Ford Kuga.intermittent Charge Problem

[Michael50]

Hi

I have a Kuga 2009 of which had a charging problem so the garage decided to change the battery but it still has the same fault.I decided to moniotor the charging circuit ann sometimes it rises to 14.2v and sometimes it goes down to 11.5v of which then if i switch of the engine and switch it on again it usally does not start unless you jump start the car.It is really annoying because it is intermittent and i wonder if anyone else has had this problem.I have resarch the website and other websites but most people highnlight either the alternator or the ECU.See attched Pictures

Thanks

Michael
