Superjet has no spark, Maybe cdi?

[yamahahaha]

Last year my superjet had no spark so I replaced the coil and plug wires and nothing, then I replaced the stator and still nothing and that was the end of the season so I put it in storage. Now Id like to have it ready for summer. Must be the cdi if its not the other two things right? Also I am wondering if anyone can help me in finding the right cdi for my ski. Its a superjet whith a 760 engine in it (cant remember what the engine came out of) the crank case has a little white sticker that says 64y on it. If I need more info off my ski to find the right cdi for it please let me know.

Thanks!!!!!!

Did you ever try disconnecting your stop circuit ( black n white wires connector) that's near the ebox ?

No I didnt, so there is just one black and white wire near the ebox? or is it two wires one black and one white? and do I just disconect it outside of the ebox and try for spark again? sorry i dont have alot of experience working on this kinda thung just know the basics but would like to learn so I dont have to always bring it to a shop Thanks!

The black n white wires (two seperate wires) go in and out a single black connector, you have to push a tab that's inside the connector, outward while pulling it apart. You will see connector less than a foot from going into ebox. Once disconnected check for spark, this rules out a bad stop switch. Note: ski will not shut off when this is disconnected.

If it is your start switch start here before you run out to buy another one.

your main ground cable could possibly be fried. if all else fails try running a small second ground from battery to flywheel cover.

followed the black and white wires from the ebox to the tubing where it goes into the handle pole and did not see a black connector but there was two seperate green connectors (one for each wire up at the nose by the handle pole. I disconected those two and still no spark so Im going to try finding a ground wire to test, anyone know how large it needs to be? can I just test it with a small wire? Thanks

yes test it with a small wire with good connection. i would leave the start stop switch unplugged just in case.

ok I tested with a small wire with clamps on each end, I clamped one end to the negative on the battery and the other end a bold on the fly wheel cover, did a spark test and still no spark. Last thing I can think of is a bad cdi right? Does anyone know how I find one right for my ski? Thanks.
PS I left the real ground wire disconnected from the battery when I tested with the small one because I wasnt sure if I should be leaving it connected.
