All the lights in the unit have stopped working except the indicator which is very faint. Side indicator also not working.
It’s suggested that this is a bad earth to the whole unit. Maybe on the chassis rail below. Requires wheel off to access or possibly lower engine cover removal.
Does anyone have any more knowledge?
Thanks Steve

Going solely from the electrical diagrams and without an X150 to help, this is the best I can offer , but it may help guide you anyway

First pic shows all the ground wires for the left hand headlight, the second for the right and the third is an extract of the list of ground points, where they are and the various ground wires that share each ground point, but it's only the location that you need. The reference to Junction Box is in the column titled 'Harness' but that doesn't mean much to me without a car to look at!

Can't seem to add pics by editing, but here's a couple more to assist I hope

Thanks for the diagrams. They agree with a picture sent by someone else. I took it to Autoclassico with all the info and they fixed it for 1 hours labour. Seems the stud had snapped off. They found another bolt and fixed it nearby. Steve

Hi Steve,
Glad they found the problem and got it fixed for you.
Take care.
Andy
