Description of ⚡ ESI 304B 20 Amp Fuse Buddy ATC Tester: Ultimate Fuse Testing Solution

Can test circuit current up to 20 amperes - an easy way to check fuel pump amperage. Clever design allows for easy connection into fuse sockets. Fuse Buddy ends are molded into the shape of the fuse itself. During testing the fuse is removed and replaced into the Fuse Buddy; this way the circuit being tested maintains fuse protection. Fuse Buddy stays put and won’t fall out of the socket like test probes do.

Terrible Fuse Tester for Automotive Use

This product is frustratingly inefficient. Through trial and error, I found that it was simply unreliable and gave inconsistent readings. While it might provide some help, more often than not I was left with insufficient, unclear data. It's a waste of both your money and your time.

Pros
  • None
Cons
  • Inaccurate and Unreliable

it does the job, with a few quirks.

I have both 304B and 302M, after about a year the 304B started draining the internal battery even when it was turned off. It's a great tool, but there's no timed shutdown. So you could go through a lot of small A23 batteries. It doesn't readily accept auto-reset circuit breakers, a thing that can be costly in the form of fuses. In many cases, parasitic hood detection has saved me in both automotive and marine applications, or anything related to ATC or MINI fuses. I recommend buying a new…
