How is your ALT led on the dash behaving?
The instrument cluster is a critical part of the Vanagon charging
system. It provides the voltage to the field winding of the alternator
to get charging started. It does this over the blue wire that is also
used to indicate charging status. The alternator needs the instrument
cluster to be there and working to some extent.
