MiniGen - Output Current

The output of my minigen at 11.9Hz is 1.1Vpp with an offset of 1.5VDC. When I connect a resistive load of 1KOhm, I only see a 0.001,5mADC current draw. I don’t see an AC current draw at all. Why don’t I see AC current from the output?

Here is the schematic for the MiniGen.
