Another post about blinkers...

[truck-collector]

The blinkers on my 67 wont work-nothing lights up outside or on the dash. Everything DOES work with the e-flashers though. I have replaced both flashers in the dash (behind the cluster and behind the radio) as well as the TSS (from LMC). I am getting power to the ts cam and if I put a jumper wire from the light blue wire on the cam to one of the contacts below the flasher makes noise, but nothing lights up. Plus when I do this I get some smoke as if its getting too hot. I did notice that my blower motor isnt working and it seems like I saw a post on here that said that in some strange way the two are linked? Maybe I misunderstood that part. Any help would be GREATLY appreciated.

I had the same problem. Mine turned out to be bad grounds. Clean all of your grounds. Your light sockets may need to be cleaned out also. Just something to try.

Hey truck-collector...

If the lights all work with the 4 way flashers on, then it probably isn't a ground problem.

Do the lights come on when you hit the turn signal but not flash or do they not come on at all?
If they come on and not flash, then it could be the flasher unit.
Our trucks have two of them. One for e-flashers and one for turn signals.
If they don't come on at all, check the connecter that comes out of the steering column... the contacts can get corroded and not make contact.
There is a high probability that it is the turn signal switch itself...
You can pull the steering wheel and visually inspect it.
You can use a simple test light to see if the switch is getting power, and see if it is working properly.

He walked me though installing my new one.

Good luck...

those are tied to gether the blinker, blower and the wiper washer pump. I bet if you pulled out on the wiper switch a little the pump doesnt work. on my 67 i had the same problem and had found out that the circuit had no power at all.

I traced it out and found nothing wrong and ended up putting a fused(rated the same as normal circuit)power switched line in to make it work. But only do what i did as a last resort.

Here's the '67 diagram from the tech section...
You can trace down your circuits with it...

Because you are having problems there at the switch, I am still guessing the switch...
You might try disconnecting the heater and jumper it to see if it works independently...

you might wanna shoot him a PM and describe what's goin' on to him...

Thanks for the advice. When I replaced the turn signal switch at first the right blinker would light up on the dash, but then it stopped too (wasnt blinking though as I hadnt changed the flasher yet). I am getting power to the steering column. Once the power gets to the turn signal switch towards the steering wheel, where does it go from there?

[seattle67]

The power for your blinkers comes to the TSS on the blue wire, it goes out as follows:

Front R.H. turn signal - white/blue stripe
Rear R.H. turn signal - green
Front L.H. turn signal - green/white strip
Rear L.H. turn signal - yellow

The first thing I would do is make sure you have +12vdc on that blue wire.

Just fyi, the power for your brake lights, supplied by the brake light switch when you push on the brake pedal, comes to the TSS on the red/black stripe. And, just to be confusing, the power for your emergency flasher also comes in to the TSS on that same red/black stripe wire.

edit: I may as well take this a little further.

When the TSS is centered, (no left or right blinker) the red/black stripe wire is connected, through the contacts in the TSS, to the yellow wire and the green wire. This connection is what feeds your brake lights when you push on the brake light pedal. This same connection is what feeds your rear lights when you flip on the emergency flashers.

Ok, flip the TSS as if you are going to make a right hand turn and the following happens:

1 - The connection between the red/black stripe wire and the green wire opens. With this connection open pushing on the brake pedal will no longer light up your right brake light, now the flasher has control of that light.

2 - A connection is made between the blue wire (flasher power in), white/blue stripe wire (front R.H. blinker) and the green wire (rear R.H. blinker). You should now have right blinkers.

3. The connection between the red/black stripe wire and the yellow wire remains closed. This allows your left brake light to be operational when the TSS is in the right turn position.


Flipping the TSS to the left turn position and the following happens:

1 - The connection between the red/black stripe wire and the yellow wire opens. With this connection open pushing on the brake pedal will no longer light up your left brake light, now the flasher has control of that light.

2 - A connection is made between the blue wire (flasher power in), green/white stripe wire (front L.H. blinker) and the yellow wire (rear L.H. blinker). You should now have left blinkers.

3. The connection between the red/black stripe wire and the green wire remains closed. This allows your right brake light to be operational when the TSS is in the left turn position.


The emergency flasher uses the same circuit through the TSS as the brake switch to flash the rear lights, but sends power directly from the emergency flasher switch to the front lights.

the blue wire like Seattle67 said is the power and in the circuit should be the heater blower switch and the ?washer pump?( when i tested mine i didnt have wiper blades on my truck so im not sure). If none of those work you should check the circuit close to the fuse box for power or check to see if the fuse is blown. If the fuse is blown it could have shorted out some where which could be from serveral things. a frayed or broken wire or best case a bad fuse. There could also just be a bad connection/corroded at the fuse its self.

As ive said before my problem was cause i had no power to the circuit at all and i when i traced every thing out i couldnt find the problem.

I looked for the post where i had this problem but cant find it. If i remember correctlly the 67 goes to the heater motor then to the washer switch and then turn signals.

edit: found it http://www.fordification.com/forum/view ... highlight=

the only thing not on there was how it was fixed

sorry i misread the post. My bad.

[truck-collector]

Thanks everyone. Ok, I checked the fuse and it was blown, so I replaced it and now my heater is working (I think I blew this fuse while I was messing with the wires going to the TSS). I have discovered that if I step on my brakes and turn the left turn signal on it does not flash (ie goes dark) while the other side is lit still. If I turn the right turn signal on neither lights work while the brakes are on. Is it all in my TSS? I just replaced it in around July 4th-could it be bad or could I have the wrong wires connected?

[SteveC]

hmmm then id check the wiring from the heater motor to the wiper switch and then to the turn signal.

[Thunderfoot]

I think you have some wires in the wrong places to the TSS... A lot of the replacement TSS’s don't have the exact colors to match up correctly.

The symptom you have with turning on the right turn with the brake lights applied and both going out tells me that you might have the brake light and right rear light swapped to the TSS... If you look at the top part of the diagram I have below (note this is from the 68 but the wire colors and wiring are the same just some different numbers), I think you have wires #5 and #10 switched...

I also think you might have #2 and #44 switched... which would make it so that the turns will not work.

If after swapping those wires nothing changes go to the next step I have here, if you get some results let me know what is working and what isn't and I might be able to figure out what other wires may be switched...

Here is a easy test you can do to find out if everything else in the truck works minus the TSS.

Take a short piece of wire and strip both ends of it so that you can use it as a jumper wire.
Unplug both of the connectors to the TSS.

Now just working with the half of the connectors for the truck side (not the ones to the TSS) find the Blue wire, should be #44 location on the connector and it will be hot with the key in ACC.

Use the jumper wire and go between #44 and #282 (Green) wire, this should make the right rear light flash. (Note: or at least the light will come on, this will be the same for the below checks as well)

Then go from #44 to #283 (Yellow) or (Yellow-black stripe) wire, this should make the left rear light flash.

Then go from #44 to #2 (White - Blue stripe) wire, this should make the right front light flash along with the dash turn indicator.

Then go from #44 to #3 (Green - White stripe) wire, this should make the left front light flash along with the dash turn indicator.

If you end up doing these tests let me know how it goes.

Also, let me know what you have for test tools. if you have a test light or volt meter and an Ohm meter. This will let me know how to make instructions to help.

Mystery solved! After doing the test (power to each blinker) that Thunderfoot suggested, I found everything to be working. This narrowed it down to the TSS. I decided to take the TSS apart (hey it wasnt working so who cares if I broke it right?). What I found was the whiskers were melted into the plastic and were not touching the nubs. Why was it melted you ask? When I replaced the TSS my blinkers and my brake lights were not working. Everything I read on here pointed to the TSS. I replaced the TSS but I kept blowing fuses and evidently during one of these episodes the whiskers in the TSS got so hot that they embedded themselves into the plastic. Why was I blowing fuses? Well I put air bags on the back of my truck. To put the airbags on the back of the truck I had to put some brackets on the frame via bolts. One of these bolts pinched the wires to the brake lights, causing a short. Thanks to everything for their help and suggestions! I will be posting some pics of my 67 shortly.

[Thunderfoot]

glad you got it narrowed down and figured out!

Looking forwards to seeing your truck! plus the airbag setup
