Dear all,
do I really have to change my alternator?
Today my Jag showed the battery warning lamp with "Battery is not charging".
My batteries are 2 years old. This fault is shown the first time.
The big one had 11.9 V to 12.2 V while the engine was running or not. I checked the current. Even with the engine running
the Jag is discharging the big batterie (battery 1). Battery 2 is charged while the enginge is running. But the voltage
is too low. Under 14.0 V.
I should measure min 14 V from the enginge block to battery 1 plus pole while the engine is running. Right?
If not, the alternator is broken. Right?
Please tell me something like "It is only a broken fuse of the headlamp"

Have a nice evening
