Engineering Report

Chris Ostafew / Aravind Seeni Reporting


Generator/Electricity:

Wendy

Hobbs Meter: 3293.6 hrs [ +23 hrs since yesterday ]

Voltage: 117 VAC

Frequency: 60 Hz

Oil Level: 7/8

Oil Pressure: 32 PSI

Water Drained: no


Notes/Comments:
Moved wendy back onto genshed metal plate. She's worn a grove roughly
1/2 way through the plywood now. Further, the fitting for the hose
that goes from the aux fuel solenoid to the on-board tank is leaking at
the solenoid end at roughly 1-2 drips / min. The hose routing was
poorly selected and the results are now starting to show. Not sure if
we'll be able to get to it but it should be noted and changed when
possible otherwise that hose is going to be rubbed through by the speed
adjustment (?) knob. It's dark now, can take photos tomorrow.

Notes/Comments:
Adjusted transmission linkage today on green monster. Appears to have
much cleaner shifting abilities into/out of R/N/H/L but still needs
some adjustment.
