Speaking of which, if your VTS motor is corroded or extremely weak or gets hot. The pro's are that you have a more reliable VTS that will probably work for a long time, the neg's are that you will lose the VTS gauge function, and possibly wear out the VTS motor faster depending on it's condition. Where as in this case, the motor will normally see over-current situations every time it hits the stops. The reed switches of the original VTS module allowed the motor to be cut off using switches and therefore the motor never saw any over-current situations. Same as the way the VTS motor will work when you use the "VTS fix" module. Understand? You can still navigate yourself, but without eyes your just going to keep bumping into things before you realize you need to move in a different direction and ending up with bumps and bruises in the process. If your eyes are open, there's your feedback loop, and you can navigate without hitting walls. Your going to find walls, but not before you bump into them to let you know they are there. It's like walking around in an unfamiliar room with your eyes closed. His unit is "crude" in the sense that it does not have some sort of feedback loop like the original design of the VTS module. One more item, because I don't remember seeing it on his website, your trim gauge will no longer be functional. You could just call the circuit breaker I'm talking about a "automatic resetting fuse." It performs the same function as a fuse, but now you don't have to keep replacing fuses once they blow. Once the circuit breaker cools down(because to much current heats up the bi-metallic element which breaks the circuit), it resets itself. If something were to get jammed in either one while in operation, the circuit breaker would cut out the power once the amperage load of the motor increases beyond a specific threshold. This same type of breaker was used on older GM vehicles with power seats and power windows. This is why your starter motor on your car (or on your ski for that matter) requires more amps to get the engine turning from a cold start versus what the amperage meter says when it's tested on the load bench at the parts store. But if it's trying to move past it's stop and can't, the motor draws many more amps. To overcome the resistance of water pressure, the electric motor may only use. I'm guessing he's using just a couple of automotive style circuit breakers with a low amperage rating, say 3 or 5 amps. Thus, the motor isn't trying to forcibly move the trim any further than it's originally designed range of motion. The "VTS fix" senses this and cuts the current. It works like this: whenever your trim motor reaches it's newly created mechanical stops, the motor will immediately try to draw more current. Hopefully the designer engineered a few more redundant circuits inside in to keep from burning anything up.

The electrical portion of VTS fix is no more than an over-current cutoff switch.

If the piece that rides on the threads is kept "captive" on the threads, then you have effectively limited the travel of the VTS mechanically and not electrically as was the case with the stock setup. My theory behind why the trim fix works is how he manages to keep the plastic piece on the worm screw from running off the threads. In any case, he sends along with his magic box a collar which is just a piece of PVC to keep the trim from overextending. He's even encapsulated the electronics like Bombardier did with the original VTS box, though I'm sure the stuff he's using is a bit better. First of all, the construction seems to be first rate. I've just bought two of them and have examined them closely. Does this "fix" unit allow your VTS to stop at each extreme or is it supposed to sort of bind at each end? Does this guy who makes this have a phone number? I didnt see one on his site. Im thinking it would need power to get this to happen.

The origonal VTS circuit board uses a series of "reed" type contacts which are triggered by the magnet to send the position of the nozzle (actually its the plastic screw slider with the magnet) to the gauge.
