Lisle Master Relay and Fused Circuit Test Kit 69300 – 8 Relay Jumpers, Multimeter-Ready Test Leads

The Lisle 69300 Master Relay and Fused Circuit Test Kit is a portable toolkit for testing automotive relays and accessing live fused circuits quickly—without piercing wires.

When troubleshooting electrical faults in cars, trucks or SUVs, having a non‑invasive, adaptable relay test kit speeds diagnosis and reduces the risk of damage. The Lisle 69300 bundles multiple relay jumpers, a multimètre-ready test lead set, terminal leads with switch/fuse/power options, and a relay puller to help technicians reach and test relays and fused circuits across a wide range of vehicles — including many domestic and European makes.

How does this kit help me test relays without cutting or piercing wires?

The kit uses relay test jumpers and dedicated terminal leads that clip or plug into relay sockets and fuse boxes so you can measure voltage and continuity without altering factory wiring. That preserves connector integrity and reduces repair time.

• Eight relay test jumpers that fit most common standard relays
• Terminal leads with built-in switch and fuse options for controlled testing
• Multimeter-compatible connectors for safe voltage/current checks

Which vehicle relay and fuse types can I test with the Lisle 69300?

The supplied jumpers cover the majority of popular automotive relays, and the adaptable terminal leads extend the kit’s reach to less-common configurations found on some European cars. You can test common Bosch-style and standard plug-in relays plus many factory fuse circuits.

• Standard automotive blade and cube relay footprints supported
• Terminal lead options suited for Volkswagen, BMW and similar European applications
• Fuse access points for checking circuits without removing or splicing wires

What tools are included for safe measurements with a multimeter?

The kit includes a test lead assembly that securely connects relay jumpers to your multimeter, enabling voltage and current measurements while keeping hands clear of live terminals. Fused leads and an integrated switch let you control circuit power during tests.

• Test lead kit with secure connectors for reliable multimeter hookup
• Inline fuse holders to protect instruments and circuits during testing
• Switchable leads to apply or interrupt power without removing components

How does the relay puller improve access and removal?

Relay puller pliers in the kit give extra grip and leverage to remove stuck or hard‑to‑reach relays without damaging the relay housing or nearby wiring. This speeds replacement and prevents connector deformation.

• Pliers shaped to grab common relay housings securely
• Non-marring tips help preserve relay terminals and sockets
• Compact design fits crowded engine bays and fuse compartments

Who this kit is for: professional mechanics, independent technicians, and automotive DIYers who need a compact, non‑destructive way to verify relay operation and check fused circuits across many vehicle platforms. If you regularly diagnose electrical systems or want to reduce time spent chasing intermittent relay faults, the Lisle 69300 provides a practical, reusable toolkit to simplify accurate troubleshooting without wire splicing.

Key benefits at a glance:

• Saves diagnostic time by enabling direct relay and fuse access
• Avoids wire damage by eliminating the need to pierce insulation
• Broad vehicle coverage including many European models
• Packed for portability with tools for removal and safe multimeter connections
