Tacho driver from Emerald to allow older style moving coil type tachometers to be controlled by the Emerald Engine Management Systems.
Some early tachometers will only trigger from the high voltage spikes normally seen on an ignition primary connection (coil negative). This Tacho Driver module will convert the ECU’s +12v square wave tacho signal to a high voltage (150v to 300v) signal to drive the tachometer.
For more information, please see the technical drawing below.
Estimated dispatch time within 5 working days.
