350X no spark

[QCR77]

i was messing with a new switch last night and today i checked for spark to find none. what is it in the case on the left side? alternator? if im gonna spring for new stuff to get a strong spark i'd rather go after the most difficult thing first. any help welcome

[QCR77]

so it should be one or more of these components-

ac regulator
cdi
ignition coil
pulse gen
alternator

i just put a new regulator on it, is there any way to rule out a couple other ones? also, which one is the stator? its not metioned in the manual

Electrical troubleshooting starts on page 16-1 of the service manual.

Weak or no spark, page 17-1.

its not an alternator, its a stator. difference is alternators are external stators are internal, they work a little different but do the same thing too

[QCR77]

is there a way to test the pulse generator and stator ?

[Mr_RPM]

resistance test, you need to find the resistance specs and test the coils, but if you can get your hands on a cheap parts bike and swap around then thats the easiest way

[QCR77]

i got a tester tonight and the ignition coil came out to .3 according to the specs it should be between .16 - .2
also tested the cdi and it didnt even give a reading on most of the tests. others that did give a reading werent up to the params
anybody have any experience with testing these things?
is .3 ok on the ignition coil? with the cap off the end of the wire was in the params
is the cdi obviously shot when i dont even get readings on most of the tests?
if it the cdi, it went out while is was hooking up a new switch and getting the headlights to work for the first time in a while. does that make any sense?

I've got the same prob right now and wondering why we can't simply use an external 12v source to compensate for the stator output.

All the things I've read, they work, or not, have ohms, or not, throw voltage, which may look good but not be enough to fire the ignition.

Are you trying to run this with that TRX switch you rewired? Maybe you should try the old 350x switch and see if that works? I hope you didn't wire something wrong. You did say the 350x switch worked for off an on but just not the lights right? Go back to what you know worked first and see if it will start. Then we'll go from there. Start with basics and work to the harder stuff, not the other way around.

[QCR77]

i'll try that vealmonkey, but shouldnt it get spark without any switch hooked up at all? i just wish i knew how to make sure my stator,pulse gen and exciter coil are working. the internal stuff ya know.
i'll go hook back up the old switch and see what happens

[Vealmonkey]

You can bypass the switch, but if she sparks with the old switch then I would say you wired something up wrong my friend.

[QCR77]

i tried to wire up the old switch but before i could the green ground wire came out of the switch. where its soldered in there. so the old switch is gone and done with. from what i have found out it should spark with no switch and it doesnt. could i have shorted something by hooking up the new switch wrong, absolutely. thats what im convinced happened. i just dont really know what im doing when it comes to testing all this stuff. i dont mind buying a new cdi, but i just dont want to get it and then find out something in the case is messed up

[Vealmonkey]

Man, do you have a soldering iron? Get busy. You are trying to find out if you have spark. You can order another switch or buy another used switch on ebay. That doesn't cure the here and now though. I can't believe you are giving up so easily. All your methods are not exhausted yet. And I don't have the wiring diagram in front of me here at work, so I'm kind of blind as to what's going on now.

this is exactly the series of events-
i got the new switch hooked up
i started the bike and tried the lights, nothing
i tested the kill function to the right
started it back up and tried kill function to the left
no problems with starting it or the kill function so i focus on the lights.
i cant get anything to work bu then i press the horn button on the switch and they go on while i have the button depressed
i do this a couple times but it doesnt work every time
so i turn the bike off to try and rewire, but it never started again

coming out of the left side of the engine, test between the blue yellow wire and the green white wire with your meter. should have 297 to 363. that is for the pulse generator.
