Just curious, is there a wire connected to terminal #2 on your left mag? Also see if you can get the part number of your left mag? If it's 4373, it has an impulse coupling and to replace it with a Surefly you would nee SIM4P, not SIM4N.DerekM wrote: ↑Mon Sep 18, 2023 10:57 am Thanks for all the inputs guys! I’ll look into surefly, and why I was quoted $3k USD when spruce sells for $1270. I have the older SS, my plane is a 2003, so maybe the older one with 4 leads costs more. What lead me to disconnect the VIN (voltage in) lead is the breaker would pop when I tried to start the engine. Like I say, it starts perfectly well now the VIN lead is disconnected so it seems like my engine does have an impulse coupler as well. If I have an impulse coupler maybe I shouldn’t get surefly? Why change something that is working sort of thing.
Champion now has the SlickStart. Note that there is a very old sb (Unison Service Bulletin SB1-06) that retires the use of pin #2 to the point of cutting the pin off entirely. The ones Champion now ships do not have that pin at all. See Champions manual L-1492E. Lots of info on there.
