Hey, Bob M and you other electrical gurus

Okay, I've been following all the 6V versus 12V threads, read the conversion articles, studied Bob M's diagrams. There seems to be a consensus that changing the 6V regulator on a 6V generator to a 12V regulator and installing a 12 volt battery will make a 12V system. Fine and dandy. I like that, cheap and easy (so far). The one question I haven't been able to answer concerns the amount of "power" (expressed in watts) available.

My understanding is that Watts equal Voltage times Amperage, or P=E*I. When the generator is tricked into 12V operations does the amperage stay the same?

That is, my generator puts out 10 amps at 6 volts (cause that's easy to multiply). Therefore I'm getting 60 watts. 60 watts=6 volts times 10 amps, so if the amperage stays at 10 amps I would have 120 watts when the generator operates at 12 volts.

Or am I working the wrong side of the equation? If wattage stays the same, then I would have only 5 amps.

I want to go to 12 volts so I can hang some lights on the M, those 6 volt dudes just don't get the job done. And by "tricking" the generator I don't have any rewiring (except for new lights), I have the magneto, so I don't have to worry about a resistor, or a DPDT switch.

The question is (after all of that) will I be getting 120 watts as in my example, or still getting 60 watss and reduced amps?
