The new design uses adapters for each fused socket, allowing for easy current draw measurements without having to break the circuit. The kit includes one Fuse Buddy tester with ATO end piece, a mini adapter, a micro adapter, and a socket adapter. Rather than offer a third Fuse Buddy with a new Micro end piece, these adapters can handle all three fuses. This kit includes 306B with ATO fuse fitting and the adapters making connection to the other two fuse types. This tool comes with a one-year manufacturer warranty. The battery is included.
