Technical Why don't my turn signals flash off and on?

That's possible, but he has also noted that the flasher connections are reversed at the socket and that does make a difference with some if not all flashers. The flasher terminals are identified for a reason....

 

Agreed! The problem is in/at the flasher. That’s is where I would spend my time first, in my search for the problem. The flasher is not functioning!

So why are you connecting there for testing? That should have zero to do with the turn signals...

I'll repeat; the X or power-in terminal on the flasher should have the 12V feed. The L (load) terminal should go directly to the turn switch for input power. If that's not what you have (and you said you don't), the turns won't work.

Check this: does the 12V power in the flasher socket disappear when you pull the turn signal fuse?

 

I spent 3 days chasing the same problem, tried the same things you have, I did have a new and 4 old flashers but was not able to get it to flash. If your sockets rely on the housing for ground, even though you have blasted and painted them you still may not have an adequate path to ground. Give it a try, easy and it can’t hurt.

 

If I'm reading the 53 diagram correctly the green jumper needs to be there for both brake lights to work.

 

You won't get power from the side of the flasher plug that goes to the turn signal switch on any vehicle.
You shouldn't have continuity or an ohm reading on that side unless you have the turn signal switch turned to either left or right. Simply meaning that the circuit dead ends at the switch until you turn the switch left or right.

If you have power to the hot pin on the flasher plug when the key is on you should be good. If you put your jumper wire in you should have power at the switch That would be the next thing I checked. follow the power trail from the starting point on as Steve said way back there.

 

I think you misunderstood me. There are 2 sockets for flashers. I'm working on the one in the top right corner, in the brown circle. The socket on the lower left circled in white, I believe is for the hazard flashers.



I noticed when I took a reading with the flashers unplugged the bottom terminal in the brown circle was 12v (we know that) and the bottom terminal in the white circle was also 12v. The white circled one is oriented so the 'X' terminal in the flasher corresponds to the 12v terminal in the socket. Could that be the socket for turns? I plugged in the flasher there and still nothing.

Also, I pulled the 15a T/S fuse and that lower terminal still read 12v.

 

try jumper in white circled prongs then see if flasher works

 

I got a little mixed up with all the talk. The 4 ways should work with the key off. Hot all the time. NOW, funny story, I had an off topic 72 nova. I took it to our local shop to have inspected because at the time we still had inspections. I brought it home and when I would step on the brake the front park lights would come on. Took it back and they tore the turn assy apart and said they didn't see anything wrong. Turns out they put 1156 single element bulbs in the front park light, dual element housings. When you stepped on the brakes they came on. Just a story for thought.

 

This is correct.

Which lower terminal? Pulling that fuse should kill any power at brown circled flasher.

 

You need to trace both where the turn signal power from the fuse goes and where the wires in the socket go....

It's looking like something is mis-wired at the fuse panel, maybe the panel itself is wrong. If pulling the fuse didn't remove power from the signals, where are they fed from?

Try this: find a 12V source (any one will work) and connect it to the X terminal on the flasher (with the flasher out of the socket). Then connect a wire to the L terminal on the flasher and connect the other end to your turn switch signal input wire, disconnecting whatever is currently connected. If the signals now work, the problem is the panel is mis-wired. If they still don't work, then it's a bad flasher or bad/mis-wired switch, in addition to a mis-wired panel. You may have more than one problem...

 

I'll jump on it again tomorrow. Thanks everyone for bearing with me!

 

That’s the toughest kinda of problems! The kinda that come in pairs! ......or threes!

Maybe your luck is better than mine, but my experience with Painless Wiring was far from painless. I was not impressed with a harness I bought from them for a VW Bug....it didn't even have the wires for the back signal lights, and the rear harness was 2' too short! Never fooled with them again.

 

PROBLEM SOLVED!! All turn signals flash, brake lights work, etc.!
I followed CrazySteve's above post and all is good! Hooked the 'X' directly to battery and the 'L' directly to the T/S
switch. So, it looks like the issue is the Painless fusebox wiring. I just found and ordered this off of Ebay......
https://www.ebay.com/itm/POLARITY-R...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

For $6, why not! That'll put polarity in the proper position then I'll run a wire from 'X' to 'ON' at my ignition switch making it a keyed source.
Thanks to all for the helpful input! The HAMB rocks!

 

Polarity reverser for a flasher; what next! Someone (in a land across the Pacific) must have looked at the print for the UPac flasher from the wrong side; kinda like some people wire trailer plugs.

 

I have no answer, all I can say is that this post makes my brain hurt. And I am always confused every time I wire turn signals. When they work, it's magic.

 

I am with Rich the only thing I see is a drain on your wallet.good luck

 

I'd say the problem is diagnosed, but not yet fully solved; you still have issues in the panel and I'd be very hesitant to ignore them. The fact that the 'turn signal' fuse isn't the one supplying power to the socket is troubling. You have at least one other circuit mis-labeled, whichever fuse is feeding the turn flasher socket.

You mentioned that the 'hazard' socket had the correct polarity. Is it possible that the socket positions are reversed? The hazard socket was wired as turns and vice-versa?

 

That is possible however, I tried running the flasher off the hazard socket and the turns still didn't work. I'm gonna pull the panel, find the wire that's supposed to feed 'X' in the turn socket, splice into that, fuse it and run it to my 'on' at the ign sw. Then a wire from 'L' to T/S sw.
This Painless harness is turning out to be rather Painful!

 

Turn signals aren't supposed to flash "off and on".
They're supposed to flash on and off.
Good thing I stopped by.

 

There are flashers for led bulbs that do not care about loads. If you have a heavy duty flasher they are meant for cars that are pulling trailers where the load is more.
