Ok as stated no spark.Wiring harness is clean.

I need ohm specks on the cdi box and I am 90% sure the stator is fine.
The coil is 100% working.

Any other suggestions?

I don't think there is a test for the CDI box. I think the only way to tell if it's bad is to replace it with a known good one. Someone correct me if I'm wrong, but that's what I've always thought.

I think your right.

nope..you can in fact ohm the cdi out..as long as you got the spec's for it..which i don't have handy..i keep my shop books at the shop..lol..but..yes..you can check them by ohming them out.

I've looked in all my repair manuals and none of them list any specs for the CDI and the only checks listed are for the CDI plug on the harness side.

You are correct Helmut you cannot ohm the CDI Im looking at my book now it only states to disconnect the CDI unit connectors and perform the circuit inspections. you can only test the components that lead to the CDI!

 

[shadetree]

i stand corrected..your right..it's the leading wires that it checks..my bad

hey i have the same can you help me

Hey, new here to the forums, but ive got the same problem. ive tested all the connections, i have the neutral and reverse light. i just cant seem to get power to the stator. So im guessing its a cdi issue? Anyone know where a good place to get one is? Thanks sorry dont mean to hijack your thread

Yeah, my money's on the stator or pulse generator.

What do you mean you can't get power TO the stator? The stator is the part that generates the power.

i been racking my brain last day or so trying to figure it out

 

[RedHotGMC]

yeah sorry my lack of knowledge got the best of me. I meant the ignition coil, but yesterday i took the stator off and compared it to the other stator and the one that was on it is pretty bad and im positive thats what it is. Im going to try and switch them out today. Although getting the old gasket off of is a pain in the a$$. Think i would be ok with a high temp rtv gasket maker? I plan on using it, i already checked and its ok for the conditions it will be under.

Hondabond would be better because it doesn't cure rubbery. RTV sealant will work, but just barely spread a thin layer on. If you put it on too thick, it will squeeze out on the inside of the engine and when it dries it will be rubbery. If it breaks loose on the inside of the engine, it can stop the oil pump up. I learned that the hard way. You can get Hondabond at your local Honda dealer and it costs about the same as a tube of RTV sealant. If you decide to go with the RTV sealant, just put a very, very thin layer on.

k will do. when i took the gasket off it was so glued together i had to take a sharp edge and shave it away, so ive got some gouges but i took a file to it and made sure it felt smooth.

ok..i'll try not to make this a long thread on this issue..but..here goes nothing..lol..first off..we'll start with the battery..if it's good...you turn the key on..you get lights on your green light...ok..we got power..now..if your starter relay is working...when you push the start button..it turns the motor over..as your motor is turning over..your flywheel is too..now..on this flywheel..you have a little piece of metal that rotates around...and it passes a thing called the pick up coil..when this pick up coil times all of this in a rotation process..which tells the c.d.i box that the piston is at tdc < top dead center >..it sends a signal to the spark plug coil to fire the spark plug..if any one of these is bad..you will not get fire to the plug...the 4 main parts to getting fire to the spark plug are c.d.i...coil...pick up coil..and stator..now..your wondering why your getting power to your lights from the stator..but not your spark plug by now huh ?...i'll tell you..your stator has to sides to it..one side sends fire to the c.d.i and spark plug..while the other side of your stator sends power to your reg/retifier...which means..you can get power to your lights and so forth..but no fire to your plug..soo..in case your racking your brains out..trying to figure out why your lights are workiing..but your not getting fire to your spark plug..now you know...hope this helps.

any update on this problem?i have changed the coil and cdi,no spark.guess the next will be the stator.how do you test the stator first????

you can ohm it out..i don't know the spec's..but..unplug it from the wiring harness..should be 3 yellow wires that go into a round plug. other than this check, i don't know any other check to see if your stator is bad..now..you can check to see if it's working your lights..unhook your battery ..postive side, kick start your bike..watch your nuetral light..if it glows as you kick it..at least your stator side for the battery is fine..also..i'll throw this in..as if i remember right..those atv's had a resistor inside the end of the spark plug boot..look's just like a slow blow fuse..check to see if you have one ??..if so..keep the spark plug boot off..with just the bare spark plug wire near your motor..crank your engine over..does it fire then ??..if so..if you have that fuse thing inside your spark plug wire..thats your problem...edit:..would like to add..make sure your kill switch is on the '' run'' position !.
