No problem. I'm not an electrical guru but isn't the rebuild kit pretty much returning your alternator to "like new condition"? Which means it will still only output the current it was rated at? With all of those electrical components I'd look into a higher output alternator instead of rebuilding the one you have.

x2. check out power master alternators, i've had good luck with them on my stuff- price isn't bad either.

You can check auto parts stores around you. They have alternators for about $120. It is not $35 but they do come with a warranty. You can always give it a shot though. Worst that happens is you are right back where you were and $35 lighter.
