We made this next improvement to reduce the battery draw while on shore power. Even when plugged into an AC source our Dometic CF50 cooler was always taking its power from the battery.
Original DC Plug
DC Plug Disassembled
The original cigarette lighter plug was canabolized for parts.
AC to DC Adapter
This 110V to 12V converter will be active when plugged on shore power. It has a backup connection for 12V which means if shore power is cut, it will automatically provide continual power from the battery to the cooler compressor (B- B+ connection)
Original DC Plug Now Attached to Permanent DC Terminals
Connecting to House (B) Battery
Ready to test
Attached in Galley
Some Supervision Required
Secured on Plywood Backing
Baltic plywood painted and mounted during last year’s galley project (here) made it easy to secure the adapter.
Plug to 110V GFCI Outlet
Cooler with its new mylar blanket (post of the making of here) back in place and ready for the season to begin.
