Summary: Unstuck solenoid on CO2 profile system, fixed CR10X power on new soil CO2 profile, tram had a loose wheel and low battery - wheel fixed.

2012-03-19 I arrived about 12:00 noon PDT. There was diffuse sun with high thin clouds and little to no wind. The ground is wet with standing water in the low areas. The grasses are finally beginning to look green. One of the channels on the CO2 profile system was not flowing properly – I could hear the pump bogging down. It seems on of the solenoids was sticking (maybe channel D – top). I banged on the solenoids and it seemed to fix it. We may need to replace the solenoids soon. I added a 24V to 12V DC-DC power supply to the new soil CO2 profile that Siyan installed. I removed the wire connected to the fence charger that had been used to power the CR10X. The tram was not running. The south wheel had lost its cotter pin. I added a temporary pin and plugged the tram in to charge. The internal battery was about 6V, I’m not sure it will work or not. Both computers were running and seemed to be working okay. |
