Patent Images
1. A fused circuit testing apparatus for an electrical power source in a system having at least one fuse receptacle adapted to receive a protective fuse at an electrical input terminal and with an electrical output terminal to an accessory circuit, and including;
- a fuse adapter means having electrically isolated input and output terminals received in the input and output terminals of the fuse receptacle, the input terminal of the adapter being in electrical continuity with the input terminal of the receptacle, and the output terminal of the adapter being electrically isolated from the output terminal of the receptacle, said input and output terminals of the adapter receiving the fuse therebetween,a selective test circuit means switching electrical continuity from the output terminal of the adapter means to the output terminal of the receptacle and alternately to a circuit continuity indicator means.
