I'd like to test the Tachometer input to my GRT Sport (with EIS) EFIS unit before running the aircraft engine.
The EIS Tach lead connects to the "P" lead of the Magneto through a resistor to the EIS tach input.
I was wondering if anyone can suggest a way to test the Tachometer readout of the EFIS/EIS without running the engine?
Tnx, AC
