As for the not charging at Idle?

A lot of Patrols fitted with RB30's ran a Bosch alternator & thay are renown for low charge rates at Idle so I would not be overly concerned by that fact if your alternator is Bosch of course.
if i replace the alternator will that come with the regulator???
as for the testing well the service at battery world was pretty poor and did not seem to want to help. also the alternator pully bearing sounds as if it is on its way out so if i can kill the 2 birds with one stone so to speak than that would be one piece of good news for the week
