This is a hard question to word so please bare with me. An alternator is always spinning and driven by the serpintine system. Does the load change on the crank/serpintine system when there is a draw from the electrical system? Or does the load remain constant, and the out put regulated by a controller or something.
Let me know if I need to clarify. |

I don't think the load changes, if it does, it may be minimal.
If you draw more than the alternator can put out, you'll just burn out the alternator.
I could be wrong, but that is what makes sense to me :) |

| The load will change, i have tested the out put of some alt, when the unit was load tested it stalled the engine, the engine was no big but your load will change. The voltage regulater is in charge of this. |

| voltage regulator controls the amplitude of the magnetic field of the rotor. this controls the load. if it was loaded at all times you would have to much voltage and lights would start popping and other bad shit. |

That's an odd thing. On my 2.0L motor, it I used the stock 90 amp alternator to run a huge stereo.
I was probably pulling a bit more than it could supply, the light would dim if I turned it up, never stalled it. I'm sure if I turned it up full for a sustained amount of time, it would've drained the battery and pulled all the power from the vehicles electrical system, and THEN stalling the car.
The alternator would never stall the car due to the "turning resistance" of the alternator that the motor see's which is what I think Xtra_X is getting at.
There's a company on the south that will rewire an alternator for higher output for far less than it would cost to purchase a high output alternator. |
