Missing Nut, What does it do??

Hi all,

After having spent a small fortune on my car a month ago I have had my first problem. Upon driving home the other day the injector fault warning light came on but with no obvious symptoms. I had planned to do some work on her that day anyway as my airbox needed replacing after I put a hole in the lid trying to release a siezed bolt. After replacing the airbox I was having a nose around inside the engine bay when I noticed a large cable with a washer attached to the end that was just hanging around and not attached to anything. It is located right above the oil filler cap on the side of the front rocker cover. There is a threaded bar about an inch long that sticks out the side of the rocker and the nut had not been replaced properly when I had the belts done and it ahd worked loose and come away. The fact that it is bolted directly onto a metal surface tells me that it is probably an earth of some sort. After replacing a nut securley I restarted the engine and the injector fault warning light had gone out and has stayed out ever since. In fact the only thing I have noticed since is that the clock was running a few hours behind. I reset the time and it is working fine again now.

Anyone know exactly what this cable is and what its purpose is??


Owning an Alfa is not a matter of life or death...... It's much more important than that.

without a picture to show exactly what one your on about i would have to agree with your guess that it is an earth point. sounds very much like that to me.

if its fixed the problem i would forget about it. maybe check up on it when your checking your oil (regularly i hope) to make sure its not worked loose again.
