Replacing the bearings, brushes and testing the rotor/stator/diodes/supressor are inside of the power of the normal VW operator but I would go away substitute of your slip rings to some rebuilding store Unless of course you've got a large obligation soldering iron and you have found the Procedure executed a number of instances.
Some voltage regulators works by using this like a reference to manage the alternator output. Frequently the brushes (and the rotor field) are powered via a different list of diodes. Delco alternators have this type of list of diodes, termed a TRIODE ASSEMBLY: it's three diodes in one
