ello??? This thread is about ALTERNATORS, NOT generators!(quoted from post at 23:22:56 05/18/17) OH really?? you need to do a little research before you ask where some of us come up with such crap. If a charging system doesn't
read battery state of charge how does it regulate what current to put out???? Da!
The battery is the only thing that keeps a generator from putting out infinity voltage in a charging system that still use generators.
Just try disconnecting a battery cable sometime and you'll see who's talkin crap!!!
he voltage is the quantity being sensed by the voltage sensing coil inside the voltage regulator. That function is accomplished inside the solid state VR using a voltage comparator, comparing the alternator output voltage (which is the same as battery voltage, via common connection) to the reference voltage inside the VR. Both ultimately control the field current of alternator or generator, which in turn controls the final output. Alternator VRs do not have a current regulation function, whereas most generator VRs do have a separate current regulating function implemented by a winding of heavy wire carrying armature output current to battery & loads which opens and closes a set of contacts controlling field current. Those contacts are in series with the voltage regulating field control contacts, such that either too much current or too much voltage will cut back field current & thus output.(quoted from post at 13:43:05 05/19/17) JMOR, after this post I have nothing else to say. But I do want to ask and I hope you can explain it. If there is nothing in a
charging system that senses resistance (as you say). What causes the voltage regulator to back down on the charge??? It's monitoring
something and that something is battery state of charge. Resistance changes in a battery as it's used and as it's charged. The more
resistance is senses the higher the voltage is put out. Am I wrong???

Voltage, not resistance control.
