Coach, your suspicion is test was correct. Test 3 shows a much higher fluctuating voltage measured across the Solid State Sequencer. I measure across black in and orange-green out. Test 1 and 2 showed no different. As an aside, circuit #514, (blue ex solid state) does not fully de-energise when Hzsw is on, but the voltage does reduce.

Moving to the turn signal switch, it appears that I do have the C8WY-13A366, and the C8SZ-13A366A (picture attached). The single barrel flasher has been spliced into the circuit #459 (Orange-Green) circuit, and sits between an Orange-Green and Black-Green wire.

From the photo, a couple of things seem odd.

1. a black ground wire which goes no-where,
2. a blue-red wire which goes no-where
3. a yellow which goes onto a relay/fuse (?), but nothing coming out.
4. a contact on the back side of a what I think is the flasher unit, which is not being used.

I suspect the barrel flasher was put in due to a fault on C8WY-13A366, or C8SZ-13A366A. Any suggestions on where to go from here would be greatly appreciated.

After a bit more fiddling I have established that the flasher unit C8WY-13A366 is working on the Hazards, but I have no idea what the two units in Q1 in the second picture are. The bluse-red wire is coming out of the fuse unit.

AJ,

Unfortunately, the PO did a hack job on the wiring harness. I am guessing that the PO spliced in the emergency flasher can because the original Sequential Motor did not work. In any case, switching to a Solid State Sequencer should have solved the problem however with the wiring hacked up, you will have to do some electrical tracing.

Is your Cougar an XR7 or a standard? Does it have a tilt/swing away steering column? Do the headlights and interior lights work? Are there any other non-factory wiring splices that you can see?

I would definitely trace the wires from the Turn Signal Switch to the K7 relay and from the K7 relay back to the Sequencer. I suspect that the flasher barrell is spliced in somewhere between these wires.

Good Luck

I re-read your post and you do point out that the flasher can is spliced between #459 ( output of K7, input to Sequential ) and a green - black wire.

Trace the green black wire as it should eventually splice back to the Orange - Green wire , unless the PO pulled a new green - black wire all the way back to the Sequencer. If you verify that this is the case, remove the flasher barrell, and (do I dare say this!) splice the wires together.

Remember on a 67 and 68 Cougar, the Sequential motor provides the flashing of the center hazard lights as well as sequencing the taillights. This is why they do not have flasher barrells.

Success. You were dead right, I removed the flasher barrell, connected the two wires and the indicators sequence !!. A thing of beauty. Thank you, thank you.

Its a XR7.

Hey kid,

The pdf file is 29 pages long so I don't think you'll want to read it on your phone.

OK so I put power to K10 and started the car the hazards blink slowly, going to the turn signals the dash indacators still both illuminate but now there is steady out side rear light blinking with intermittent middle light blinking in sequence, never the inside light.
