Summary: Jim moved signboard generator, inverter connected to generator, air conditioner running.

Arrived about 8:30am. Cold and foggy. The fog opened up a little while I was there but came back in thicker before I left. Water level is higher, still lots of birds.

Met Jim and he moved the signboard generator out to the pump location (location of previous generator) where the existing power line starts for the run to the box. I connected the 1000W pure sign wave inverter to the battery on the generator with two pairs of #6 cables. The inverter is in a Campbell enclosure next to the generator.

I set up the CH4 system with the diaphragm pump and it seemed to run well. I had to adjust the by pass valve inside the LGR analyzer for the smaller pump. Air conditioner is powered and running (though not much cooling needed).

I plugged in the scroll pump and it tried to spin very slowly a couple of times before I disconnected it. I think we need another or a larger inverter to run the scroll pump.

I drove around the perimeter of field 1. Road to the west is good but maybe not wide enough for the trailer. Fields further to the west are also flooded and full of birds.

Left for Sherman about 10am.
