I've thought about this alternator issue for a while, did couple of tests at idle and with alternator shut off ( not charging), my load at idle went from 17% to 16%, not much, but it's something. The thing that I would do is I would not recomend taking the alternator off completely, but put a switch on the regulator so it would turn the alternator on when it gets bellow set voltage and whenever the brake pedal is on ( hook it up to stop light switch), another thing is why can't we take out the 12.5v battery and install 14v battery? you would keep 14v with alternator off.
