Posted by John Fletcher on December 18, 2019, 8:33 am

Year of Manufacture: 2012
( Optional ) Engine Code or CC: 1400

Alternator charging at 13.1 volts I normally fit Ford units to these but there wasn't any available and they were £340 +vat I fitted a lucas unit from ECP it lasted 6 weeks when I phoned to say it was faulty they said it should never have been supplied to the vehicle I phoned another supplier who said they had one for the vehicle in Delco Remy that was the same 13.1 vols I phoned the tech dept and they told me it was the correct alternator and it must be faulty I fitted another unit and that was just the same having only ever fitted Ford units as anyone else had problems with aftermarket on fords Cheers John

I haven't had any problems but could it be something In the pcm strategy like a temp sensor making it have a slightly lower voltage?
Will it charge with the plug disconnected?

have you checked the connection to the battery sensor on the negative battery terminal?

Hi
I take it that is 13.1 at alternator as well a battery ? i.e. no voltage drops

some of these smart charge systems read low voltage at times depending on conditions /strategy of ECU,what is the actual symptoms with the vehicle ?
Any Fault codes ?
