Js300 will not get spark!

[DustinJ]

Ok I've searched all over so please don't tell me to search. I have new cdi, new spark plug eveything. Is it possible for the magneto to go out and would that cause no spark to start? Thanks, Dustin!

 

[steve-uk]

have you checked the relay and coil?

 

[DustinJ]

Well I know I'm getting negative power to the coil but how do you check it coming out? Basically how do I check the relay and te coil? Thanks

its gotta be your stator

Ive got a good stator if you end up needing one.

Sounds like a stator thing.
I only know Yamaha, but resistance checks are the way to know for sure. If you can find a service manual for your ski, then you should be able to find those resistance specs.
Otherwise, you're "parts swapping".

I've had folks tell me I had a coil issue....a stator issue....a cdi issue.....
Ya just don't know til ya check.

BTW: js300?

 

[DustinJ]

Yea kuz it turns over just fine it just doesn't have any spark.

 

[DustinJ]

Ok the coil is good I just checked the resistance. What else can caust the spark problem?

 

[poopski]

Check the Start stop switch! Open it up and disconnect the stop portion and check spark again! Let me know if you need any parts I have everything, e-box, stator, coil.

Ok so it looks like it's te cdi igniter that's bad. Anyone jaw one? Or a good whole electical box for a $300?
