Garage Field Notes
Saved me a $200 mechanic fee!
My AC stopped blowing cold air and I suspected a bad relay. Plugged this in, got an immediate RED light on the compressor relay. Swapped it out and fixed! Absolute lifesaver tool.
Must-have for tracking electrical gremlins
Tracking down intermittent fuel pump issues on old trucks is a nightmare. This 12V/24V checker caught a high-resistance contact issue instantly. Built tough, heavy-duty clips, works perfectly.
Super simple, even for non-mechanics
No complicated digital multi-meter settings to learn. You just clip it to the car battery, plug in the relay, press TEST, and watch the green or red light. Foolproof design.
