Summary: Added battery to system. Found leaks in 7700 reservoir tubing.

We arrived around 15:00 PST. It was cool and calm. The alfalfa appears to be regrowing slowly.

This was a relatively short site visit to add a battery to the solar system. Success on that front.

The 7700 reservoir was low although it was just refilled last Thursday. We forced the cleaning to run and found two leaks in the reservoir system -- one where the tubing attaches to the reservoir on its way to the 7700, and another in the plastic filter (same place as the rice leak last year). We cut out the leak in the tube and taped up the leak at the filter.

Readings looked good.
Cleaned the flux sensors.
