Title: FC blinker wiring Post by: lucky_gwen on December 28, 2008, 02:30:30 PM The original 3 pin flasher has been changed to a 2 pin flasher and we cant seem to get them working. The wiring is a nightmare. We can get them to blink manually but for some reason they wont work with the blinker shift.
Any help would be appreciated as my rego inspection runs out on January 4 and the blinkers are the only things that need fixing. Thanks Janette Title: Re: FC blinker wiring Post by: mcl1959 on December 28, 2008, 04:49:27 PM Janette, without being able to look at the car and trace wiring, it is virtually impossible to diagnose. If it were mine I would remove the wiring and reinstall as per the manual with a 3 pin flasher. The FC blinker stick mechanism has been built in such a way that the flashers operate through the tail lights, if you don't have an FC column then I would wire the blinkers as per the manual for the car that the column comes out of.
Perhaps if you could advise what column you have and what blinker mechanism and where the rear flashers are (tail light or below) then we could help some more.

We will pull hte one off the spare FC out the front and fit it. The car now has an FC steering column.
Hopefully once we change the blinker harness they will work. Cheers Janette Title: Re: FC blinker wiring Post by: lucky_gwen on December 29, 2008, 01:39:56 PM Well we re-wired the other blinker harness.
The front blinkers work perfectly. But the back blinkers both blink together. Any suggestions???

Ken Title: Re: FC blinker wiring Post by: lucky_gwen on December 29, 2008, 09:54:56 PM Checked the earthing and all is well.
Very frustrating. Might have to take it to an electrician to have a look at it. Anyone from Canberra know a cheap electrician???? Or anyone from Canberra know anything about electrical wiring??? Cheers Janette Title: Re: FC blinker wiring Post by: ridgey_didge on December 30, 2008, 10:06:44 AM Janette,
I don't know about cheap, because I have only used him for a trailer connection, but the guy under the old servo at Jamison often has old cars in his bays. He may be interested in looking at it, whereas some places just won't touch old cars. Give him a call and get a quote maybe. Good luck David Title: Re: FC blinker wiring Post by: brett_f on December 30, 2008, 11:28:19 AM Jannet,
Just a long shot as it could be anything. Do both the rear globes have twin terminals? Do both globe holders have twin inner terminals to suit a twin terminal globe? Hope this helps. Regards brett Title: Re: FC blinker wiring Post by: mcl1959 on December 30, 2008, 08:42:20 PM Janette - if earths are both good, then go right back to the wires coming out of the column. The pink and viloet are the 2 rear indicator wires. Attach a test lamp directly and test each one separately.
If no good unhook the white wire from the column and test again. This is the brake light override. If still no good & the fronts work perfectly and the tell tales work perfectly then I would assume the switch is faulty. Basically with electrical problems, keep going further back in the circuit until you have isolated everything. Ken Title: Re: FC blinker wiring Post by: lucky_gwen on December 31, 2008, 03:18:34 PM Thanks for you help
We tested both pink and violet with a test lamp and the lamp blinked on both colours. Unhooked the white wire and the test lamp still blinked on both colours. Brake lights didn't work. What are the 'tell tales' exactly??? And what switch are you talking about. Janette Title: Re: FC blinker wiring Post by: RET on December 31, 2008, 05:56:09 PM Tell tales = little green arrows on the dash to tell you the blinkers are, well, blinking.
If both rear bulbs are flashing then it sounds like the left and right brake light circuits have been bridged somewhere. If you have a look in the electrical section of the Workshop Manual there is a very clear explanation of the switch (behind the steering wheel, at the other end of the blinker stalk), and how the various combinations of left/right with/without brakes should light/flash the rear lights. Hope that helps. cheers RET Title: Re: FC blinker wiring Post by: mcl1959 on December 31, 2008, 07:07:16 PM As RET has said. You have now eliminated faults through the wiring into the rear of the car and the brake lights as well. (Unhooking the white wire will stop the brake lights working but also checks to make sure something in the brake circuit is not affecting the blinkers). The next step is to replace the switch (you need to remove the steering wheel to get it out). This should be tested first by obtaining a spare, not installing it, but just hooking it up to the wires in your car and operating it on the floor of the car.
If you can get the indicators to work correctly with another switch then you would go ahead and replace it. Ken ps - if it turns out that the switch is faulty, don't remove it before getting instructions about what not to do.
