HI. I've just bought my engine and have fitted a couple of P-Mags. Can I run the tach wires from my FlightDek 180 straight to the tach wires on the back of the P-Mags? Should I include diodes in the lines?

ColinG: I have the same setup on my 0-360 Lyc and a D-180. I ran the tach outputs directly from the P-Mag tach outputs to the D-180 tach inputs, no resisters. Works fine with ACS ignition switch. Dan.
