Engineering Report
Marcus Medley Reporting

Generator/Electricity:

Wendy: not used
Casper Hobbs Meter: 685.5 hrs (+18 hrs since yesterday)
Voltage: 101 VAC
Frequency: 54 Hz
Oil Level: 3/8
Oil Pressure: 0 PSI
Water Drained: no
Notes/Comments: Gas Generator - will run twice Morning - refueled with 5 gallons (3 o'clock) and used for NDX test. The new generator was used during this period, but the HAB lost power anyway. I couldn't figure out how to get the Xantrax to accept power from the generator. We were without power for most of the day. Evening - started at 5:20 no refuel. Don came by around 4 o'clock to help with the generator/xantrex problem. The new generator was found to be of reverse polarity, and this fixed the problem long enough for Don to leave. Soon after Don left the power went out again. I reconnected the old generator and after many minutes of troubleshooting I was able to get the xantrex to allow the generator to charge the batteries.

Xantrex Inverter/Dynasty Batteries:

Time - Voltage (Temp Comp) - Load - Temp - Generator Running
04:19 - 23.2 - 4 - 17 - Yes
