old DC car generators had heavy brushes, and worn out frequently
car alternators have 3 phase windings, 3 outputs of AC electricity that is rectified internally by 6 diodes to make a smoother DC.
those diodes create a lot of heat, the internal voltage regulator compensates by reducing the power output, to keep the alternator working
connecting directly to windings feeding those diodes, bring that high frequency AC power to a set of external diodes, use the external diodes to rectify the power to charge the RV house batteries
reduces the heat load on the internal alternator diodes and windings
you get a longer life for the alternator, and more power higher charging voltage into the house batteries
