Alternator not charging
Hi guys,



After fixing the cooling system, the power steering and the ABC suspension are OK.



Now, I have a problem with the alternator not charging. DAS says:



CODE 1337: Alternator serial interface.



Nothing else so far.



Any ideas? (What a summer!)

Your car having problem with alternator, you might change alternator regulator and if it not fix then you need to change a whole alternator.

Here are the screens from Xentry. A bit strange, aren’t they?

Replace alternator regulator first, if the isue not fix then you need to replace alternator.
