    Default alternator question

    hey guys,
    just wondering if anyone knows the typical IDLE output of the oem 105A alternators, im just trying to settle my brain on this and cant find the info! is the idle 105 or is that the max?
    mine is a delphi and the only things i could legibly read are

    104803SSW 105A
    31501...
    some of those numbers may be wrong but kinda close i guess

    i cant find anything on this alternator...
    thanks!

    No idea on the numerical rating, but the subjective rating is, IMHO, 'not enough'.

    I can not tell you the exact idle output of your alt; I can however, tell you that most factory units produce about 50% of the rated output at idle.
    A high performance alt might produce up to 70% of the rated output.
