Tachometer signal voltage booster -894-
An external module to condition the ignition signal from an ECU ( square wave) to drive a Voltage driven tachometer designed to connect to a coil negative terminal
External Module boosts low voltage ECU square wave to drive voltage driven tachometers
This module generates a signal compatible with RVC and other Voltage Driven Tachometers from the signal generated by an ECU or similar. The circuit board is submerged in conformal coating for at least 5 seconds, dried and then heatshrink is applied over the whole to make it resistant to the damp conditions experienced on vehicles.
