Nope. DC.
I checked the output with and without the diode.
Without the diode, I was getting around 30 VAC.
From an earlier post....
RMS AC Voltage = 30 Volts (measured)
http://www.bristolwatch.com/ele/basi...tification.htm
Peak Voltage = RMS Volts * 1.414 = 30 Volts * 1.414 = 42 Volts
Full Wave Rectified DC Voltage (measured) = Peak Voltage * 0.637 = 27 Volts
Half Wave Rectified DC Voltage (measured) = (Peak Voltage * 0.637) / 2 = (42V * 0.637) / 2 = 13.5 Volts.
If there is a diode in the key-box wiring (half wave rectifier), I expect to see 13.5 Volts based on the measured 30 Volts AC.
So I guess I would expect around 30+ RMS Volts AC measured at the stator's output at around 3600 RPM. A single diode (half wave rectification) will give ~13.5 Volts intheory. A full wave rectifier will give ~27 Volts if the input is 30VAC. Not sure why you are only getting 10VAC. Is there a load connected? I tested with one probe going to the block and the other probe on the end of the single wire coming from the stator. No load connected.
It seems like your 10 RMS Volts AC gives a peak voltage of 14.14 V. Half wave rectified would read 4.5 Volts.

I posted this in the next thread where I make performance mods to this engine.
My threads are like my thoughts. Scattered all over the place
Maybe you can tells me what this test shows me??? I don't really know how to use this information.
It shows RPMs and Voltage measured across the battery (with and without a 1 amp pump running). I up to this point have just taken China's word that this pump draws 1 amp. Have not tested.
(Approximately!!! +/15 RPM +/- 0.15 Volts)
Across the battery with the pump running...
2350 RPM 14.00 Volts
2875 RPM 14.25 Volts
3150 RPM 15.00 Volts
4075 RPM 16.38 Volts
Across the battery withOUT the pump running....
1350 RPM 15.50 Volts
1625 RPM 15.75 Volts
2450 RPM 16.25 Volts
3050 RPM 16.50 Volts
I assume if I add the 18watt light I want to use, The voltage drop would be even greater???
Around 3100 RPM gives 16.5 Volts with no pump, but 15.0 Volts with a 12 Watt draw on the battery. I assume an additional 18 Watts might put me around 12 Volts??? I also assume that the higher the RPMs are, the lower that voltage drop will be. ????
I have an idea, but don't have a clue. LOL
