I bought a used Seadoo XP (1996) in July this year.
The problems started with a defective coil. Coil was replaced and the VTS-Module started to smoke although the VTS-motor works in both directions.
VTS unplugged and Jetski brought to garage because the motor didn`t start anyway. The starter worked fine and the ignition-system too. But the engine spit out the fuel of the carbs when giving throttle.
The garage switched something in the rotary valve and the engine runs! But only in the idle-RPM and the highspeed-RPM range. In the midspeed-RPM range, the engine is running bad. In the next phonecall from the garage, the statement was: "I checked the carb but there are no probs but if I plug back the VTS, the engine works fine". But this should not be normal because an unplugged VTS doesn't causes engine probs.
Okay I thought, lets get the ski home and try it on myself. Till yesterday the ski was since July in this garage.
I read the wiring diagrams and I couldn't identify how the VTS should relate with the ignition system. I put the ski into the water and started it.... everytime in the idle-rpm it runs for a minute and then the engine stalls.
Giving some throttle in the midrange the engine is running bad. At higher rpm-ranges it speeded up nice till I disengage the throttle lever, then the engine sometimes stalls. I thouht it could be the RAVE but the service told me that they had tested them and they were mechanically okay. But they didn't checked the adjustement of the RAVE. I tryed to re-adjust but no probs were solved.
I worked yesterday with the ski till the bat. was low. Today I put the fresh charged bat. back and I tryed to adjust the carb. via the high-speed screews. At the end of the day the bat. was again empty although the engine was running a lot. I didn't checked the charge-regulator, but I will tomorrow (check the fuses, check the volts at the bat. while the engine is running and disconnecting the red-wire from the regulator if necessary).
So my question for today:
Does anybody knows about some corelation between the VTS-module and the ignition-system, e.g. some grounding reasons?! My wiring-diagram isn't very usefull in this case because, there is no wiring from the VTS-module and no from the control-box.
Thannxx a lot and greetings from the baltic sea/germany
Ps.: Please excuse my bad english...and commendations to some excellent threads in this forum!!
