Help Please - Where should this wire be?
My battery light is on so, although I know not what I am doing I have just checked the voltage, engine on and off. It remains at 12v so I guess the alternator is screwed!
Anyway....I have just noticed this loose wire coming off the loom that goes to the FBH and wondering if anyone knows where it is supposed to be attached......????

I have just had my alternator changed. It started with a HDC failure in the morning, every time I started up. Finally it was preceded by a full house of failures, strangely none of which mentioned the battery.

I have a dangling front brake pad sensor wire, taped up.
My battery light couldn't be some strange electrical feedback because of this could it????nil admirari

If your battery light is on I would say its the alternator you should look at.
The brake pad sensor wire will have nothing to do with the alternator/battery warning light and your battery voltage should be between 13.8V and 14.8v with the engine running therfore alternator knackered

Thanks Ian...car now in with local garage to change alternator.
Sorry to ask again, but would anyone mind just popping out and looking under their bonnet to see where this wire should be attached?

If you mean the black sleeved wire on the left - on mine it plugs in to what appears to be a temperature or pressure sensor on one of the air-con pipes running alongside the battery box.Clive

if it's a black/red and black pair cable going to the connector then on mine it just sits in a holder attached to the loom and isn't connected to anything:

Only cable on mine that is attached to the FBH harness goes to a sensor on the aircon line at the left side of the battery box. No other cables present other than the three that plug into the FBH.

I have loose one near the FBH too; not connected to anything and just flaps about. I would have posted about it years ago but the whole 'inserting image' thing would have defeated me!

The blanking end clips into a plastic bracket on one of the other wires. Not connected.

the wire in your photo was connected to the transportation relay when your vehicle left the factory and on pdi this relay is removed and the connector is fitted toi the blanking cap, this will have nothing to do with your electrical failure.
i think your alternator has failed!! replace it and trickle charge your battery overnight and your gremlins should disappear.....

As a matter of interest, are there any more of these transportation plugs or relays?
