Hope this saves someone a headache,as I have learned alot from just reading all the posts here.Well here is the problem,my sons 2006 ski doo gsx 500ss had a difficult time starting last week.The was only 1 guy that could start this thing,he would pull it 2 times real quick without the motor(put new rings in beginning of the season so had good compression)stop spinning.The machine was hauled to a local dealer to be looked at,they told me battery was a little weak,but felt problem was in the stator or possible ecm.They used a test ecm, it test out fine so,eleminate ecm at this point.I asked the dealer can this machine run without battery, he stated that it could as there are non electric start units out there.Well after dying on the trail once, and not being able to start this thing without the help of the incredable hulk, I packed up and end the trip early.When I got home called local dealer, he said it pointed to battery.I put charging box on and it started,by switch or pulled 1-2 times every time.Put new battery in,everything fine now.The dealer in the UP was right it will run without battery, but as I found out it will not start.So, check the obvious things first,as I am left feeling stupid ,hope it helps someone else and saves your trip!By the way ,replaced with the gel battery not liquid,it should stand up to the vibration and not have cells short out so soon.
