Today I finally screwed up the courage to top off the water in my six 6-volt batteries. This was tantamount to doing a yoga asana practice, but more nerve-wracking cuz if you screw up you can die. WIth the help of a turkey baster and a long funnel I believe I managed to do it... the batteries are down low and in a very dark corner. Trying to see what I was doing so didn't over or under fill, and not spill water on the batteries themselves (an exercise in futility), required kneeling on brick floor and use of a strong camping light. After I accomplished this task I decided I wanted to educate myself more about the batteries and solar power system I'm on. I have resources: files from the former owner and of course, the internet. Most of it is still utterly unfathomable to me. Math formulas for converting watts to volts, how to program the charger, blah blah blah. This will take time and patience for my almost 60-year-old brain to absorb. Meanwhile, everything is running smoothly; I now can use my cell phone in the house thanks to a Verizon booster which works really great. My next task is to put a little bleach in the water cisterns for cleaning purposes, and then research alternatives to bleach. Then its into town to get a driver's license and pay for the dump...I have to haul my own trash. Happy trails from New Mexico!
