zzoldtown Posted July 14, 2022 Share Posted July 14, 2022 Hi all I have a 24V FFR, with the generator and shunt box on the bulkhead and an additional box in the rear tub with red and black screw down connectors. I want to wire up some USB charging sockets. My question is, can I connect up directly (via a fuse) to the rear tub box. Thanks in advance.

fv1609 Posted July 14, 2022 Share Posted July 14, 2022 If you have no radio batteries connected, those coloured terminals only become live when the main relay inside the Generator Panel closes. Once the generator is giving output with the engine running the relay closes & in so doing switches the generator output to the vehicle & radio batteries. There is no connection between those terminals & the vehicle batteries until the relay closes with the engine running. If you only want your USB charger to work with the engine running it will work but not when the engine is not running. Quote Link to comment Share on other sites More sharing options...
