Ok, You are going to need to test the electrical system of the ski. You will need a DVA meter a compression tester, and an adjustable spark tester. Can you get these items?
Customer: replied 1 year ago.
Ok I have those ots just a matter of what to check?
Expert:  Charles replied 1 year ago.
First check the compression of the engine. It should be over 100 PSI and with in 15% of each other. Then do a spark test. If you do not get spark on all cylinders, locate the plug coming from the stator. Disconnect it and test for cranking voltage from it.
