Automotive Fuse Tester 0-20A AC DC for Standard & Mini Fuses

A Fuse Buddy tester for measuring current draw directly at the fuse box on standard and mini blade fuse circuits. It reads from 0-20A on DC and AC circuits, giving a straightforward way to check electrical load without awkward improvised connections.

Used for automotive fault finding, this type of fuse box tester helps when tracing parasitic drain, checking accessory circuits, or investigating electrical problems during vehicle maintenance and servicing. Handy for garage work, workshop diagnostics and home vehicle repairs, it allows you to test at the fuse socket itself, which can make circuit checks quicker and easier when working through fuse-protected systems.

The tester connects directly into the fuse socket, so access is more controlled than trying to hold separate leads in place around the fuse box. It is intended for standard blade fuses and mini blade fuses, making it useful across a range of common vehicle fuse layouts. The 0-20A measuring range suits routine current draw checks, and the direct adapter-style fitting helps reduce the usual hassle around cramped fuse box areas. For regular electrical diagnosis, it is a practical way to make repeat checks with less disruption while keeping testing more consistent.
