Help! 2 wire Alt convertion question?

The voltage regulator regulates just that, voltage. by regulating the voltage to the rotor through the slip rings you reduce the magnetic field strength and that lowers your output voltage. the amount of amps is produced by the rotor spinning faster pushing the power through the stator. thats why when you buy an alt. upgrade kit the main two pieces they come with is a wider stator and diodes (the diodes to handle the added amps.) as long as you upgrade the charge wire you could put a 100 or more amp alt. on an old single field regulator. the "load" does not pass through the regulator. it only senses the output voltage and adjust to apply more voltage when the system demands more and that causes a voltage drop. thats why you don't see aftermarket regulators claiming higher amps. the amp load is handled by the alt. not the voltage regulator. single or dual field they do the same thing just in a different way.
