I have 2/1998 models; when switch is turned to run/start; one engages the FSS pulling it backwards; works fine. The other; when I turn on to run position; I have to take a stick & push it backwards & it engages & JD starts. Any ideas? Battery/alternator are fine; just checked ALL wiring & both are the same. I have 12V at least on the red wire @ the FSS & ground is good!!
