How does a marine tachometer work?
The inductive tachometer has an inductive magnetic sensor that detects changes in magnetic flux as the teeth on a flywheel move past the sensor head. This transmits a series of on/off pulses to the meter that are counted and displayed as speed on the tachometer.
What color wire is the tachometer?
Tachometer connection: Connection of the tachometer power (RED), ground (BLACK), and lighting (WHITE) wires are ideal for either system. Connection of the tachometer signal (GREEN) wire will vary with vehicle make, model and type of ignition system.
