****ed my electrics, well the ignition live, is it fused???

Post by Russboy » Wed Jul 09, 2008 6:43 pm

Basically I’ve hard wired in my road angel today, which ironically is now working!

I was going to wire off on an ignition live, black and yellow in colour that is quite a common wire on the fusebox as it is the switchable live feed to the wipers, indicators etc. I also wired my reversing camera off of it via the tailgate when I bought the car.

Not entirely sure how I’ve done it but now with the ignition on there is no power feed to this wire, meaning no indicators, wipers etc.

The car generally is ok; it’s just the ancillary electrics that are failing.

Anyone had experience in this area, or am I going to have to go to Audi who will no doubt charge me a fortune, when I suspect that somewhere in the car it should be fused, shouldn’t it?

If it is fused at all, anyone know where?

Checked ever fuse in the fuse box, all fine, but my thinking it is further back in the power distribution network. Had a nose up in the dashboard and there are further fuses, such as 50 and 60amp ones, all seem ok. There also some that are in a metal box as such so you cant tell if they are blown on not.

Really not wanting to take it to Audi when I think (hope!!) it should be a simple fix, just need someone with the knowledge on how to go about it really,

Cheers,

Russ

the main switched feed is the x75 yellow terminal closest to stereo under steering column ... Is this still getting power? Which cable did you actually splice into? and reverse should have a feed from ignition and also feed from reverse light cable to cam sensor on headunit.

Can you hear the relays click when you turn the key also?

Had the lower dash off, and been looking at the larger fuses away from the main fuse box, such as the 50 & 60 amp fuses, all seem ok.

Camera I wired into ignition live as using my pioneer Avic X1r you can actually use the camera whilst going forwards, helps keep an eye on the people you've just wasted!

I'll take a few pics tomorrow, suspect I know where there is no power, but there should be.

Just to clarify one turn 1 of the key the radio etc works, turn 2 just produces the dash lights, so it's the turn 2 live feed from the ignition that is breaking down somewhere.

In my bones I know its a simple fix, the fecker will be diagnosing it!!

Now been told to look for a relay with 18 on the front as it controls indicators, wipers etc, sound any good?

Pretty much stripped all the steering column and lower dash out. Now found a relay that is receiving and ignition live but not sending one back out. However when I trip it by manually making the connection on the relay (I took the cover off for a nose) everything then fires up.

Have a mate who works for Audi bringing one down this afternoon, fingers crossed!
