[oil pan 4]

I took my old alt apart.
I can completely reengineer this thing.
Convert the stator windings from 3 wire to 4 wire wye. I can see where the wires come together and I can access them.
Whats the difference between 3 and 4 wire? By adding a current carrying neutral wire I can increase stator capacity by about 70%. Decrease the working load on the line diodes.

Then add a PWM controller or resistor to the Vreg power source to slow the charging rate if I want to.

Add a pot to the Vsense terminal to turn up the volts if I so desire. On the big old generators which had a voltage reg not so unlike this one they typically used 0 to 50 ohm pots to fine adjust the voltage.
So I figure stick with what works and get a 0 to 50 ohm pot to put on there.

The wires that make up the stator are 16 or 18 gauge, so there is no way each wire is holding 100+ amps RMS. Those wires would just melt.
20 or 30 amps per line max (if it were to stay a 3 wire).

I ordered 25 of those Texas instruments Schottky diodes. $90 after shipping and sales tax.
All I can do is give it a try.
There might be a few other projects I can try them on so I ordered some extras.
It looks like their normal application is solar panels. When I get solar panels in I take off reverse blocking diode. Because I use a charge controller and I am not worried about losing a little bit of power if some of the panels become shaded. I would rather get that extra half volt all the time and lose a few watts some times when some panels become shaded. Instead of losing that half volt all the time, just to save a few watts if some panels become shaded.

A more economical solution for under driven alternators might be to just install 3 of these shcottkys between the stator and the voltage regulator.
