[C320-list] Fridge Usage

[Warren Updike]

Colin, you've had a lot of good suggestions to address your problem.
Trouble is, without knowing how your batteries are wired, charged, what
other loads there may be, and a whole bunch of other things, all you this
list can give is topical suggestions.  It's not at all clear whether this is
purely a usage/charging issue, a wiring fault, or something else.  
I urge you to do a power audit using the spreadsheet from the web site; and,
if there is a fellow boater nearby that is capable of assessing your whole
system with the use of proper equipment, to try to get his assistance.
I hope you get to the bottom of this.

Cast your minds back a few weeks when I queried the time our fridge was
running. It generated a lot of discussion, and we learnt many energy saving
ideas for the fridge.  Thank you all.
However
Generally it seemed that about 30% t 40% running time was normal.  Now I
have had my batteries checked by our local supplier and they are fine.  At
less than two years old I would hope so.
I have still have the problem of lack of power.  We went 16 hoiurs last
weekend and then there was insufficient power to start the fridge.  Bear in
ming that we have 2 x 150A house batteries and a separate starting battery.
The general comments indicated that we should be okay for 48 hours, as all
three batteries indicated being fully charged when we left the marina
If anyone can shed some light on this I would be grateful.
