Fluke 2149102 Rigid Back Probe Pins Electrical Test

Product Description

The FLUKE 2149102 is a set of rigid back probe pins designed for accessing electrical connectors in tight, weatherproofed wiring harnesses. Each pin measures 2 inches in length and is built to pass between weather pack seals and wire insulation without damaging either. A sharp point ensures positive contact at the conductor, while the pin's own insulation prevents unintended shorts to adjacent wires. Electricians and automotive technicians use these pins as a back-probe accessory alongside a standard test probe or multimeter lead to take live circuit readings without unplugging connectors.

These rigid back probe pins are suited for diagnostic work on low-voltage control circuits, weather-sealed automotive connectors, and similar applications where access is restricted and probe-tip contact quality is critical. The 2-inch rigid design gives the technician enough reach to seat firmly behind the connector seal while keeping the probe lead clear of surrounding components. They pair with standard test leads and multimeters for voltage, continuity, and resistance measurements on live or de-energized circuits.

Key Features

• 2-inch rigid length passes between weather pack seals and wire without connector removal
• Sharp tip ensures reliable electrical contact at the conductor
• Insulated shaft prevents shorting to adjacent wires during live-circuit testing
• Functions as a back-probe accessory with standard multimeter test leads
• Supports voltage, continuity, and resistance diagnostics on sealed connectors

Compatibility

Designed as a back-probe test accessory compatible with standard multimeter test leads and probe sets for use on weather-sealed electrical connectors in low-voltage diagnostic applications.

Installation Notes

Back probe pins are installed by electricians and technicians performing live-circuit diagnostics. Insert the pin carefully between the weather pack seal and wire to avoid seal damage; do not force the pin past resistance. When testing live circuits, confirm the circuit voltage is within the rated range of the connected test instrument before probing. Follow applicable NEC guidelines and instrument manufacturer safety ratings for the measurement category of the circuit being tested.
