I've been having trouble with the VTS system in my 97 GSX, and since I couldn't find any VTS discussions here, I went searching elsewhere and found this very good article on the VTS system in our seadoo pwc's.
It has a very good troubleshooting section which has many more tests to do on the VTS module box than the one test the manual shows. This guy actually somehow removed the black stuff that seals the circuit board in and analyzed several bad VTS module circuit boards that were donated to him for that purpose.
It might save someone some money from throwing parts at a problem to fix it.
