The battery's charged fine, but no power's reaching the fridge

Possible cause: Blown fuse or loose/dirty connections. Check every connection is secure and clean, and check the 15A 3AG fuse at the rear of the battery (behind the socket powering the fridge), replacing it if it's blown.

Not fully charging in-car

Possible cause: Loose connections or vehicle wiring gauge too thin to deliver adequate charging current. Check the connections are secure and clean, and fit the recommended WAECO RAPS12R-U2 heavy-duty wiring kit to the vehicle.
