Kit Contents & Use

This 50-piece kit supplies 10 stackable banana-plug test leads, 10 alligator clips and 30 stainless-steel back-probe pins in ten colours. It is built for automotive technicians, hobbyists and students who need quick, non-destructive access to connector pins on vehicles, motorcycles or bench circuits.

Installation Notes

The 4 mm stackable banana plugs let you piggy-back multiple leads into a single socket without tools. Back-probe needles measure only 0.07 mm thick and are offered at three angles so they slide into tight harness connectors, fuel-injector plugs or sensor terminals. Alligator clips open to 15 mm and feature a reinforced spring that holds firmly without the insulating sheath slipping during use.

Sustained-Load Behaviour

Test leads use a pure copper core inside flexible PVC rated for 500 V and 5 A, while the copper alligator clips carry 300 V at 15 A. Both materials maintain conductivity and insulation integrity during extended diagnostic sessions in workshops, labs or on vintage vehicles.

Questions about this item

How can I confirm the test leads are functioning correctly after connecting them?

Verify that the 4 mm stackable banana plugs seat firmly in the meter sockets, the alligator clips grip with their built-in spring and the copper conductors show continuity at the rated 500 V, 5 A.

What items are included in the 50-piece kit and what must I supply separately?

The box contains 10 stackable banana-to-alligator test leads, 10 additional alligator clips and 30 stainless-steel back-probe pins; a multimeter or other measuring instrument is not included.

Which of the supplied probe angles should I select for tight connector spaces?

The 30 back-probe pins come in three angles — choose the straight pin for direct access, the angled variant for offset terminals and the hooked version for hard-to-reach contacts.
