Digital Fuse Current Tester — Battery Drain Finder

Chase down the drain that's killing your batteries overnight.

When something's pulling power while you sleep and you're waking up to a dead start, this reads current draw through each fuse — 0.01 to 19.99 amps — so you find the circuit doing it instead of guessing. Plugs into the fuse slot, reads the load, points you at the culprit.

For the driver who does his own electrical and would rather fix it himself than book shop time.

Find the drain before it finds you.
