I started out with a small case 100 amp "one wire" alternator because just like you, I figured no A/C, no power windows, no stereo, how much power could I need?
Problem is that when I drive to work it's always dark and usually cold, so I'm at least running lights, heater, and radiator fan. Every time I stopped at a red light,(there are 27 of them on a 33 mile one-way commute), the one-wire alternator fell off line. It seems one-wires don't really put out rated voltage below about 1800 rpm.
After I drained the battery at an autocross one day I decided the one-wire had to go. I now have a Ford 3G 150 amp and couldn't be happier. If I need to shave off that extra 3 pounds, I'll skip lunch for a week.
