VTS trim moves only in one direction

I pulled the motor and it works fine in both directions. I also can turn the worm screw in both directions with no problem. Its not binding and it moves pretty freely in both directions. So when I turn the ski on and power up the engine why does the trim only move one direction. I push the VTS button and it moves the jet nozzle down, but it will not move up. Whats up with that??? Could it be a bad button/switch or is their something wrong with the VTS trim housing module? Can I just replace the button assembly or do I need to replace the housing module?

Thanks guys!!
 
either, the switch is bad, the wiring is bad, or the controller has given out.

Check the switch, and wiring connections first... but the controller is fragile, and are known to burn out.
 
switch

can u put a tester on the switch (ohm) or jump it and see if it works then?

my best guess is the sensor that tells the system the trim is fully up/down is broken... so it think's it's fully X, and thus won't budge...

unlike power windows where u can hold the button forever, these shut off the motor at the end of the motion...
 
Was going to do a new thread for this bit will try here first. I need help. Went for a ride today. All was good. After a few blasts at 113kph - 70mph the ski Seadoo rxp 215 2008 was going great. I had adjusted trim a few times. All good. Then my buzzer sounded for about 5 seconds as it does if fuel is low. Fuel good very close to full tank. Th next time I pressed the trim down the buzzer sounded again! The trim indicator in dash moved up when I pushed trim up with no buzzer, but no change to trim line in dash when I pushed down. Every time down pressed jazzed alarm sounded. As I was on my own I could not check when I got ski on trailer if there was any movement. Any advice please.

Sounds like the module to me. My brothers did the same thing, went down but not up. I got thetrimfix, and in the instructions talks about shaving the worm screw, did that and with the motor out tested it on the battery it worked. Put everything back together after shaving the worm screw and it worked again. Never had to install thetrimfix. But for his ski I think it was just stuck.
I'm guessing you checked the fuses? From my research I haven't read much about the switches going compared to the modules. Guess they just suck!
 
i have a link, i did some research on this...cuz mine doesnt work at all..never did..
supposedly, there are glass sensors/modules in there that are delicate/go bad...which control up n down...i think thats what i remember..heres the link...ill post it in the other thread too...
C:\Documents and Settings\Eco Discovery.DJYFSCD1\Desktop\Variable Trim System Analysis.mht
 
looking at the link i posted, and its path is thru my desktop cuz it was saved, so it might not work...
but if you google: Variable Trim Analysis
then you should get there...

YUP they break or whatever. I read smacking it with a wrench can fix it too lol. I did that to my bros when I first started playing with it and it made it work, but then got stuck all the way down yet again.
 
the guy i bought my ski from told me it "worked"
never thought to test it, first ski,
and when i tried it, it didnt work...
dont know if its the buttons, (i replaced the start button, but not the vts ones when i had it opened)
or the motor...the motor and everything LOOKS clean, but it has been flooded a few times...
i have a spare vts motor, and i hooked it up to negative and positive on a 12v battery and got nothing...
if it worked, it shouldve done SOMETHING when connected to a battery right?
thank god mine is at least stuck it the straight position...

That sucks, why I water tested mine and my bros when I bought them, tested everything out. But you know how it goes, soon as you get it home that is when things start to go wrong.

Yes... as soon as you connect it to a battery it should start spinning. Connect the opposite way and it will spin the other way. It's easy to fix if it is stuck down to manually put to center.
 
yea, well thats good to know, as i put it on both polarities, and got nothing...
i might take the one out in mine and just test the motor to see if it works...
trying to rebuild my spare mpem first...(was the original that i blew while jumpin it from a car, dumba$$) thank god a had the extra one..
also, how do you manually move it? when i was checking for a leak, i checked the vts assembly coming out the back of the ski, and even disassembled it...it wouldnt move up or down..
reason i ask, is because if its permanently stuck in the middle, should i make it permanently stuck in the down or more downward position to gain a little speed?
 
Well by the sounds of it, that motor is done. I would test the one in the ski tho. Really easy to get out, as long as it isn't corroded onto the bolts. My brothers was, the very bottom bolt, over 2 hours later of Fin around finally broke free. A little hole piece broke on the motor, but got it off and went back on np as that piece didn't affect anything. If you don't have any of that, to take the motor out 5 min, 4 nuts and pull.

Manually move the trim, 2 ways really, the trim rod at the back of your ski. Loosen the lock bolt (on mine anyways) then twist the rod in or out will adjust it some what, but the best way without messing around with that rod as it is set, when you pull out the motor and loosen the rod to that connects to the nozzle, you can then turn the worm screw by hand, or you can take the worm screw right out and turn it by hand and put it back in since you already have the motor out. I would just pull the motor twist the worm screw from the back of the ski and put the motor back in. For me I wouldn't run it all the way down, at least half way up or just above.

I read about your mpem issue in another thread, ya that really sucks! Hope you get it fixed!
 
well my MPEM is fixed, im using the spare one i had...im looking to fix the original one that came out, which was blowing the 5amp fuse...
as far as the VTS, if im not going to gain any performance, im not gonna mess with it...
so from being straight out, would i gain any speed by moving it a little up, or a little down?

Personally I love having my VTS, I use it all the time. But you were talking about just setting it until you fix it? Down you will lose speed, up you will gain. I'm gonna play with mine a bit more next year so I can raise it a bit more then now and get the nose out of the water more. The less the ski is in the water that faster it will go. BUT to much and you start that bouncing BS, why I like the vts, trim down a little no more bouncing, trim it up when it stops. OH then there is jumping, trim it right up for that... good times lol.

OK Since my above post, my problem has been fixed. All it was, was a broken wire. I dont know how it was broken but when fixed it all works again. Problem is the 10 minute fix at the jetski shop cost me $150.00 I think thats a bit excesive.
 
glad to hear u fixed it..sucks that it cost u $15 per minute to fix tho.:banghead: gonna try n get to mine in a few days
 
That's messed up! Why we are on these kind of forums, cause dealers are just stupid on what they charge now a days. Did you even try looking? Least it is fixed! Sucks about the cost.
 
bill, if u just remove the vts motor, and keep the housing, can i just adjust it like that, or is it less time consuming and easier putting on a manual adjust from an spi?
 
Yea, some guys have done that. I've used the manual and like the #-4 setting. five degrees down. Whatever you like you can adjust it.
I am passing up a spx with similiar. Wife wants new car.
 
The motor has to stay in there...otherwise the VTS rod will not stay secure.

If you really dont want to fix a VTS housing you can run the two motor wires out of the housing and just touch them to the battery and adjust it till you find a sweet spot.

I have many VTS housings and motors in stock if anyone is looking.
 
ok so minnetonka,
assuming the vts motor still works, but theres something wrong with the board/whatever sensors are in there, i should be able to take the two wires from the vts motor, run an extra length of wire directly to the battery, and that will move the trim? and if i just switch polarities, that will move it in the opposite direction, correct?

Yes correct!

See what minnetonka is selling his for, worth it having vts IMO. I didn't know minnetonka sold them. It's very easy, either way. Pull off the cover and you will see for yourself. It could just be stuck like my bros ways.
 
okie doke...off topic, but i dont wanna start another thread for this one...
may be checking out a 95 900 zxi (kawi)...and dude says "perfect compression" at about 80 psi....
I know kawi's are lower compression (from what i've read)...but that screams rebuild to me, no? anyone know what a 95 900 comp should be?
