750 sx NO SPARK

[N3vrSat1sfied]

I know this has probelly been discussed before i just searched though all the related searchs and couldnt find the answer so here it goes

750 sx was running good and then at the end of the day when i went to start it to flush the salt water out, It would not start. I got fuel, air, and good compression. I mean i was just riding. I pulled the plugs and got nothing no spark at all that i can see anyway.
I pulled the E box apart to see if it was possible wet or had a lose connection looks good. Battery is on the battery tender it wasnt fully charged when i tried this but it was turning it over just fine.
any advice???

Stator, Ign Coil??

start stop switch bad?? This happened to me on my blaster.

bypass the start stop switch and see what happenes

 

[N3vrSat1sfied]

Wouldnt the start stop switch not give power to the starter really though?

It still turns over and trys to start there just isnt any spark.

The last time i had a start/stop switch go bad on my 650 it would not even let it turn over.

Its probably the stator.

 

[N3vrSat1sfied]

Thanks wedo for the input. The stator is one of the cheapest things that could be creating the problem. So i might start by ordering one.

Usually the spark intermittently when the stator goes bad,check it tonight when its dark and see if you see any spark at all.

 

[N3vrSat1sfied]

I just checked it and there was very little spark the very first time i hit the start button. then nothing. I waited a little while and it tried it again the very first time i hit the button i had spark but its very weak and hardly noticable.

i would check the start stop switch and the coupler near the e-box. those connectors are for poop.

If the start stop switch had a bad connection then wouldnt it not be powering the starter relay and the engine wouldnt turn over

check all the connections in the electrical box too. i spent at least a week tryin to find out why i had no spark and when i opened it up it was like oh, duhh. :doh:

Yea i just had the ebox apart and everything checked out as far as connections and everything was dry too

also rather the starting a new thread and since this is a 750 kawi thread anyone know how to hook up the cooling lines on a coffman system. I just ordered one.

Its probably the stator.

Vote #2 for the stator.
As with any electrical problem I'd check all the connectors first but after that I'd say stator.
I went thru 2 or 3 stators in my 750sx back in the 90's. Kawasaki had problems with them back then.

not true. if the start stop switch went to ground then you would not be getting spark. It would still turn over the motor.
If your gonna argue about advice then why ask?

I was simply asking. to my understanding i thought i wouldnt turn the engine over. I have another start/stop switch i can go tryit jst doesnt have a teether.

Yeah you can go into the electrical box and unhook the ground wire from the stop switch or hook up the other switch,that switch is the same the tether was just an add on feature.Try one of those first as the electrical troubleshooting process is always eliminate the simple stuff first then go into checking things with the volt-ohm meter then replacing parts,regrettably there are not many checks you can do on the stator.:ugh2:

right the two switchs are the same minus the teether. i can just hook up the other switch like you said and see what happins the 750 just has that plug in connection to so that makes things easy, i ll just have to pull the ground

this is how my dads is hooked up

you could test the resistence of the stator to find out if its bad or not. Mine went bad on my 93 750sx. Heres the numbers

blue/green=540 ohms
red/purple=450 ohms
brown/brown=2 ohms

if you find that your stator is the problem, call John at Jetskisolutions. He will rebuild the stator for $120 bucks and you wont have the '92-'95 750sx stator problem anymore.
