Hiya Kurt,
Should work...sorta. You'll need 4X the resistor value (and wattage) 
and the alternator will put out 1/2 the amperage. Curious why you 
don't use a rheostat?
Good Luck! Bob-O
>Greetings all,
>
>I have a DC generator similar to the design in HP#2.  A Honda horizontal
>shaft engine and a Chrysler 70 amp alternator with a resistor in line to
>the field to hold the output to 80% of full rated power.
>
>Question:  Someone once told me this exact generator can be used to
>charge a 24 volt battery as well as a 12 volt.  The feeling was that if
>you excite the field with 24VDC it will put out 24VDC.  Before I chance
>the deal with the smoke, I thought I'd ask if anyone has done this.  Are
>the Diodes rated for the higher charging voltage?
>
>Thoughts appreciated -- Kurt Nelson
