What is this wire for

[ras4x4]

Hi all I have had my 02 d22 for 4 months now with no problems but when I was under the bonnet this morning I notice the black wire with yellow stripe that is connected at the back of the alternator but the other end near the air filter isn't connected to any thing should it be?

Mate. At a guess it looks like an earth wire. There should be a connection point for it on the body work there some ether. It should DEFINITELY be connected to something.

If it is the same as my Nav (it's hard to tell as mine is all covered in mud) it is connected to a bolt on the top of the radiator support thing that runs across the front of the engine bay at the top, just between the rubber bonnet stopper and the end of the bonnet support arm.

Mount it to any solid piece of metal in the car, should be fine... (just remove a bolt that is within reach, and stick it under that).
