    98 gp1200 electrical woes

    so a lot of you have commented on my last post in an.effort to help me figured i would start a newe thread with a more relevant title. I have ohm tested my stator and everything checks out to manual specs, installed a new battery, ran through my entire wiring harness and found no issues yet i still have no spark to any of my 3 plugs. it was running perfect one day and just died in the middle of the lake the next, seriously i would rather rebuild a top end than search for and electrical gremlin. my next move is a new CDI, can anyone guide me in the next direction? im familiar with the seadoo 951's and love the simplicity of the 65u but i hate electrical problems. i have read every thread on all the forums out there and this problem is usually fixed by a new stator but mine is ok?

    thanks again in advance!

    ill take a look at the switch, what is the best way to test it? pull/jump the plugs and crank it? thanks again for the replies, you guys are the best.

    Disconnect the black and white wire that comes from the stop switch on the handle bars. REMEMBER that with this disconnected, you have NO WAY to stop the engine unless you reconnect it....otherwise, sounds like a CDI,, going thru the same thing

    Pull your harness connections apart as well and look to see if any of the wireing has burned up there. I believe the 98 also has a code that must be entered to restart the engine. Did you re enter your code?

    the thing that points me away from the killswitch or the code is that the engine will crank over fine, it just wont send a spark to the plugs. ill run it all over tonight when i get home from work. and yes, i have entered to code to lock and unlock the ski.

    There are different parts of the switch for the starter and the ignition system. In particular, the "stop" button has nothing to do the with the starter...it kills the ignition. Its tied into the lanyard switch and uses a different part of the lanyard switch then the starter does.

    disconnected the killswitch, no luck i guess im after the CDI, can ohming out the stator really give me an accurate diagnosis on its condition, how reputable are those tests?

    The stator ohm test is a pretty rock solid test from what I've seen.
    one last thing to check is the thermo switch.
    There is also a ohm test for the CDI, if I remember correctly.
    Maybe double check that stator? Its almost always the culprit
