my ski wont shut off!!

[grunty13]

so i start my ski.. the stop button doesnt turn it off.. the lanyard pulled out doesnt shut it off. i even pulled one of the spark plug wires and it didnt shut off.. than i tried the stop button again and it finally stopped

i dont get this. any help out there for me

 

[Matt_E]

In the water or out of the water?

 

[grunty13]

it happened in the water and finally stopped one time before.. but this just happened out of the water sitting on a stand

btw its a sj

Have you cleaned the contacts? If your SJ is set up the same as my SX, pulling the laynard and pushing the stop button does the same thing. Actually, all pulling the laynard off does is push the stop button.

Start by checking the connections, then open up the switch and check it out, if those aren't the problems, well, something is wrong in the box. Contacts corrode over often if your riding in salt.

You ski can run on one cylinder, so pulling off one spark plug wire isn't going to kill it.

Weren't you asking this same question a few days ago? I recall someone asking and they were told to clean the contacts in the switch. Was that you? Did you clean them?

 

[The Penguin]

you can shut it off by choking it if your switch is not working.

 

[john zigler]

clean the contacts, like stated above. there is also a "pin" in the middle of the button to stop it from travleing in too far when pushing it in. ( to stop). we file this pin some to alow the button to go in a little farther and make better contact.

no that wasnt me but maybe i should check that thread out haha

good call and choking it out i will remember that.

i think im gonna pull the start/stop switch apart and clean it out and maybe check the connections in the box

I don't think you need to pull your box apart if it was properly sealed. It wont hurt to do that, just means you get to silicone it all back up again.

You'd be wasting a lot of time if you pulled the box apart everytime your contacts got a little corosion on them. The way it works it a little metal square touches anouther little square in the switch, and that lets the power flow to the box. Everything past pushing the buttons is hard wired. They very rarely have a problem. What has a problem is those little quares get dirty and then can't connect. You don't have problems in the box because it's always connected.

Be careful not to damage the contacts when you clean them. You can use a contact cleaner, and if they are really dirty, you can use the sand paper on a match box (the paper match boxes that have a super fine grit paper).

better off using a flat blade (knive or screw driver), scrape the metal disk.

I would not open the box until last resort.

the YAM lanyard button is different design than the Kawi.
seperate unit

It's a yamaha the contacts for the S/S switch are external right outside the box and the yamahas use a rubber gasket so silicone would essentially do nothing on it.

Grunty, you mentioned it wouldnt turn off even if you pulled the spark plug wires off, now i'm going to assume that happened out of the water (where it wouldn't shut off by pulling the plug wires) and if thats the case then did the motor start reving up by itself or idle really fast? If it did it sounds like an air leak also. THe connector for the stop switch are the black and white wires and they have a black plug, they are right outside of the electrical box on the right side of the ski pull em apart and see if the contacs inside look greenish or if their a little chitty. Spray it out with some electrical contact cleaner and be careful if you use any kind of tool to clean them because they are flimsy and you can break the contacts.

When checking the contacts just outside the box (as ANT mentioned), put a multimeter on them and set it to ohm's. When the button is pushed you should have zero resistance between the two pins of the leads coming from the stop switch. If that checks out you know your problem is not within the switch itself.

Thinking Air leak,This may sound wrong but it work's, , If the motor races on you again pull the throttle wide open till she stops.

 

[Matt_E]

He said it was in the water. And that he pulled only one plug wire. And that the button started working again, shutting it off.



Pretty much eliminating the air leak theory.

this happened to me the other day when my steering plate clipped the wires for my startstop switch

This happend to me with my ski on the trailer. I always start it up before I back it in the water with the hood off. Once started, it just started climbing the trees and was out of control. Nothing would stop it. We finally stopped it by pulling off the air breathers and putting our hands over the Carb's - smother the sucker. For me, it was an air leak which was causing a very lean condition. The spark plugs get so hot that they keep working. Everything in the electrical system worked just fine. I wouldn't think that would be the problem if it did it while in the water. I never had this happen to me while in the water. The drag from the prop kept it from climbing the trees.

Check your spark plugs are they white, brown or black? If they are white or gray color, I would say you have a lean condition and it needs to be checked out before you ruin your motor.

pull the throttle full open, that kills it also.

^^ Quickest way to kill the runaway is to simply hold the stop button and hold the throttle widen open.
