battery light comes on and off. rectifier? part# needed 96 sc400
The car is a 1996 Lexus SC400. I need the part number for the alternator rectifier (not the regulator). My battery light comes on and off during driving. The electrical systems loses power. I put a full charge on the battery and checked the connections. The problem persists.I will be changing the brush set for good measure when I remove the alternator along with checking for oil spillage from the above power steering unit. It seeems my alternator is phasing in and out where it seems to work sometimes then the light comes back on and the battery gets drained. Is this a typical symptom of a bad rectifier? Thanks gents.

alternator phasing in and out - a new brush set solved it!
No rectifier needed. It turned out to be a brush that was worn. I replaced it with a $10 ebay alternator 
brush set and it solved the problem. Sure beats whatever the Lexus dealer would have charged. I hope this helps someone else out as well. For comparative purposes, the car has 143k on the odometer at the moment.
