So, just finished the refurb on my 72, every was running fine, started like dream every time... Jacked up the front to put the number plate on, bus has been lowered... Then all of a sudden just won't start... nothing..Zip!!! Starter motor won't turn over, I've given it a wack to see if stuck but nothing, battery light comes on fine, 12.6v's running on the battery?? any ideas??? got me baffled.. Cheers
