I had 4 LED's and a resistor to put a load on the circuit so that there wouldn't be any additional noise generated to affect the oscilloscope's reading. I found this pic which shows what the reading should be
View attachment 63152 but if you look at mine where top hump from the lower negative half of the wave comes up to 12v, on mine the power goes to zero, but it looks like on wave I have, on both sides of the slope it looks like it bumps over then comes down. It sort of looks like to me the wave that was negative is out of phase.
