hi new to the forum,you've probably been asked a thousand times before?
i have a corsa b 1.7 diesel (Isuzu) battery going flat after a few days,checked for charge with multi meter,only showing 12.6v when running,so i presume its not charging enough?,but battery light goes out once started and stays off.
when switch ignition on,battery light flickers a bit,and a clicking from drivers side kick panel,i presume this has a relay inside,should i change just the relay?,or will it be the alternator at fault as well?,thanks for any help

Your problem is likely to be an alternator fault, but before you go any further, make a temporary connection between the main alternator terminal and the battery POSITIVE (+) terminal and re test with your multi-meter -You should be getting about 14 Volts.

If there is no improvement, link the small alternator terminal to the main terminal and again re-test. If still no improvement, the alternator needs either replacing or repairing.

Regards.
