I have a VS V8 showing all the classic symptoms of a voltage regulator on the way out. Warning light flickers periodically (i.e. total 15 seconds over the period of a 40 minute trip to work) and all terminals & connections appear tight. Alternator appears to be putting out sufficient voltage (except for when the regulator is playing up which is never when I'm testing it!!). I have bought a new Bosch regulator & brush assembly and I was wondering if it is necessary to completely remove the alternator to replace the regulator? Or can the regulator be removed and replaced without removing the alternator? I found one old thread on this forum with tips from Guy and Garth about removing the alternator and placing the alternator on its pulley to stop the commutator(?) moving. But I don't know if that was a V6 that had to have the alternator removed (maybe clearance problems near the regulator?) Haynes manual (piece of crap) is no help as it only refers to it in the overhaul procedure with the alternator already removed. Any advice and tips would be much appreciated. Mark.
