Well, I've done a search on this and have determined that it's either the alternator dying or it's a dodgy earth, perhaps the big one that goes from the battery tray to the gearbox.

Would it be fair to say that it's more likely to be earth issues though?

Symptoms are as follows:
  • Light isn't filckering all the time
    Generally isn't on at idle when it is flickering
    Flicker is intermittent, weak and then stronger at times - at times cutting the ignition while driving so it's stuttering (this is the main thing that makes me think it's the earth)


If it is earth, is there a guide to where they all are? I don't fancy tracing all the wires round the nightmare of an engine bay lol

Thank you all very much in advance for any help! :D
