Automotive circuit tester for quick detection of low-voltage faults across vehicle wiring, fuses and lighting circuits. Gain confidence when checking headlights, taillights, turn signals and sockets with the Zoe & Jim Circuit Tester. Is the build quality and accuracy up to workshop standards?
⚡ At a Glance
- • Voltage Range: 3-70V DC detection with red/green LED polarity indication
- • Best for: DIY mechanics and vehicle electricians checking low-voltage circuits
- • Not ideal for: High-voltage systems or diagnostics above 70V
Alligator-clip connection supports bidirectional voltage testing and LED polarity feedback. Stretchable long cable and probes reach awkward areas for lighting and fuse checks.
Clear Polarity Identification - thanks to bidirectional LED indicators
Alligator clip connects to either negative or positive ground and a circuit-board LED shows polarity, with red for positive and green for negative. The probe and indicator arrangement lets the operator confirm polarity without additional meters.
Faster diagnosis of reversed wiring or poor grounds, reducing time spent tracing faults. Safer checks by immediately showing whether a circuit is live and which polarity is present.
Reach Tight Spaces - with stretchable long cables and flexible probes
Approximately 110 inches of cable length and anti-bending tail-line design provide extended reach while resisting poor contact from kinks. Probes are long enough to access headlamp and fuse-box areas without awkward positioning.
Access to recessed connectors and cluster-mounted fuses without repeatedly moving the vehicle or components. Cleaner workflow during road-lighting and turn-signal checks.
Reliable Low-Voltage Fault Detection - thanks to a 3-70V DC testing range
Designed to detect short circuits and open circuits across power, grounding and wiring systems within the 3-70V DC band. Suitable for checking headlights, taillights, turn signals, sockets and fuses.
Quick identification of blown fuses, broken wires or poor connections in typical vehicle electrical systems. Performances noted by users compare favourably with more expensive models, supporting routine workshop use.
