I once it is running check to see what the voltage is at the battery, should be around 14 volts ( 14.4 volts in a perfect world, LOL). If it is lower than that, and you hear it whining then I would change the alt. I have had to change mine twice in the year it has been on the road.
I agree, 10 minute job and not get dirty either, well maybe some salt on your clothes if you live somewhere that uses it on the roads, LOL. It is real simple, I even showed my FiancÚ how to change it if she really had to.
