Another area that little is paid attention to is the ground. You must also improve the ground as well. A poor ground will hinder the alternators ability to send power to the battery and can burn an alternator up just as fast as an inadequate alternator to battery wire. Your ground may be fine when you first install your alternator but over time corrosion and resistance builds up in the ground connections.
If the battery is bad, then you should replace it....because the battery is bad. Not because you replaced the alternator. If your battery is good, and you want to play it safe, charge the battery before running it with the good alternator. Or just let the alternator charge the battery. I agree with Unclebob, but it depends on the alternator.
