You shouldn't have any problems upgrading to a alternator of that size. You might ask the guy that i posted below and see what he says. He knows his shoot about alternators.

When i had my old 2002 silverado I bought a alternator from a member on another forum that was a 270 amp alternator. I was running e-fans, 2 electric compressors and someother misc items and I didn't have a minutes of trouble.

here is a link to his profile from another forum.

Tell him Jonathan told you about him and he will take great care of you.

for a 100a you won't have a single problem, take the old one out, put the new one in and make all the connections. I reccomend a 4 ga or heavier cable be added from the output post to the battery, and it shouldn't need to be fused, no longer than that cable would need to be, as long as its not rubbing against anything metal.
