## Description

Plug a Fuse Buddy Current Loop into a circuit and now you can clamp your current probe over the wire to read the amperes draw.

Review: These Fuse Buddy's are GREAT!!!!! - I work as a professional auto mechanic. I am an ASE Master Tech with advanced certification. I purchased this Fuse Buddy to use with my Snap-on Low Amp Clamp. With this Fuse Buddy I am able to plug it into the fuse and then clamp my low amp clamp around the loop and diagnose a circuit. When I purchased this I was going to diagnose a problem with a fuel pump. With the Fuse Buddy I didn't have to go under the car I could easily do my diagnoses with my amp clamp and the fuse buddy. The best part of it was when the problem happened I could see that I was still getting normal amperage to the fuel pump so I knew then that the problem was not with the fuel pump. These Fuse Buddy's are a great find for anyone working in the field and wants to save a little time. The best part is that you can use them on any electrical circuit that requires a fuse. This comes in real handy when the component you want to test is hard to get to such as a fuel pump. Most automotive electrical devices are in series with the fuse so if you check the wiring diagram and this is the case then the amperage will be the same threw out the circuit. Like I said these Fuse Buddy's are GREAT!!!!!!!!!!
Review: Finally! And it works! - Finally someone makes devices like this instead of us trying to get a bunch of male and female wire connectors, fuses and wires to do lab scope tests on cars. Just pull out the fuse, use the Current Loop that fits the fuse socket, install the fuse you removed from the vehicle in the side of the Loop, install the Loop back in the fuse socket and test the devise or circuit. Good quality, good size, fast results and cannot damage the vehicle. They just need to make one that fits the low profile mini fuse now.

## Features

- Great accessory for any current probe or automotive scope
- Just clamp your current probe over the loop to access the amperage draw through a fused circuit
- Easy testing access; plugs right into fuse socket; no more hand made adapters
- Testing range 0-30 amperes, do not exceed 30 amperes
- Also handy for installers needing to monitor circuit amperage limits
