Hi, Im not sure how to start a new thread here but this is along the lines of my question. I'm helping a friend Rich Adams with his AFS-5600 in a Sportsman. We just finished the SV 261 upgrade. He now seems to have a 2nd rpm sensor failure in about 30 hrs with Slick mags. Looking at the install manual for the EFIS it clearly shows no mag sensor but ignition switch connections to pin 32 and 33 for L & R mags with a 30K resistor inline of each shielded input wire. Is this the proper way to eliminate the mag sensor issue? This is how my electronic tach is wired in my airplane and Shawn M stated that this would be an alternative to the mag sensor tach method.

Thanks for any help on this. Cordially
