I have my tach wires as hooked per spec. They are hooked to my p leads on a 0320 lycoming.
I also installed the 30 k resistors as shown in book. I noticed when I was spinning up my motor for the first time to pre oil that my tach was junping from 0 to 5186 or something like that. I did not have plug wires or plugs in engine at the time, nowhere to discharge spark.I also have the the revelotion to 2 in set up .Is this what would happen?? . I havent cranked engine yet.
