Hi, I am wondering if any of the bad Simplex coils were shipped to the US as I am having issues with mine , it will false while sweeping over thick grass or the slightest bump on the ground. It will VDI 93 or close when it falses. I checked the connections and routing but it still happens. Sometimes it will work properly for a few minutes and then return. I am really happy with it other than that. Anyone else experience this behavior with their Simplex? Thanks!
