no Spark again

[snowman]

buddy has a 2009 600 switchback , every year he brings it to different shops to find the cause of no spark ,they changed stator , coils , cdi ,plug wires plugs. plug caps , parked it last year with it running like a champ , now no spark , this is a EFI does it need battterie power to have spark ? or is it the same as the older carb version that did not require batterie power

No, no battery required. If its EFI there is no CDI?
The spark is controlled by the EFI computer (ECM) and there is a capacitor in the system that gets charged off the magneto when you are pulling it over that powers the ECM up thru the voltage regulator.
My guess would either be the voltage regulator or capacitor. The voltage regulator in those years was known to be problematic.
I've also heard that the ignition switch could also cause weird issues if water has gotten in there and caused corrosion, might try unplugging that and see if it starts.

can anyone tell me where the capacitor can be found on this sled

Its piggybacked on the voltage regulator, which is in the clutch cover above the primary. See my response here for more info.

2012 Polaris shift IQ 600 problem

I have a new to me 600 shift iq. While riding today the sled’s digital display went out and the machine killed. It will restart and run for a few minutes but then the same thing happens. Anyone know what could be the problem?
