The Sealey Automotive Back Probes 15pc (VS225) is designed for automotive technicians and DIY enthusiasts needing to access and measure electrical signals within wiring harnesses. Its key benefit is precise access to tight spaces, enabling accurate diagnostics without damaging wires. A potential caveat is the specialized nature of the tool, requiring user familiarity with automotive electrical systems. This set includes 15 probes in five distinct colors for easy identification, featuring protective tips and a narrow 0.7mm diameter for accessing difficult-to-reach connectors. It comes conveniently organized in a clear plastic storage case.

These probes are designed to allow technicians to measure electrical signals (like voltage or resistance) directly within a wiring harness connector without disconnecting the wires, enabling live testing.
The five distinct colors help users differentiate and keep track of multiple probes when testing various circuits simultaneously, preventing confusion and ensuring accurate connections.
The probes have a sharp tip designed to penetrate insulation cleanly and a narrow diameter to minimize damage. However, excessive force or misuse can still potentially damage the wire insulation.
The probe tip has a very narrow diameter of 0.7mm, allowing access into tight spaces and the rear of most automotive connectors.
Yes, they are designed for general automotive use and are compatible with most standard automotive wiring harnesses and connectors.
They should be stored in the provided clear plastic case. This protects the sharp tips from damage and prevents accidental injury.
Yes, these probes are designed to connect to standard multimeter test lead sockets, making them compatible with most digital multimeters.
Ensure the protective tip cover was removed before use and that no debris is obstructing the tip. If repeatedly used on tough insulation, the tip may eventually dull and require replacement of the probe.
Verify you are attempting to back-probe the correct point in the connector. The 0.7mm size is designed for tight spaces; ensure no other obstructions are present.
Gently push the probe further into the wire insulation to ensure a solid connection. Check for corrosion or dirt on the probe tip and clean if necessary.
Use a permanent marker to re-label the probe handles if the original color coding becomes unreadable. Clean the probes thoroughly before attempting to re-label.
Setup: The Sealey VS225 probes require no complex setup. They are ready to use directly from the storage case. Simply select the appropriate color-coded probe for your diagnostic needs.
Compatibility: These probes are designed for use with standard automotive wiring harnesses and connectors. The 0.7mm narrow tip is ideal for accessing the rear of most common automotive electrical connectors. They are compatible with most multimeters and oscilloscopes that accept standard probe inputs.
Care: To maintain the performance and longevity of the probes:
