Re: No brake lights

Tom -

Is the contact plate on the switch still flat? I have had switches where the contact plate was deformed (concave) so that the rod movement did not actuate it. My solution was to add another contact plate removed from an old switch to take up the slack.

Also make sure that the booster rod is the correct part.

Scott -
There is a diagram on my website for both the 1967 and 1968 Cougar turn signal switch pins (both sides). The pin orientation for the 1969 Cougar tilt switch is the same as the 1968. A 1969 Cougar standard column switch is similar but doesn't have the red wire, so that position is empty.

I stock both sides of the half-moon turn signal switch white connectors and pins.
Thanks for posting this. It looks like the 69 wiring colours are different from the 68. I have a cut plug I just acquired (vehicle harness to turn signal plug) that I am going to use as reference to fix Heather's 69. I will let you know how it goes. Do you want me to send you the wire colour sequence? Maybe you can create a 69 version of the turn signal connector file.

By the way, I clicked on the link to the BARGANSPOT site and noticed all the wiring harness stuff you do (which I didn't know that you did until today). Very nice.

Re: 1969 Cougar turn signal switch connector diagram

Scott -

The 1969 turn signal switch side connector wires are the same as the 1968 Cougar with the exception noted above.
Note: the diagram shows the connector wire colors from the pin side.

I'll update the diagram to show the wire color assignments for the car harness side, which is different for the 1969 & up Cougars.

I matched up the same colour wires on both sides based on the car harness plug I acquired. Tests so far show that they are working, except flashing very quickly (most likely need new flasher canisters).
I hope I'm not going to catch the car on fire.

I have a '70 Cougar, and the issue is with the park lamps on. When they are on, the turn signals do not work. Is it getting power from the from the headlamp switch, or the relay can under the dash is going bad? Or is there another issue I need to follow? i have replaced the turn signal switch due to other issues that are resolved.

I have cleaned up the battery contacts, and it seems to have worked. I don't pretend to understand it, but it works. All of my lights and turn signals work in all positions. So try cleaning your battery contacts in addition to your regular diagnostics.

Vic,

The Contact Plate Is still flat and on top of it the rod is the stock one that came with the original midland ross brake booster that is on my car, has not been changed in some time the only thing thats been changed is the master cylinder... The car sat from 91-2014 and we are still using the same booster. is it possible that maybe the booster could be bad? how can i tell? i don't have to put my foot to the floor to stop, and it has pretty decent stopping power at least to me. I'm just out of ideas... and unfortunately i do not have another plate to put back on it.

Replaced both flasher cans with new style solid state from the local auto parts store, but it did not solve the quick flashing of the turn signals or the emergency lights.
Anyone have a suggestion to fix this?

Scott

I read your post and have some questions and suggestions to troublehoot the issue.

When you say flasing very quickly. are the bulbs sequencing or is only the inner bulb flashing?
Are you using a stock sequencer or a newer solid state designed unit?
Are you using LED bulbs in the tailigts, front parking lamps and/or side markers?
When did the issue start to occur? Last changed item, first to be reverted/tested is my motto.

The components that affect the turn signal operations are as follows:
1. Charging system
2. Emergency flasher
3. Turn signal flasher
4. Brake light switch
5. Turn signal switch
6. Sequencer in the trunk
7. bulbs in the taillights, parking lamps and side marker lamps

Check your charging system, make sure the alternator is putting out 13.7 to 14.5 volts. Also check the battery condition and just as important the ground wires. Also make sure the ground wire to/from the sequencer in the trunk is clean and tight. It is very important to run all of your turn signal tests with the engine running.

Grounds, grounds grounds!!! Make sure the sequencers, bulbs and all electriconics are properly grounded. If a ground wire is not clean and attached properly, the power will search for a path of least resistance and ground through to another component with unintended results. For example, if a dual filament bulb is not grounded properly, the power will flow from one filament into the other and from there it will go to the path of least resistance.

I highly recommend for a first step in troublhooting especially if you are using a oem sequencer, is to use the appropriate incandescent bulbs throughout. Remember the OEM system was designed for the amperage draw for these bulbs.

Are you using LEDs in any of the taillights, rear marker lamps or front turn signal lamps? The original system was designed for use with incadescent bulbs not LEDs although the new solid state reproductions will work with LEDs BUT needs either an incadescent bulb in the front turn signal or a load resistor.

LEDs can have internal issues and have caused short circuits with unintended behaviors as JETEXAS posts viewtopic.php?f=3&t=8261 about his issue using LEDs.

Front Marker housings recently replaced? If I remember correctly, the Mustang housings are wired differently than those of the Cougars and again will wreak havoc with the system.

Good Luck

Coach Jack

Thanks for getting back to me Coach Jack.
They do sequence, but very quickly. Basically by the time it gets to the farthest outboard bulb and it starts to light, the system is off and then restarts the sequence
It appears to be the original sequencer in the trunk, no LEDs (although I was thinking of switching it all over for her).The front turn signal housings and all markers are original (bulbs changed with new incandescent when they have burned out She was having issues previous to my changing of the tilt away turn signal switch with the quick flash, but I'm not sure how long as her car was back burnered for some time due to us taking my G to Carlisle and Dearborn this year.
Most of my testing has been with the engine off, but I will start to look into some of your other suggestions.
Where is the ground wire for the sequencer in the trunk? I did find a plug with nothing plugged into it, but there was a ground on it that was not attached. This wire runs right beside the main harness coming into the trunk area.
Also, just in case it matters, her 69 XR-7 is a convertible.

Scott -
The auto parts store flashers are designed to flash from 60 - 120 flashes per minute, with a 50% "ON" duty cycle and typically run at about 90 flashes per minute. This means that the total "ON" time is only .33 seconds. This flash rate/ON time is too short for sequential lights because an 1157 bulb takes about .2 sec to turn on or about .6 sec total for three bulbs.

The original 1969-73 Cougar flasher (marked 4-lamp sequential trigger) was designed to operate at a slower rate with a longer "ON" time.

I developed a replacement flasher, D0WY-13350-AR, that runs at a slower rate and has a 70% "ON" time similar to the Ford flasher. It should be used for both the turn signal and emergency flasher on the 1969-73 Cougars.

http://www.ebay.com/itm/C6-1969-1970-19 ... 3a6efbdd23


Note: I've discovered that on many Ford vehicles, the emergency flasher plug is wired backwards. The red/white wire is swapped with the white/red wire. This "feature" doesn't affect the original electro-mechanical flashers but electronic flashers are polarity sensitive. The individual wire leads on the D0WY-13350-AR flasher allow the pins to be swapped if necessary.
