Thanks Guys
We’re on the same page chaps- I’ve decided to take the car off the road whilst I’m home and tackle all the outstanding jobs and the new ones I’ve come across like rocker cover gaskets and I think a power steering fluid leak. The MOT is due in July it has a raft of advisory’s that I should address.
But I do think I can round off this thread by saying “yes” my battery was as all signs indicated- defective.
Battery has now been replaced- going to have a poke about tomorrow and see if I can figure out why it cut out in the first place: Will update that in my original thread
Thanks Guys
