My daughters Eton Viper 90r just stopped running.... New plugs and air filter but still nothing. I was checking the arc on the spark plug and you can see it but it looks real weak. I was thinking CDI box or the coil at for the plug. Any thoughts?

Thanks
Dan

 

yeah CDI or coil are two things to check. also the stator. there's a test that you hook up an ohmmeter to your stator outputs and get the reading. there should be a specific reading for your machine, i'm unaware of it, i apologize. if that reading isn't right, then your stator may not be working properly.

however you mentioned you can see a spark. in that case the stator is working at least. i would test the stator anyway, then you can determine if its functioning correctly. if it is, then try to find a known good CDI to swap in the quad. then if spark enough to start, your CDI was bad, if no spark, the coil is probably to blame.

also, the killswitch system could have a fault, as well as the harness itself.

 

SundiroSunray90,

My neighbor's tether killswitch (which has never been used) somehow worked its way loose enough to not allow the bike to start. After about an 40 mins he was going over all the connections and found the culprit.

 

Thanks for the input... This quad does not have a tether kill switch. I am trying to figure out how to test the stator

 

here is a test to check the stator. scroll down to etondaddy's second post. you will need an ohmmeter.

[no spark on eton] - ATV Riders Forums - Honda, Yamaha, Suzuki, Kawasaki, Polaris, CanAm, Arctic Cat, Kymco ATVs

in fact, you have an eton as well, so the results should be similar.

 

Hi all. My little boys Eton 90 will not start. I am thinking it may be the gas or possibly a kill switch. I bought it from someone and do not have the book. Can someone please help me identify where the kill switch is? Thanks.

 

Does your eton 90 have reverse? The wiring on the reverse equipped models is quite a bit more complex than the non-reverse models.

You can download the manuals for eton quads for free at www.anythingatv.com. You can also download just the wiring diagrams, though the diagrams are also imbedded in the manual so I'd recommend just getting manual and printing it out. There are some troubleshooting guides on the anythingatv site as well.

First thing to check:

Do you have spark? Pull out the plug, hook it back up, and hold the threads against the engine block while cranking the starter. Look for spark at the plug gap.

 

Thanks for the info. It is getting gas and there is a spark. I will print out the manual and work on it when I get home. If I find anything, I will post. Thanks.

 

anything atv has pictures and instructions and the specs for testing coil stator etc as some one has already mentioned look around on the site pretty useful

 

Is the spark plug wet?..If not try putting a splash of gas in the carb (with the air filter removed for access) and see what happens..The carb may be getting gas but that doesn't mean it is getting into the engine....The spark isn't overly big on these anyway so that may not be the problem...I replaced the stator on our viper last year due to a weak looking spark and it turned out to be a non related problem that was causing my issues..
