ITEQ Power Circuit Probe Tester

The ITEQ Power Circuit Probe Tester is a 6V to 24V DC test light designed for automotive electrical diagnosis. It suits mechanics and DIY owners who need to check polarity, continuity and short circuits on cars, trucks, motorcycles, boats and RVs. The kit includes a probe tip, alligator clip, electrical tape and a storage bag. It is a new electrical system tool for professional and home use.

Sustained Load Behaviour

Overload protection automatically disconnects the circuit when current exceeds 7A and sounds a buzzer alert during extended testing sessions. This safeguard prevents damage to the tester and the vehicle wiring while you trace faults across the full 13ft lead. The corded electric design maintains consistent power without battery fade during long diagnostic jobs. Component activation remains stable throughout the procedure.

Thermals Noise and Power Draw

The unit draws power directly from the vehicle 6V to 24V DC system so it adds no separate battery drain. Operation is silent apart from the overload buzzer which only sounds when the 7A threshold is breached. The compact probe body at 10.43 L x 3.54 W x 1.57 H inches and .694 pounds stays cool during normal use. LED indicators provide visual feedback without audible distraction.

Questions about this item

How much current does the 6V-24V probe draw before its overload protection trips and sounds the buzzer?

The built-in overload protection automatically disconnects the circuit when current exceeds 7A and provides a buzzer alert.

Does the tester need a separate power supply or does it run from the vehicle battery?

It connects to the vehicle battery with the large alligator clip and a 13ft test lead for full-vehicle reach.

Can I use the probe on a 12V car system and still test continuity on relays and fuses?

Yes, the tool works on 6V-24V DC systems and checks continuity of switches, relays, diodes, fuses and circuits.
