Hey everyone, today I’m going to show you how to replace the alternator rectifier and brush holder on a Honda S2000. Today, I’m replacing the alternator rectifier so that I can fix the common flickering instrument cluster issue that I described in a previous video. I also decided to replace the brush holder while I was at it. Lets get to it.
