OK my car is a Car is a 93 r33 gtst, rb25det,
i went for a drive early this morning and when i came home i noticed a kind of juusssh juusssh noise almost like a belt rubbing or a kind of grindy bearing noise coming from the alternator.
The noise fades away (almost to nothing, very faint) when i turn off my lights and gets louder when lights are on and louder again with high beams on (low beam stays on with high beam) .
My voltages are 12.8 car off and 14.3 running on the PFC
Just wondering what peoples thoughts are, Is my alternator on its way out? Everything seams to work fine still?
