VTS bad???

[codybrown]

Does the vts system ever go bad on '96 xp's? I was told that I needed a new controller. Well, I pulled the electrical box out and replaced a blown fuse. Now I hit the vts button, and it sounds like the motor clicks. I know the motor works because I tested it with a battery charger. Does the ski have to be running to power up the vts?

Re: VTS bad???

I have a VTS question as well. I have a seadoo 97xp and a 99xpl. The trim doesn't work on either of them. They both shoot the vts fuse when you plug in the 2 prong connector that goes to the vts motor. I looked at a diagram today of the vts system and don't see where the motor has any electrical connections except at the 2 wires in that plug. I have been told that the electronics are bad in both vts housings and they should be replaced. What does the flat 4 pronged looking harness that comes out of the box control? If the internal electronics are bad why does my vts guage work? It seems to me the motor must be bad, since plugging it in causes the fuse to blow, but I am being told my motor is fine but the housings are bad. If that's the case shouldn't the motor still adjust the trim? I guess not if the fuse is shot, but what if I unplug that 4 prong wiring harness? Can I try plugging in the motor then? Shouldn't it work? I am just a bit confused and skeptical. Thanks.

Re: VTS bad???

You both need new trim modules.

The two prong connector is the power source for the module, not the motor directly. The motor gets power from the module after you depress a button on the handlebars. The 4 ( six prongs on newer models) prong connector is for the buttons and the guage.

The guage can be good when the module is bad, because it is not part of the VTS module, or the VTS motor. Only a sensor in the module sends the signal to the guage to show the position of the VTS.

When replacing a VTS module, test the motor while you have it out to be sure it is good.
Replace the rubber boot with a new boot on the control rod and use plastic clamps or wire ties as steel clamps will cut the rubber over time, allowing water to ruin the VTS again.

Three tips to keeping those VTS units alive.
Pack marine grease into the rubber boot to keep water out of it.
Smear a thick layer of silicone over the potting material on the top of the VTS module to cover it so it will not dry out and crack, which if it cracks, it lets water into the circuit board and poof! You need a module.
Use vasoline on the rubber seal for the VTS cover and be sure the rubber gasket is propely installed and not twisted.

Well, that makes a lot of sense. Whenever I opened up the plastic housing for the vts motor, it has a lot of water in it:emoticonc So from what you said, I take it the vts module is behind the motor then? Where's the best place to purchase the new module?

Re: VTS bad???

Thanks, I pulled my cover off and disconnected my motor, then ran a jumper from the battery and was able to operate the motor, so my module is definately the problem. I trust my mechanic, it juust never hurts to get a second opinion.

Re: VTS bad???

The ONLY place you can purchase a new module is from Sea Doo parts or from someone who bought one from Sea Doo parts.
