great think weve solved this one then
,think its 14.4 but check with saint v8 hell give exact figures,alternater is costly and a bit naughty to access and remove
The general consensus is around 14.2V.....
There is a hidden menu on the L322 that can bring up a system read voltage at the battery, but I have concern on its accuracy as I have seen mine and it reads 13.8V most of the time, momentarily dipping to 13.2V when i switch something on and then going back to 13.8V once the Alternator regulator picks up the slack....so the reading could be off by around 15% or so!!
I will run my engine later and measure across the battery terminals as getting to the Alternator is a pain! But I am sure Alternator output directly is around the 14.2V mark, with volt drop to the battery which is why the reading is lower than Alternator Output.
Hidden Menu Procedure:
Ignition key must be “off”.
• Press and hold the Check Control button in the instrument cluster (RIGHT button), and turn the ignition key to the first position (KLR).
- You will first see "Check Control OK", some seconds later you will see "Test Nr.01"
- Push the left button on the instrument cluster to see the car's identification number. Add the 5 digits (not 6) together and write down that number, you will need it for unlocking all the functions. Example: A123457 will lead to 2+3+4+5+7 = 21
- Push the right button until you see "Test Nr.19"
- Push left button until you see the number that is equal to the one you calculated above
- Push right button again
