94xp fires only while starter engaged

[crashcourse101]

OK, I have recently purchased 2 94xp 650 one of them was said to run. It only gets spark while starter button is pressed in ?? wont run or idle when button is let go of. any ideas? something I could be looking over? I am guessing it is something simple.

While holding the starter the ski has spark and will run but as soon as you let go the spark dies. Besides the lanyard is there any specific key or security device on the 94xp? There is a yellowish orange plug or something toward the front of the motor with two open pins what is this for? Anything to do with my problem?

The other one was said to have the oil pump go bad. The guy did not know condition of engine but it does turn over good when there are no plugs in it . I have taken the oil pump out of the equation in both skis . From what I hear there have been alot of people with too much or not enough oil to the engine. I would rather mix it myself and know.

These are my first skis and the first two strokes I have played with.

Tether cord...

Sounds like it may be your tether cord switch. You have three switches that control ignition, that all have to work with each other for the enging to run. First switch in line from ground is the Stop switch. When this switch is closed, it grounds the ignition, shutting it off. The tether switch is a safety switch on a rope (tether) attached to you in the event you get thrown off, it will also kill the ignition. The other switch is your start button. It works. You can turn the engin over and it will run. So, it's funtion is o.k.

One of your other switches, I'm gonna guess the tether switch, is bad. Expose the tether switch from the connection and get a jumper wire, jump the two wires from the tether switch and try it. Then, try it without the wires connected. Then, do the same to your stop switch. One of those two aren't working.

That yellowish orange plug is your grounding lug. It's where you put the caps to your spark plug wires when your working on the ski. It grounds the ignition system to allow the coil to discharge.

You probably want to get yourself a compression tester and check your cylinder compression to see what condition the pistons are in before dumping to much money in them.

thank you I will do that tonight when I get home and let you know the outcome...

nothing

i tried to swap switches from one ski to the other....hmmm what are the chances they are both bad .

it just doesnt make since i looked over everthing and still same thing it will only run and rev while i am holding the starter in . the spark just dies out ... what keeps the fire going to the plugs after the motor is running?

do you have any other ideas?

i don't think these have a wire from solenoid to ignition to give hotter spark when cranking like old points-type automobiles did. the start button should only fire the solenoid. ok, here is a possibility. the red hot wire is mounted on top of one big pin on solenoid? make sure it is on the one that is hot all the time, not the one on the starter side of sol.

 

[crashcourse101]

Sorry, but you are talking about inside of the grayish box where all the wires lead too the (red) hot wire from battery is going to a solenoid? and out on the top other side of solenoid ? correct ?

 

[crashcourse101]

still need help

I swapped the entire brain box jumped the teather switch still same result.

Is there any other grounds besides from the starter to battery?

could it be something in the starter?

Switches....

No, if your PWC is still wired the way the wiring diagphram says it should be, then you got a bad switch or a short.

The stop switch runs to a ground. Take your stop switch and disconnect the ground, then give it a try. Keep in mind, if this works, you'll have to choke the engine to shut it off.

Like derek says, back in the old car ignitions, there was a wire going from the starter solenoid to the ignition system, when the starter was engaged, it would supply power to the ignition and the car would run. But only while the power was engaged to the igniton. This is similar to your problem, but it's because you have one of your switches that want to start, and one of them wanting to stop.

 

[crashcourse101]

Could it be possible ....like you are saying, but its not getting a full ground at the kill switch and when the starter is engaged the ground is full but when released it kills the semi contact at the switch and does kill the motor...?

Thank You

I just want to say thank you to all of you who helped me ...

Not sure what it was but Ha I jumped the starter to the batter while it was diconnected from the box. holding the button thinking if this works well there is no reason it shouldnt run.
So, It ran I plugged everthing back up and fine works great ...

Took it to the lake dropped it in half way it almost pushed my truck up the ramp, with no issue. wooo hooooo:hurray::cheers:

Is there any other tricks I can learn that you guys may be interested in sharing?
