99 gsx limited stator running/charging issue

[Rabid]

I didn't think to test the stator on the trailer. I fired up the ski after sitting for a week with the battery disconnected. I had run the ski hard two weeks ago with no problems. It turned over a couple of times And quit. I charged the battery and it took a good while to charge up to 13volts. I had a new battery on hand and the ski cranked right up and I did a run on the channel with no problems. I came back to the dock and checked the voltage at the battery at 1500 rpm and got 13.4v. I did some reading up on stators and rectifiers. I had my wife run the ski up to 3000 rpm and got a reading of 14.2v. I checked the continuity on the yellow wires at the mpem and had the wire closest to the front did not show cont,the second wire did show cont with the third wire. When touching the third wire I did not get a clean sound but registered a value.

What I seem to have is a ski that has enough voltage to charge the battery, but the stator can not power the ski hence the dead battery.

Does this sound like I have a stator problem or is there an issue with the internal rectifier also?

13.4v > battery stationary voltage. 14.2v is definately charging. So I don't think you have a problem with your stator/voltage regulator.

I don't quite understand what you are getting at. If the battery is charging...why is it dead? maybe you have a dead battery? why do you think it's your stator?

Edit:
You should be looking for the yellow wires resistance to each other and also each wires resistance to the engine.
Each yellow wire should be very low resistance to each other and completely open to the engine.

I was thinking that the stator was malfunctioning and the ski was running off the battery. I did leave the neg cable hooked up and disconnected the positive. It could be that this battery can't hold a charge when sitting and not on the battery minder.

Here is a pic of the battery after I charged it and it sat for a couple of hours. The 13.05 today was charged and rested. The 13.04 was the voltage when I pulled the battery out after trying to start the ski. I had it on the charger for a short time till it signalled that the battery was charged...the solenoid was buzzing at 13.04v

This is how I was checking the stator

If you connect across any of the yellow wires to another yellow wire, you should have continuity. If you check from any of the yellow wires to ground, it should read open. Sounds like one of the stator windings is open.

The manual states to test resistance between yellow and continuity between yellows and ground.

I'm going to go out and test it now

Put a disconnect on the negative side of the battery when not in use. For some reason there is a draw thru the mpem that kills the battery in a couple days. I put 1 in mine and it works great. Also adds a theft protection to your ski

Load test the battery. Your battery should last at least a few months while connected. No need for a dissconnect.

I find mine discharges within 2 weeks while connected. I just leave an intelligent 2 amp battery maintainer on them now when not in use.

None of my customers have that problem. If they did, I would fix it.

I purchased a 1996 GTX. It has a really nice battery disconnect. I asked why they had it on there and the owner said the previous owner had electrical issues. As recorded in another thread I found the middle yellow wire on my Stator OPEN.

 

[Triorieel]

Open won't hurt anything, it just means it's not going to be as strong at charging as it should be. As long as it can give more juice then the seadoo takes to run, you are fine.

 

[Rabid]

Do you guys have a "test connector" when you check the stator that is mounted in the ski..I can't get in to check at the mag cover. if you check at the mpem you will include the resistance of the wire correct?

 

[Triorieel]

Some people have made a connector for testing.

But the resistance of the wire should virtually be zero unless the wire is frayed or destroyed.

If you get readings within expectations, you are probably fine.

If you get an open connection, you can test the wire itself for continuity from the mpem to the connector.

If you get a resistance value way off, again you can test the wire itself to eliminate it as a possibility.

I did a run down to pine island which is on the southern end of Lake Livingston and the ski ran fine. This is the first major long run that i have done. I checked the voltage on the battery when I got back and it was reading 13.4v.

I guess it was that older battery having a weak charge.

Thanks for the help!!

You know I'm not afraid to ask a dumb question...lol

Resting voltage good.....load test bad
