Electronic Tachometer
The face of the instrument is printed to look identical to a standard mechanical instrument, it has the correct 120mm diameter case and is calibrate to read the standard rev range. The instrument is identical in all visual aspects outboard of the dashboard - in other words the part you see in the car, but uses a slightly different shaped casing which is hidden behind the dashboard.
The mechanism is programmable via user accessible switches to ensure the instrument will operate correctly with any type of trigger signal from a standard coil pulse to electronic fuel injection. This Electronic Tachometer is completely new, it contains a stepper motor type mechanism that ensures full scale deflection can be achieved. The two warning lights are included. The ignition light is red and the oil light is green.
