starting to get to the pointy bit of wiring, how does the 2500 analog module interface with the Rotax 912 tach signal wires.
The 912 can be interfaced to the 2500 using our 71,420RX RPM Interface board. Call us at 503-263-0037 x 2 for ordering.
The Rotax engines have a 5th trigger coil for RPM monitoring. The trigger coil outputs on a two wire harness. Connect one of the two wires to ground and the other to the supplied 33Kresistor, the other end of the resistor than connects to the P/N: 71420 R Rotax RPM interfaceboard yellow wire. The Rotax RPM interface board is a small heat shrunk module and shouldbe secured on the inside of the aircraft. If you are using the P/N:71420RX you do not need toinstall the 33K resistor.
