Thinking I got a stator problem.....do I have to pull the engine to get the stator?
So after doing some troubleshooting through the service manual and some searching here on the forums, fairly certain I have a bad stator (or CDI) on my 95 SLX 780 (awesome ski btw).
She's been a champ all summer, hit a big wave out on the lake Saturday evening, came down and engine died.
I'll give you the symptoms if anyone wants to chime in on the possibility of another issue I'm all ears (and I did check to see if anything got sucked up into the intake, looked clean).
I'll be doing the resistance test outlined by K447 found here a little later tonight, I'll post results:
Like I said, after coming down from a particularly big wave she died. Engine wouldn't even crank, just the starter clicking. Got towed in (friggin mile off shore on lake michigan at 7:30 at night....thank god I had a radio with me) and got it back to my garage.
Checked the battery, voltage was fine. Electrical box was dry, no blown fuses, no visible corrosion or shorts in the box or on any visible wires. Pulled the shaft shroud and when I hit the starter the shaft would turn about a quarter turn then stop. Pulled the plugs, none of them had spark.
Assuming the worst that this is the stator. I'll test to know for sure. But my main question is....do I have to pull the engine to get to the stator? Procedure doesn't looking to difficult (the write up anyway), just no mention of the logistics of actually getting to the front of it.
Guessing I have to pull the thing huh?

i know that sometimes the stator cables run through underneath the engine sometimes people come off a wave and the engine sumtimes crushes the wires maybe not, heard this happening beforeto someone i know, its easy to get into just takle the gas tank out and you should see the front casing take this off and you will see the flywheel carry on to take the fly wheel off with a puller and you will proceed onto see the stator then carry on from there

Here are the resistance testing results. Thinking it's not the stator....
Red/Purple to Yellow - .6 ohms
White/Yellow to Black - 215 ohms
Blue/Red to Red/White - 88.8 ohms
Red/White to Green/Red - 457 ohms
all seem to be within +/- 10%
anyone have any suggestions? can some clarify the process for testing ignition coils.
I understand the black to black/white
but can someone elaborate resistance testing on
"Black to secondary lead" and "lead side to spark plug side"

I would pull the pump and driveshaft out ( leaving the pump shoe fastened to the hull) and try to turn the coupler by hand with the plugs out, If it doesnt turn then I would pull the motor.

You are saying the engine doesn't even "crank". Does that mean that the starter is not even turning the motor over? Your ohms test was good so it is most likely not the stator but it could be the CDI assuming that when you are saying "crank" means that you are just not getting any spark. I had this issue and just had to change the CDI. I did an ohms test as you did and found my stator was good and purchased a stator/cdi set and then just used the CDI. The CDI and stator must match so I just made sure I had the same part number when I pulled the bad CDI from the electrical box.
If your issue is that the motor will not actually turn over then you have another issue going on.

sorry....tough to describe sounds in words.

Please clarify for me: (no noise sounds please)
Does the engine turn over when you hit the start button?
What's your battery voltage when cranking?
Do you have the plastic cover between the battery and elec box?
Is the ground wire connections clean and tight? (battery and engine plate)
Have you checked the jet pump for an obstruction?
