  • Yamaha 2004 SUV no Spark

    Ski has always started right up and ran great even as of yesterday. Take back out today and wouldn't start and has no spark. Literally sat overnight and no spark today. Turns over fine

    Battery is fully charged.

    Pulled Cover off electrical box and everything looks good....grounds are secure, no loose connections, no corrosion. All three spark plug wires have no spark after testing. This is as far as I got before reading a ton of forums and I didn't find anything directly related to the SUV.

    I know I need to start with testing something but not sure where to start.

    Will the SUV start with a bad Stator? And how would I test this?

    Can I do a test on the CDI unit? If so which wires and how?

    Do I need to test the rectifier/regulator? If so which wires and how?

    There really isn't many electrical components to the SUV.....just not sure where to start?

    Anyone have a wire diagram for the SUV's?

    I'm pretty handy with a wrench, but no so familiar with the electrical items or how to test.

    Any help would be appreciated!
