicators, however, I am missing one of the orange screw in lenses? Are those still produced?

I think I will rewire the parking lights to stay on with the headlights, from what I understand, that's easy to do on the switch itself. I believe I can also get the side marker to flash with the turn signal as I was able to do that on my AMC.

I believe those pieces are reproduced.

The rear lights are indeed bulb 1157. The brighter filament is for the Brake/turn, the other for the parking/taillights. The rear turn signal is no more than the column flashing the brake light on that side. Its most likely wired incorrectly.

For anyone doing electrical repair pick yourself up a Power Probe 3.
Plenty of YouTube vids showing what you can do with it.
Put your test lights and meters in the bottom drawer because you will never use them again.

I've got a similar problem just got this 68 rr
383 4 speed numbers match.

-Headlights an running lights work
-Rear left brake light works
-4x only front left an rear left work

-No signals at all
-no rear right brake light

Ordered a turn signal switch an a wire diagram. But last night I seen that the signal light flasher was hanging by one wire both were burnt. I need to rewire the turn signal flasher. I have to figure out where those two wires from the flasher go too.

When I first got it two weeks ago I had no lights but head lights.

In 1968 the parking lights do not lite with the headlamps.

If you want the parking lights with the headlamp it is a easy change. Buy two 2N1007 and place the cathode (line on the diode) to the parking lamp pins on the switch. Place the anode to the headlamp switch position.

So when the head lights are turned on the running lights stay on in the front right

I'm worried about the signal lights burnt up turn signal flasher wires.

I also seen someone had fixed up wires going to the ignition switch wonder if that caused it. Can't wait to get my wire diagram

It might be time to buy a painless wiring kit

Why are you waiting for a wiring diagram.. it's either in the FSM you should have in your possession or on mymopar.com

Yea ehh I pulled the seat so I can get right down under there. You ever put one in a mopar? Thanks for the replys ehh

 

[ramchager63]

Seen one goes up to acc on the ignition switch other splits into tow one goes to the stop light switch other over to emergency flasher switch

I am still having the issue with the driver's side lights. I disconnected the all the plug connections and tested for voltage and confirmed the circuits for the front marker light, the turn signal, and the side marker all work correctly and the wires match with the diagram. Everything on the harness end is working correctly.

As a final check with the turn signal/front marker light harness disconnected, I used a jumper and applied voltage directly to the harness that goes to the bulb. With voltage applied to the turn signal (the female end on the light side of the plug, see picture), the parking light lights up. With voltage applied to the parking light side (male end on light side of plug) the turn signal lights up.

So somehow, something is backwards in the small harness that goes to the socket. It does not appear that the harness was ever cut. Is there a way to remove the socket and switch the wires at the terminals? Thanks.

(It's not a faulty bulb either, I have tried other bulbs and gotten the same result)

It easier just to jump out the front and rear circuits on headlight switch like factory did.

Or even easier, but maybe not cleaner... get the source straight from sidemarkers without anything that a jumper wire. Which will be the same than feed them from headlight switch since the rear circuit is what feeds all sidemarkers. The jumper at headlight switch is cleaner.
