1994 WRA700S Waverunner Questions...

[Lizzy K II]

I was using my jet ski last weekend and it ran great. It got flipped and it was turned over and it ran fine. About 10 minutes later it slowed down and died and wouldn't start again. I brought it back to the hous and found that I wasn't getting any spark. I read some older posts on this jet ski and I tried to disconnect the kill switch but I dont know where to disconnect it. I took the handle apart and it looks like 4 wires are molded directly into the back of the kill switch. If anyone can tell me where to disconnect this it would be a huge help.

I am a little leary of the problem being the kill switch because when the lanyard is off the starter will not even engage. With the lanyard on, the starter turns like normal. Could the problem still be in the lanyard kill switch?

I've tried to locate a service manual for this model of waverunner but the only one I have found is from yamaha for $80. Is there anywhere online that I can pay to download a copy?

I appreciate the help guys

Do you have an ohm meter ? if so post the wire colors going to the switch they should be universal . You can check the reading from kill wire to ground to be sure it is open .

Yes i have an ohm meter. There are 6 wires going into the back of the lanyard kill switch. There are two blacks, two whites, one red, and one brown wire. How do I disconnect any of these? Where do they disconnect? It looks as if all of the wires are molded into the bottom of the switches. The kill switch does have 4 small screws holding it together but I do not know the switch comes apart or if I would be able to get it back together.

As I said before, with the switch engaged the starter will spin, and with the switch disengaged the starter will not turn at all. Does this mean my switch is good?

not necessarily.

look inside the ski, find the electronic box - should be rectangular, black in color, about 5" x 10" with a round cap on it.

coming out of the side you should see 4 wires in one grommet, and possibly 5 in another. The 4-wire set is the one you should be concerned with.

There will be a black, white, red and brown wire. trace the 4 wires outside the e-box until you find a pair of plugs. One plug will have the red/brown set, the other is the black/white set. Disconnect the black/white set and try to start the ski (using the lanyard, of course).

If the ski starts, your switch needs cleaning, rebuilding, or replacement.

Since you unplugged your stop switch, you will have to either choke the engine to stop it, or use the primer and flood it it with gas to stop it. If you have any kind of aftermarket air filters, you can remove them from the carbs and use your hands to choke off a running ski.

I unplugged the black and while plug as you said and the ski started. I then plugged the plug back together and the stop button worked just fine and killed the motor when it was pushed. Again I tried starting it with the plug together and it worked fine. At this point I'm not shure what my origional problem was. I installed new plugs as well.

Is it possible this problem was due to a half dead battery and the jet ski not recharging it properly? How can I check to determine if the ski is charging the battery while running?

I'd guess that corrosion inside that plug was your problem.

perhaps bad connections at the battery.

take all apart and clean them and reassemble.

use dielectric grease inside the plug when you put it back together.

Since you are from Victoria, I'd guess you are riding in salt or brackish water - and can almost guarantee that was your problem.
