Have you checked the earths at the actual bulb holders? If it's anything like the equivalent Pug the earth is rubbish and needs fortifying. A little extra check here can be looking at the rear blinkers; if they're weak then you have a problem with earthing.

Also test for voltage at the taillight assembly main plugs.

Check the brake light switch attached to the brake pedal under the dashboard. It is a little white sensor with a threaded body that is screwed into a small bracket. Had a similar issue with my car, replaced the switch and the lights worked again.

To check if it is faulty, pull off the connector and get someone to stand behind the car. Get a wire and bridge the connector, if the lights turn on, it is a faulty switch. If not, it could be a relay as you mentioned. I do not know where that relay is. It could also be a fuse, but you probably have checked that already.

You could have cleaned the switch contacts using carby cleaner and grey Scotchbrite after dismantling, and saved some coin... 

Bazz may have an opinion on "contact enhancers" such as Stabilant-22A but I've friends who swear by it when used correctly.

Thank for the help guys, i will check it out today 
cheers shane

Ps his anyone used LED globs for tail light ?

[V AR 164]

No I only use standard globes for the tailights. The LED versions can be pretty pricey and I don't see the need for it. Maybe on the number plate, a white LED will be good, but the stop lights aren't really necessary.

I have just got some LED'S globes for $10. in white
I have try two earth wires and cleaning the contacts with no success 

cheers Shane

The white LED bulbs will make your lights look a little orange when it is passed through the red lens. Better to use red LED bulbs for this purpose and save white LED bulbs for reverse and number plate lights.

Also, perhaps best not to use LED bulbs till you know the system is working first. They aren't always a plug and play system due to polarity and other possible issues. Also, they will possibly throw an error on your ARC as the system will be expecting greater load. Can be rectified with the correct resistor.

Get the multimeter out and follow the trail. At some point you will find an irregularity.

Thank you for all the great ideas, I am going to stick with the old globes.
Today did as Andrew said and took out my brake switch (see photos) I did find a burnt contact on one side.
But it still not working not shore were to look next ?
cheers Shane

Yeah it should work perfectly fine

[ARQ164 Shane]

so today i put in the second switch with no joy  so as people have suggested i will look at the ARC

cheers guy, always having fun

Find attached fault finding and troubleshooting extract that may assist in sorting out the brake light problem.

I have on the alfabb talking to Steve and this is what he seed guys.

OK finally got into 164 Euro wiring diagrams on cardisc.com 164 DVD. stop light wiring diagram on page 32 and very simple compared to our USA spec 164 wiring diagram.

I can't scan it for you because my scanner/printer in FL house now. My old printer I have here does not scan documents to pdf file.

Any how power from battery power goes to 10A Fuse F15 in main fuse box G1 and then to H3 brake switch in a white-yellow to white wire at pin 1 of switch at brake pedal.

Check for 12v at white wire.
Jumper white wire to white-red white at pin 2 of switch and see if brake lights work.

It appears Euro system does not have I-69 relay nor does it go through N22 ARCU. However, the white-red wire from H3 brake switch does go to C10 instrument cluster connector Ci pin 6. Then red wires from cluster connector Cii pins 3 and 7 go to L/R tail light brake light bulbs.

So I'm going to give it a go, I will let you guys know what happens
cheers and drive safe

thanks Bonno
I will use your pages too, thank mate
