ESI 307M Fuse Buddy Mini Current Loop

great for testing circuit

You can get an amperage draw reading thru the fuse test port by using a multimeter forcing the current(amperage) thru the meter leads NOTE: Polarity has to be correct orientation(or you will blow a meter fuse).. But this tool is idiot proof basically. Just plug and play and put an amp clamp thru the red wire hoop. Take your reading and your done. Then troubleshoot the issue if need be. This tool is easy to use compared to a conventional amperage test procedure

Use this with a DC current clamp and measure amp draw on various components like a fuel pump. Very nice tool to have.

Used it to check for issues with the lighter socket on the dash, kept blowing the fuse, so replced the fuse with the Fuse Buddy and checked the amp load, worked well...

Even though you can use a multimeter to test the current flow in a system, with this it isnt limited to 10 amps a multimeters fuse is and you can quickly use to measure current on a system without having to tie into the system if you can a inductive clamp.

Use this all the time to test circuits or parasitic draws. Nice addition to scope or meter with an amp clamp. Sometimes the casing is big to fit between other fuses or relays.

Another top product from the manifacture, well made, I would buy again.

This is a great product to assist in the measurement of current draw in automobiles, but requires a non-contact DC digital clamp meter. The quality, design and construction of this product rate a 5 star rating.

This is the perfect accessory to take measurements with my low amp probe. No more crawling under the car to measure current from hard to reach wiring. It can all be conveniently done at the fuse box. I also purchased ESI 308B to cover both common size fuses...

Great, easy to use little current loop tester. Great for current ramps on injectors and coils when theyre difficult to get to. Simply remove the fuse and access all the waveforms for all of them.
