I have a 72 with AC.  I knew the alternator was not origional, but I just noticed it is 42 amp.

I know with AC it should be a 61 amp alternator, what implications are there with using a lower amperage alternator?  My AC doesn't blow very cold, I don't think that has anything to do with the alternator - does it?

Thanks,

Matt

The alternator rating will not affect the A/C at all, unless the battery is going low.
 
My car has A/C and the 42 amp alt.  I don't know if it is the original alt.  I don't think it is.

As long as your battery gets fully charged, you are fine.
