Thanks all for the feedback, looks as if it is the starter. Probebly the solinoid contacts which I bet you cannot get to. Wanted to know if any other series4 Aero's have had this problem. Had the wing off today and had a look, looks as if it is a garage job as it seems as if you nead to remove the exhaust manifold for access (you cannot even see all the manifold bolts) its so cramped in there.
