AGREE with Lloyd. If you can get a eutectic system working correctly it will save nightmares of electrical
problems. "COLD" stored in a eutectic is MUCH more efficient than COLD stored in a battery
, perhaps 1,000% more efficient.
CHECK the insulation
. It is no good fixing the cooling
if it is not well insulated. Our boat had the old "white granule" type insulation
which had become saturated with condensation water
. I had to tear the whole contents out and put in the new type of insulation with sealed cells.
You need to discover where you are losing gas. Get yourself a freon snooper. I used the old fashioned type with a propane
heated detector. They are not very expensive and just as sensitive as the fancy electronic ones.
When you discover the leak, replace or repair the culprit. Kollman Marine
are (used to be?) a great source for component parts
After I rebuilt our freezer/refrigerator with oversized sealed 220 volt compressors (to minimize generator
running time) and extra eutectic plates, I could leve the baot for 3 days and on return the freezer would still be below 32 and the refrigerator
below 40. Daily re-freezing the eutectic took less than an hour each moring or a couple of hours after being off for 3 days. There is NO WAY you can economically get this amount of refrigeration
from a cycling battery
