The power required to spin the alternator is directly proportional to the load placed on it. One of the most enlightening (no pun intended) science demonstrations I participated in as a kid was spinning a hand-cranked generator while various loads were applied to it. No load, easy to turn. Flip on a single 60w light bulb and it gets hard to turn. Turn on 3 x 60w lightbulbs and you can't even turn the crank there is so much resistance. Your engine experiences the same thing when you apply electrical loads to the alternator.

A 90amp alternator can output 1,125 watts at 12.5 v.
Even at 100% efficiency that would require 1.5hp off the crank. (I don't know how efficient automotive alternators are, but it's not 100%)



very well put, but.....are the newer equipment(ALTENATOR and FANS) more efficent, because they have better designed bearings etc- better manufacturing than 30 years ago?

in the race world- some people even use electric waterpumps instead of crankshaft driven ones.
