Hello!
I have a 2005 Polaris 500 ATP with no spark and no electrical(headlights, speedo, anything). If you jump the solenoid it attempts to turn over but there is still no spark. We have checked the wiring and aren?t able to find any shorts or bad grounds. New spark plug. Coil and stator appear fine. Thinking it may be the ecm. Unfortunately this model did not qualify for the ecm recalls for 2005s. Parts # on the ECM is 4011085. Is there a better way to test the ECM? Or any other thoughts as to what the problem could be? It looks like it?s a $400+ dollar part so I hate to shell out for that without knowing for sure if it will fix it.
