Hi all had a new alternator fitted about 4-5 mth ago ive just checked the output due to lazy starting and i have changed battery and starter motor but the alternator is putting out 13.3 to 13.4 volts is this right as i checked the wifes volvo and that puts out 14.2 to 14.5 thats where i thought all 12v cars had to charge around that sort of numbers thanks guys

your year WM says 14.5v... ... - .- -.

The alternator output varies according to the charge level of the battery and the equipment running on the car.
13.3-4V is way too low and indicates a fault.
My own Td6 generally runs at 14.1 or 14.2V and has done for years and keeps the battery fully charged.
If you have a set of jump leads try connecting from the engine block somewhere to the earth jump stud on top of the strut mount and see if there is any improvement for a start.

Thanks guys i thought it was too low that not enough to charge a battery of that size where abouts are the engine to body earth lead (s) on the td6 i will try the jump lead trick though that worked on one of my old cars few years ago

I have been having battery issues recently and can confirm that at normal tickover the alternator output is 14.1v / 14.2v .
Battery drain with everything off after 30 mins on my car was 35mah, well within the 50mah max suggested in test manuals. 2007 TDV8 VSE

What was causing your drain issue mate

Sorry I must have not been clear, Car tested fine but for reference Alternator pumping out 14.1, 14.22v. Drain test after sitting for 30 mins 35mah. New battery and all is well

Could it be possible that my new battery has failed or failing all ready

it does sound like the alternator is not putting out the correct voltage...i'd have it checked out.. ... - .- -.

Am i right in saying there is 2 types of alternator for it one that has 3 pins and one has 2 pins on the black plug connector

Thanks all for the help ive done my td6 today found the engine earth on the aircon pump all with molten metal from the bolt around it so took that off cleaned up new bolts and a fitted a extra earth from the strut top to the back of power steering pump fired car up and now charging at 14.2 and with lights and blower on full blast it charges at 13.9 to 14.0 volts hopefully all is well now

Amazing how many times an old earth strap causes problems.
That's why I always fit a supplementary earth strap to any car I buy as a matter of course.

thanks for the update on the fix, always good to hear the outcome 2007 TDV8 VSE
