Vts only works one direction

[jwall116]

When I purchased the ski the vts did nothing but click
I checked the 15 amp fuse and was good so I purchased an entire vts module used on eBay. Pulled old one and got same reaction from the used one

On a hunch I pulled all fuses and realized that the previous owner had put the 15 on the bottom and a 5 where the 15 should go. Now I have power and the trim works going up only. Nothing on down button push.

Pulled the switch apart and ran a jumper across the connectors. Works in up but not down. So I can deem the down button is not at fault. I pulled the connector right before vts and tested for voltage either direction. Nada. Is this a resistance switch ?

Good news is I now have a vts for sale ! Or a backup.

When you say you got a complete system. Do you mean both the module and the motor?

 

[mikidymac]

I have had them do the same thing and it has been the module. Replacing them with a tested good entire unit has always fixed the problem. I buy mine from minnetonka4me and he guarantees them.

 

[Coastiejoe]

Almost always a module.

 

[flavboy]

you know these motors are just car window motors yeah?

 

[jwall116]

I purchased a complete VTS module that was used. Now both my old unit and the new do the same thing.

Old unit -- Will not stop going up but nothing down

New/Used unit -- Stops going up but nothing down.

What tells the unit what position it is in?

Any testing I can do for the switch?

To rule out the motor just apply 12vdc to the 2 motor leads. Doesn't matter what is + or - then to test the opposite direction switch the + and -.

 

[jwall116]

I will conduct this test when I get off of work.

Just odd that both units have the same issues.

With the motor removed from one unit, I moved the slider up and down and looked for a trim indication change, didn't notice it. Not sure what the refresh rate is on that gauge.

 

[jwall116]

Okay so tested using ohms at the connector just before vts. Up gave me a reading when Button pushed. Down was no change. Vts is good, now to track down the other issue. The button it self sounds different than the up and start. Makes a much louder click. Will continue testing after xmas. Girl might kill me if I work in garage on xmas !

To keep the vts I have as a spare or resale. Hmmmm

 

[jwall116]

Fixed it.

The down lead going into the mpem was pulled out and not making contact.

It over throws going down and always reads up trim. This I guess I can live with but it's works both directions now. Vts fully installed with a new boot

Thanks for the support

 

[Coastiejoe]

Very good. I use my VTS all the time.

 

[jwall116]

Few questions

The digital indication of trim position does not work. It displays the same no matter the position. Is this a faulty magnet possibility?

Up trim stops just fine but down will over throw and go beyond the worm screw. Meaning it disengages and I had to remove the motor to realign it. Now it's an issue. Anyway to fix this ?

Biggest question.
Does anyone else's vts move at all when you push on it ? It has a rubber mount inside ski and the bolt in back. Seems it should be able to move a little. Don't want to get to the water and find out it leaks at the bolt.

 

[mikidymac]

The trim unit should not move when in operation.

If it is overthrowing in one direction then the VTS brain box is bad. If it was going past it's limits in both directions it could be the magnet. Honestly just get a tested good one from Minnetonka4me and be done with it.

I bought this one used on eBay

There needs to be a plastic spacer on the vts housing that's what keeps it from moving around. THe magnet also needs to be strong enough for the housing to read it. If it was me I would buy both for nick Minnetonka4me because he sells quality WORKING parts. Then trouble shoot the unit it still might just be a bad magnet.

[jwall116]

And I bet there is no way to see that spacer without pulling the entire unit out. I don't recall it but it does move slightly when pushed against

It would move around a decent amount because the whole housing would just be held still by silicone with out the spacer installed.

 

[jwall116]

The housing moves maybe 1/8". When it over throws it moves the unit by force. I have the original unit as well which is working (my issue turned out the be a bad pin into mpem)

I have some testing to do. Fun part will be removing the new style clamps on the boot.

I don't know how your removing the unit. I disconnect the linkage, remove the boot and remove the motor and shaft from inside the hull and then use a 33 mm 6 point deep well axle socket. Only about 5 to 10 mins and it's out. There are other ways like the pvc pipe trick or removing the pump.

 

[Jasonv]

Only about 12 bucks

 

[jwall116]

What's the size again for the socket. 1 1/4?

I used vice grips before but difficult part is removing the new style clamps without damaging them. The plastic style clamps on the boot. I may just use worm clamps and put electrical tape as an extra layer between the metal and rubber.

 

[mikidymac]

The new clamps are easy to remove. Just a little pressure between the teeth with a small screwdriver and they pop open.

 

[jwall116]

So I removed the old unit and bench tested the old and "used" one.

The magnet is bad in both. One works better then the other and using that one I could slide it into both units and get a reading. Not accurate ones but indications moving along the scale.

What's best way to replace magnet ? I now have a spare vts to keep or sell.

Pm [MENTION=41828]Minnetonka4me[/MENTION] and just buy another one. I'll bet he has a shelf full of them
