Posting this with hopes that someone can give me an idea on how the ignition unit and kill switch work on my 93 650 SJ so I can fix this problem.
So, I was out riding a few weeks ago and the ski died on me randomly. Plenty of cranking but no start. After about 5 minutes it finally started again, and I was able to ride for a little longer until it happened again. I took apart both kill switches (lanyard and button) and they both look brand new inside but cleaned the contacts anyway.
Back out to the lake and the same problem after about 30 mins of riding.
So today I grabbed my meter and an inline spark checker to figure out what exactly is going on and this is what I found:
Switch tests via the meter perfectly with the meter leads at the connector near the ignition box (should rule out any frayed wires in the pole). The ski starts and runs fine but once either the lanyard is pulled, or the kill button is pressed the ski will shut off and will intermittently not start back up. There is plenty of cranking but no spark until I after I try to start a few times. Every time I was able to get this condition, I would unplug the kill switch connector and the switch would test correctly.
Here is where it gets weird. If I have the motor running at a decent rpm and just touch the kill switch for a split second, the spark will not come back after I let go of the switch and the motor will completely die. This is when I experience the problem because about half the time right after this the motor will not have spark when attempting to restart (again, the switch still tests fine during this when I unplug the connector and check with my meter)
This makes me question how the ignition unit works. Is it designed such that if you press the kill switch it will completely kill the motor and only allow spark once it knows the motor is completely shut off and you are trying to restart? If so, I am thinking that my ignition unit may be on its way out and will not allow spark because it still thinks the motor is still spinning from the last time the switch was pressed.
