Dave, I should have answered about the regulator assembly brand, but your answer is the same as mine; I know the Bosch and don't know the aftermarket brands. Can't possibly say which is "better" even after repairing dozens of Bosch alternators, because I've never bought one new. Always, I've had spares from the junkyard, and those I've chosen to put new brushes in for spare regulator assemblies have been Bosch EL.






















And yet, it went without saying for me, to get bright light or at least a pinky finger on those slip rings. The alternators put into our cars are now at an age replacement slip rings might be past due.
