The Bosch would be the one with the replaceable regulator but I do not have that one (I ordered a regulator thinking I had the Bosch). Also, this is intermittent so I am wondering if anyone has found bad crimped connectors where they attach to the alternator - I went through this awhile back, pulled the alternator and had it check at a rebuild shop, then the problem went away for awhile. Will a Bosch fit in place of this one in case I need to replace the alternator?
