Blaster ski doesnt always stop

[Jpass]

On two separate occasions now my ski ('93 B1) will not stop when u hit the stop button or pull the lanyard. The only she will stop is if I pull a plug wire. It is intermittent at best and has only happened twice since I got the ski a year ago.

My concern is that this will happen after I fall off or someone else who's riding it falls, then the ski will keep going.

I have replaced the connectors leading from the switch to the ECU. Should I just get a new switch or is there someplace else I should be looking?

The ski will always start by pressing the green starter button even when the kill switch and stop button are not responding.

Ideas?

clean the contacts on the switch, or swap it out with a good one.

are you talking about when its in the water or on the trailer

It's a bad stop circuit. It's either a bad start/stop switch (usually a cleaning will fix), broken black or white wire, or black and white wire connector near the e-box is bad.

eventually I finally bought a new start/stop switch from yamaha for my ski.

if its when its outta the water you proly have an air leak my old one would do that

it does it in the water mostly. That's how I usually find that the switch isnt working. Then when i get it on the trailer, it still doesnt work. Then after I leave it for a while (during the week while it is in the garage) and go to restart it, she works fine 99% of the time.

I have yet to clean the contacts, so I will try that. I have not replaced the stock connector yet either, so I will try that if the cleaning doesnt work. Any ideas on what a replacement start/stop switch runs?

When it is not working, the start/stop does nothing at all, but the start button works fine all the time.

Mine did the same thing and it ended up being the cdi. I had replaced my switch and it kept doing it then i replaced the cdi and havent had the problem since.

I cleaned the contacts and replaced the connectors and so far so good, everything works fine. If it does it again, I'll let you know.
