Took down my old outdoor light which has only worked on & off since we moved in, (yes I know that’s how lights work) replaced it with the ring floodlight camera, checked all the connections then switched the power on, nothing, rechecked all the connections, no problems there, went to the switch, took the face plate off & checked the connections, all fine, went to the fuse box in the hall, no tripped fuses, went back to the switch, noticed another cable coming from it leading to a “FUSED BOX” underneath, swapped the fuse,TA DA, all is now good, last place I looked should have been the first.
