2003 summit 700 zx PROBLEMS

[hark07]

I have had my 2003 summit 700 to three different skidoo dealers and no one can seem to fix it. The skidoo will idle for ever until you bring the rpms up.... as soon as you do it fries the mpem and you need to replace it. I have spent over 3000.00 on this and it is still not fixed. it has a new wiring harness and four new computers.. please if anyoone has ideas let me know.

sounds like the voltage regulator is shot. Any problems with lights etc?

That is the funny thing all the lights and every thing work great..... It has everyone stumped

I'm guessing nobody has checked the output on the stator. I believe the stator has two separate charge circuits....one runs accessories and the other for the ignition. Doo stators have never been the most reliable things. Never heard anything happen like yours mind you, usually they just leave you stranded with no spark.

So, was the VR changed?
