All, today I feel like I have reached another significant milestone on my
project, and sometimes the "celebration" of posting a status update is all
the reward we get : )

Seven and a half years ago I started rebuilding an older K-250 from the
bare hull up. Today I started testing the electrical systems (HP air
systems have successfully been tested). It was rewarding to see the battery
monitoring system, depth sounder, aft thruster actuator, interior lights
all come to life as expected. The general electrical system seems healthy.

Later today I will try the thruster controllers. If I have a problem, it
will be here. I am experimenting with "inexpensive" eBay controllers and I
am emotionally preparing for a hardware failure. Maybe I will be presently
surprised. If things go well I am on track for having enough operational
systems to start my in water testing this year. Even if I have to rework
the controllers I should be in the water next year for sure.

I am really looking forward to joining the "operational" sub guys.

Steve
