Test Multipin Kit

Jaltest Test Multipin Kit (SKU 50003012) — $70 The Jaltest Test Multipin Kit (part 50003012, $70) is a set of test pins and probes for back-probing connectors and taking live measurements at harness connectors without damaging the connector body or weather seal. This is an essential tool for circuit-level electrical diagnostics on commercial trucks, construction equipment, and agricultural machinery — the right way to check sensor signal voltages, ground integrity, and supply circuits at a mated connector under load, without unplugging the sensor and affecting the readings. Why Test Pins Matter for Diagnostic Work When Jaltest flags a sensor fault or a communication error, the next step is verifying what is happening at the circuit level. That means measuring voltage at the sensor connector with the connector still mated — which requires thin probe tips that slide alongside the connector pins without breaking the weather seal or spreading the pin cavity. Standard multimeter probes are
