Replacement Probe for #6806

The Replacement Probe for #6806 is an AutoMeter tachometer pickup designed to restore accurate RPM sensing in Pro-Comp 5-inch tachometers that have experienced probe failure or degradation. This is the factory-approved replacement component for serious enthusiasts, professional mechanics, and engine builders who depend on precise ignition signal detection for tuning, diagnostics, and performance monitoring. Tachometer probes are subject to electromagnetic interference, thermal cycling, and connector corrosion—making this OEM-spec replacement essential for maintaining signal integrity on any high-performance or vintage engine setup.

This pickup probe functions by detecting the ignition pulse generated at the distributor or coil, converting that electrical signal into the RPM readout displayed on your Pro-Comp tachometer gauge. The probe reads the magnetic or capacitive fluctuations in the ignition circuit and relays clean, jitter-free data to the gauge face, ensuring stable needle response under load, during acceleration, and at idle. AutoMeter engineered this probe with noise-filtering circuitry and shielded harness connectors to eliminate false readings caused by alternator noise, fuel injector pulses, or nearby electrical equipment—critical performance factors in modern and modified engine bays where EMI sources are abundant.

This replacement probe is ideal for anyone restoring a non-functioning AutoMeter Pro-Comp tachometer or upgrading an existing gauge system without purchasing an entirely new unit. Installation is straightforward: disconnect the old probe from the harness, route the included wiring through the firewall or engine bay, and connect the new pickup to your distributor or coil primary wire using the integrated connector. This SKU 5211 probe maintains full compatibility with AutoMeter's #6806 Pro-Comp 5-inch tachometer systems and ensures OEM performance specifications for accurate, real-time engine speed monitoring in street, race, and restoration applications.
