1997 GTS bogging issue - Need help

[rkkoeb]

I did the fuel pressure test and used soap and water around the fittings on the fuel sending unit and didn't see any bubbles. I think I am going to try to replace the rectifier and see what happens. Going to see if the local dealer has one in stock. We are having mid 80's this week so I am missing out on ridding.

Like 30 bucks on eBay but the oil system pressure test is a part of the sky running correct .if it is leaking it will not run right carbs run off the sealed engine .but the rectifier is a good thing to replace so any ways keep us posted

You said you used soap did the system hold true pressure for the 10 minutes.and did you feel the pressure come out of the safety valve when you release the line clamp

 

[rkkoeb]

yes air came out of the safety valve when I removed the clamp. Not sure how long I did the test for

Can anyone tell me the location of the rectifier? Is it in the white box?

 

[omboli]

It's on the main electrical box

In the main box

Updates: First I did order a new rectifier and it should arrive tomorrow. I just did a test with a meter on my current one. When I start the jet ski I show about 12.5 volts with the engine running at the battery. As the engine is running the volts start climbing up into the high 13's. Not sure if that is correct or not.

Second I found a water leak in the exhaust manifold just above the battery area. It is a pin hole in one of the round caps welded into the side of the exhaust manifold. Not sure if water getting down by the batter causes issues or not but I will repair that toniht.

What is the thoughts of the current rectifier? Is this correct?

The rectifier appears good. Anything over 15 VDC is no good. Did you gradually rev the ski to 5.5krpms under this test?

That welsh plug will need to be welded up. You'll need to remove the pipe and have all 4 plugs cut out and grinder flat and welded up. No sense to do just one.

Hi my 01 had same problem, found no O ring in strainer and replaced selector runs like a champ now

Here is the Charging Test:

Can the rectifier get hot and then start having issues? Reason I am asking is when you first take it out it runs great with not issues, after about 10-15 is when the issues start. If It was a fuel issue I would think it would happen right away and not just after it warms up. I didn't see how high the voltage went do to the water leak spraying on the battery area. Once I say the water leak I turned off the jet ski.

 

[omboli]

Sounds thesable when mine went bad it would run good for about 10 to 15 minutes then start having issues

 

[Cliff787]

If an electronic component such as a rectifier is getting hot. That isn't a good sign. An internal failure will happen or start to happen as the internal material breaks down eventually causing an open circuit.

But since you couldn't fully complete the voltage & current test. I would suggest to repair the water leak first and then retest the rectifier.

 

[rkkoeb]

I already have a new rectifier coming tomorrow so I am just going to install it right away and take it on a test run again.

 

[Cliff787]

Good deal !

You can use some of the 2-part epoxy putty to plug that pipe hole to get you by in a pinch. Better than pissing water all inside the hull.

Update: JB weld took care of the leak. New rectifier came today and I installed it. Took it out and it runs GREAT! Ran about half of tank through and no issues at all. I want to thank everyone who helped me out. I would of never been able to figure this out by myself. Thanks Tons!!!!!
