Hi guys
just had a phone call from mechanic and hes just fitted a new alternator and its only charging 12.5 now when the reason for the new one was because the old one was only charging 13.5 hes mentioned a smart charge does anybody know what this is or the answer to my problem is ...i have a battery light on which has made me go for new alternator.

Later vehicles (i.e. from 10MY) have a "smart" charging system and do run at lower voltages, but yours shouldn't be. What type of aternator is it; is it OE? Visiting from DISCO3.CO.UK

No i have just had a denso 14v 150a fitted which is the replica of the previous alternator.
any idears would be appriciated mate

Denso is OE so no issues there (thought, that's not to say it can't still be faulty).

Have they checked the control connections? Visiting from DISCO3.CO.UK

I have a guys number who is an electrical mechanic so hopefully when i can get through to him he will be able to test the connection as sadly im not very electrically minded.
would you say that with my model and year i would have this smart charge thing then or if not what could possibly be the problem as ive now had a new battery and new alternator?

No, you don't have the smart charging system. I would think the problem is likely to be either a wiring issue or a faulty alternator. One would hope it's the former, but faulty parts out of the box do occur...

Ive now got it booked in tomorow at a garage that "specialise" in electrical faults he said it could be the wire at fault . Also ive taken the old alternator to the local shop where they recon alternators and hes told me its definatly got smart charge on it as i have the smart charge connection on the alternator so now im very confused :/ .

Ive attached a photo of the old one when it was on if its any help. Cheers for your help on this much appriciated

The alternator is not entirely dumb, it is controlled by the engine ECU, but the true smart charging system with battery monitoring etc. is only on the later vehicles.  Visiting from DISCO3.CO.UK
