Hello my name is ***** ***** I will assist you. The problem here seems to be either coming from The safety lanyard switch or from the ignition switch. What i suggest you do is to open the control box and check these switches as most probably one of them is the problem.

If you need further assistance let me know.

Ok but where the safety lanyard switch is located. Since I have two motors I I already test the ignition switch by interchanging wire harnesses.plese tel me if by grounding brown wire from stator to power pack for a split second it's bad for electrical sistem?

to refresh my question for a1989 Yamaha 115 hp 1.75 Lt.problems getting start the engine it turns no sparks on the ignition coils...onse starts its good for a few days..after that no spark on ignition coils again..
Marine Mechanic: Kenny O., Personal Watercraft Specialist, Kawasaki Jet Ski, Yamaha Wave Runners, Sea Doo Watercraft replied 2 years ago

OK, thanks, ***** ***** if I'm wrong, you stated that that you ground the brown wire, if that how you get it to start or something else ?

Customer reply replied 2 years ago
Hi Kenny yes the only way I can get it to start is by giving a little bit of a ground to the brown wire that comes from the stator to the power pack.ones I get it to start like I mentioned it will be ok for a few days as long I keep starting it every day.thanks looking forward to fix this problem.
Marine Mechanic: Kenny O., Personal Watercraft Specialist, Kawasaki Jet Ski, Yamaha Wave Runners, Sea Doo Watercraft replied 2 years ago

Javier that really doesn't make sense, (not that I'm questioning you) but that is really odd, the brown wire is part of what they call the "charge" coil which I refer to as the exciter coil, this is the coil that charges up the CDI for ignition, by grounding that wire it would interrupt the charge to the CDI. So I'm going to give you some spec's so the next time you go to start the unit and it will not start I want you to check resistance on the trigger coil and then the exciter coil. You might have already tested the resistance on these coils, but what I would like from you is a dynamic reading (checking for AC voltage out of those two coils) I will post up a PDF file and if you can get some results back to me then we'll move forward from there, I have something else but I want you to try this first.

Thanks Javier !

Kenny

Give me a bit here and check back in about 20 minutes
