Operations

Electrical Check

• While underway
  • GPS should show changing Lat/Lon
  • Genset, if on, should show > 5 amp load
  • 12v panel meter at 13 volts, and positive amps
  • Breakers for "Sailing Instruments", "Autopilot", and "VHF" should be ON
  • DC-DC Converter on showing light
  • Fuel should read at least 1/4 full
  • 144v bank volts between 144 & 170 and Amps positive values
    (Note:  Volts actually  read 14.4-17.0 Because decimal point is off by one place) 
  • Motor switch should be on
  • VHF Radio should be on
  • SSB Radio should be off
  • Computer Serial Port should have flickering light
  • Computer "Power Brick" indicator should be on
  • Computer and computer power light should be on and "Chart Navigator Pro" should be running.  The escape key will turn on the display.

• Troubleshooting
  • GPS should show changing Lat/Lon
    • If it responds to button presses, but can't find satellites, then we just need to wait till it locates them
    • if it is frozen, and won't respond to changing button presses, then the power cable in the back should be unplugged and then plugged back in and the unit turned on again
  • Genset, if on, should show > 5 amp load
    • If it shows 0 amps then it has stalled.  If < 5 amps it should probably be turned off
  • 12v panel meter at 13 volts, and positive amps
    • The button under the display switches between volts and amps.
    • The DC/DC converter must be on to charge the house battery
  • Breakers for "Sailing Instruments", "Autopilot", and "VHF" should be ON
  • DC-DC Converter on showing light
    • The switch should turn it on
  • Fuel should read at least 1/4 full
  • 144v bank volts between 144 & 170 and Amps positive values
    (Note:  Volts actually  read 14.4-17.0 Because decimal point is off by one place) 
    • The button on the left turns the display on, and scrolls between four readings: Volts, Amps, AmpHrs used, and Time Remaining
    • Voltage too High:  cause is overcharging due to sailing speed.  Correct by increasing throttle to bring amps display on deck down to about 2 amps
    • Voltage too Low: cause is throttle too high, or speed too low, or fouled prop.   Correct by adjusting throttle, clearing prop, or starting genset
  • Motor switch should be on
  • VHF Radio should be on
  • SSB Radio should be off
  • Computer Serial Port should have flickering light
    • Cause: the computer may have shut off, or the GPS may be locked up.  The computer should come on with the escape key.  If  it has shut down turn it on with its power switch and restart "Chart Navigator Pro" using icon in center of window.
  • Computer "Power Brick" indicator should be on
    • If not, check that the computer is plugged in to the standard 12v outlet around the left side of the instrument complex and that the "outlets" breaker on the right side of the panel is turned on.
  • Computer and computer power light should be on and "Chart Navigator Pro" should be running.  The escape key will turn on the display.
    • Shield the light showing through a hole in the wood to see if it is on.
