If  you put a voltage meter on the stator lighting circuit, it it will usually make about 50 volts AC at high RPM without a load on the system.  If you check the voltage out of the voltage regulator without a load on the system, it will usually be about 13 to 15 AC volts.  It will not charge a battery unless you put a rectifier to convert the voltage to DC

If you check the peak voltage out of the ignition source coil on the stator it should be be at least 100 volts peak and over 150 peak at higher RPMs.

OK cool. I'll have to look into the rectifier.  I was wondering because I was thinking about installing a cooling fan for the radiator

Cooling fans has been a hot topic on some of the other forums recently.  Your stator will not generate enough power to run a cooling fan when the engine RPMs are low.  Adding a good sized battery would provide power for the fan when speeds are slow as long as the low speeds are not continuous for more than a few minutes at a time.  If you putt around for a few minutes with the fan running you will need to run the engine at medium to high RPM without lights for 2 to 3 times the time the fan was on to re-charge the battery.

I am thinking of doing the same thing cause in the dunes you end up going the same direction as the wind and no air is getting to the radiator
