Hi John,

You have several good points, but unfortunately I have to run the genset 
anyway.  My autopilot is hydraulic! Believe me with any wind over 10 kts and a 3 
-4 sea the autopilot works quite a bit, so it brings it's battery down in the 3 

The isolation is a total disconnect from any of the other batteries onboard. 
The device I am using is called "DIGITAL ECHO CHARGER" You can find this for 
sale at WEST MARINE under their number 333669. This device is actually a 
solenoid which closes the circuit. Whenever the input voltage goes above 14 VDC 
either caused by running the genset thru the 3 stage charger, or the alternator on 
the prime mover, the DEC will close its contacts and supply 12+ volts to the 
isolated battery. Unfortunately it is not cheap! West Marine sells this item 
for $130.00. 

We have sailed something in the order of 350 hours in the past 18 months 
using the setup I have subscribed. In all of that time the Mini-ITX and screen has 
worked flawlessly.
