    IIRC VS is 90A and VT is 100A.

    As you are replacing one thermo fan for two and they only cycle on and off (and switch off above 55kph), I cant see the 10A making much difference.


    Back in the 'good ole days' we found the larger amp alternators had lower output to standard ones at idle speed. Needed a few revs to get any benefit. I wonder if this is still the same?
    If I told you I was a compulsive liar, would you believe me?
