I have a fridge that doesn't run when on shore power but when i'm on batteries it does run. everything else seems to be working correctly. The fridge did at one time work when on boat power. any help would be appreciated.
The fridge is most likely 12V. When on shore power its the battery charger that supplies the extra juice to keep 12V systems going. Just make sure your charger is turned on when on shore power otherwise you'll run the house batteries down.
