3.Connected to ignition power supply and can be displayed
Note:
That connecting plugs do Reinforcement. To prevent vibration.
The hall sensor & tachometer wire Leave from the Ignition high-voltage wire,
And receiver wires over 30cm
Connection tachometer is not recommended after the use of flight,
Best to remove the Y wire to restore the original sensor connection
If ignition have an additional tachometer pinout.
You must be connected to dedicated tachometer signal wire.
