An alternator does NOT get harder to turn as the electrical load increases.. You F---king idi-t!


(You F---king idi-t!)?

Ok, at this juncture I have to jump in. I'm sorry but unless I don't understand what you are trying to say you are as mistaken as can be.

There is a minimum friction that has to be overcome and an minimum force that has to be overcome to move (spin) the weight of the alternator. Above these minimums the force required to spin the alternator directly increases as the (electrical) load increases. There is also an increase in force required for spinning faster but it is of comparatively little consequence. The vast majority of force needed to spin the alternator is from the power generated by the alternator. The Alternator will try to produce more and more power as required by the load, the regulator however will limit the power output so that the alternator does not overheat and destroy itself. So, there is a maximum of torque required only because of the regulator, without it the torque required will continue to increase with the load until the alternator burns up.

Now what are you trying to say?

This is where I think you guys are missing the point.

The alternator will NOT try to generate more power as the load increases. The only thing (in a car) that is going to get that alternator spinning faster is the throttle, which is controlled by the foot pedal. The throttle is adjusted for speed reasons not electrical reasons.

An example is a worn alternator belt squealing due to the increased load when you put the headlights on...
