Nitro's waste gate solenoid super quick check procedure

[dav_dman]

Quoting Nitro..so i dont have to post a link to pwctoday ;-]

"Here my simple check.

With the WGS installed and the ski NOT running. you should not be able to blow through it. (use either hose)

When the ski is running at idle, you should be able to blow through it.

Do you have a pic with wgs location??? can you post it thank you.

[dav_dman]

get a service manual and i'll help you find the section that shows it. You really shouldnt do anything to your ski without one.

the wgs is on the back of the engine, just behind the intercooler pipe.

nice wave jumping vid in the other section, btw..

THANKS, i just got my book the other day, it's a plus to have one.

It is almost warm enough for me to go skiing again so I was servicing (oil, filter etc) my ski today and whilst it was running I checked the actuator push rod connected to the wastegate

It didnt feel like it was moving so I watched it and never saw it moving at all whilst the ski is running. With the ski stopped I gently moved the mechanism with some Vise Grips and whilst quite stiff it did move.

Should this mechanism be quite stiff? I do lubricate it after every use and it does not look corroded.

I then did the "Nitro quick check method" and found that I could not blow through either hose whether the ski is running or not, I also found that one of the hoses goes to a "T" piece (and from there to the actuator rod), the other hose is shorter and goes nowhere.

Does this sound correct(I assume this hose draws/releases air into the hull)

Does the ski need to be in the water, ie under load for this to function correctly? The ski has been in storage since the end of last season and ran fine last time out (59mph GPS)

Thanks in advance.

The actuator is very stiff the spring does not begin to open until about 8PSI. It is much easier to check with compressed air as long as you don't overpressurize it. If you could move it, it is not seized up.
If you could not blow through the WGS while running at Idle, it is bad. If it's under warranty, have them replace it, if not you can carefully open the twist-tabs on it and free it up with some CRC 656 like I did. Sometimes they are beyond repair if they are corroded severely or the tabs have been twisted before.

Thanks for the help JR

Yeah I reckon the actuator aint seized, as you say it is very stiff but can be moved

I also agree that I have a dodgy WGS (as I cannot blow through it) but was not aware that it could be opened/repaired, I will try that tomorrow

So, to clarify, If the repair is sucessful I should be able to blow through the hose on idle? Or does the ski have to be at specific RPMs before this is possible?

The shorter hose from the WGS does not go anywhere and simply releases pressure into the hull if/when the solenoid allows it to, Is this correct?

I may order a replacement also, and have found this:

Is this the correct item?

Thanks again for the assistance

[NitroShark]

That is the correct part number.

The procedure is as posted above.

With the WGS installed and the ski NOT running. you should not be able to blow through it. (use either hose)

Yeah definately sounds like I have a dodgy solenoid

I will order a replacement and investigate further tomorrow

I assume this is a simple 12V DC item and so could be powered by a battery for testing purposes if removed from the ski?

[JRINJAX]

The output to the WGS is a Pulse Width Modulation signal of unkown voltage but it won't be near as high as 12VDC. I would guess it is probably about 4VDC PWM since it is being handled by the micros in the ECM.
Carefully untwist the locking tabs and open/clean it with CRC 656 if it's not in warranty. You don't have anything to lose and $70+ to gain.

Fair point.

If I cannot easily exactly replicate the voltage needed to operate the solenoid then I will test it on the ski

Hopefully get a crack at it this evening

I still reckon it would be prudent to acquire another as a spare.
