2002 Seadoo GTX-DI Maint Problem

[steve.smith@esker.com]

Hi everyone. I have a 2002 Seadoo GTX-DI which has been a great machine until this year. The first problem is it suddenly is draining the battery. I took it to two authorized Seadoo dealers, the first put in a new battery (which didn’t work), and the second suggested disconnecting the battery after every use (they could not find the source of the drain, but did detect it). That works, but is a pain. My latest issue is I’m getting a Maint warning every time I accelerate, and it goes into limp mode (max speed around 35 MPH). When I idle, the maint light goes off. I accelerate again, and within a few seconds the maint light is back, and I drop to limp mode. This only happens with the Yellow or fast key, the white one works fine. Any ideas for either issue? So far I have been unimpressed with the BOMs system, because it does not seem to tell the dealer too much. Any help would be greatly appreciated. Thanks

I keep trying to reply, but it never shows up. Thanks to everyone for your input. I can see how the rectifier will help my battery draining issue, but will it fix my issue with the maintenance light coming on when I accelerate? Again, when I accelerate, it comes on and drops to limp mode (about 35MPH). When I go back to idle, it turns off. Pushing in the Mode/Set keys does not clear it. Do you thin the recitifier will fix this?

First of all there is two things you need to remember on your DI. One it has to and I mean it is a must! that you have a good charging system. I have discussed this in a few other posts on DI's but you need to check it. Without a good charging system your Sea-Doo will not run right. Best thing to do is to take a voltage meter and put it on the battery. Next start the sea-doo and rev it up. I mean close to 5500 to 6000 RPM's. If the voltage drops you need a rectifier. If the rectifier does not fix it it may be in the stator. Number two, if the dealer did not reset the maint light i believe that you can reset it on your own by holding the set and mode button. The maint light may be on due to a charging issue.

Thanks for your reply. I did press the mode/set buttons each time, but it did not reset the maint light. I actually changed the battery too (freshly charged), but it still would not go away, so I'm not sure if the maint light is connected to my drain problem or not, or a whole new problem. Like I said, it only comes on when I accelerate. It goes off when I idle. I believe the dealer did put a voltage meter on, but did not think it was the rectifier or stator, but I'll check again.

I took this to two separate authorized dealers, and was told they put a voltage meter on it. They said they could not determine exactly what was draining the battery, which is why it was suggested pulling the negative connector off each time. Again, that seems to work because the battery is charged. I did press both the mode & set buttons, but that would not reset the maint light. It only comes on when I accelerate, and then goes back off when I idle. It did not come on with the option “slow” key. At this time I’ll probably take it back to the dealer, but this will be my 3rd visit.

I have replaced 2 rectifiers in mine I would bet money that that is your problem........ unfortionately most dealers dont know how to work on the DI models.........my new rectifier i got from sea doo source .com and he uses a more powerful rectifier. it has worked beautifly.

 

[justy_123]

I have the exact issue with my 2004 XPdi. I bought a new rectifier a month ago and going to test it out 2mor! I so hope it fixes the problem!

There are so many posts on this forum regarding rectifiers and DI jetskis! Its unbelievable! Certainly a design flaw. I am very thankful for having access to this forum!

 

[steve.smith@esker.com]

Thanks everyone for your suggestions. I think I'll give the rectifier a chance. At this point it may be better than taking it back to the dealer for the 3rd time!

 

[steve.smith@esker.com]

I guess I do have another question. I can see how the rectifier can fix my battery issue. I do not understand how it can fix the maintenance issue I am having though. I put in a brand new battery, and the maintenance light still came on when accelerating, but would go off when I was in idle. To me, that seems unrelated to the other issue. Would you agree?

 

[jhdarby]

AMEN to that Justy !!!!!!!!!!!!!!!

 

[rxtxfreak88]

The 947 DI was a terrible motor all the way around. I am a dealer and when a DI comes in and they say it is not running right the rectifier is the first thing we check.

 

[steve.smith@esker.com]

So you feel the Rectifier would fix the problem with the maintenance light coming on when I accelerate? Again, it goes back off when I go back to idle, and then will come back on immediately when I hit the gas again.

 

[steve.smith@esker.com]

I'm all for replacing the rectifier and can see why this would fix my battery draining issue. However, will this really help with my maintenance light going on when I accelerate? Again, it goes back off when I drop it to idle, and then back on again as I accelerate. I drop to limp mode and the machine will only go about 35MPH. Will a rectifier fix that?

I am double posting here, forgive me... but I want to be able to monitor this thread via email notifications also...

So how do you replace the rectifier? I'm not even sure where it is...

 

[deepdiver]

It is usually in the electrical box with the EM, ignition coil, and starter solenoid. Should be easy replacement. Look at electrical diagram in your service manual.
You should check the rectifier first. Put a voltmeter across battery and run your engine up to about 5500 rpm. Voltage should be above 13v to charge battery, usually about 13.5-14.5. If under 13 v or over 15 v the rectifier is bad.. again see your manual.
Another possibility is a bad charging coil but this is less probable.

It is actually just aft of the computer on the port side. Not to hard to reach with 10 mm sockets mayby a swivel

rectifier or stator

I have replaced 2 rectifiers in mine I would bet money that that is your problem........ unfortionately most dealers dont know how to work on the DI models.........my new rectifier i got from sea doo source .com and he uses a more powerful rectifier. it has worked beautifly.

Thanks for your response jh. I found it shortly after that post by finding the part number out and then looking at online microfiche.

So here's my scenario: the maintenance light goes of and the RPMs are retarded to about 4750RPM with in seconds of starting up and taking off. This happens 98% of the time, the remaining 2% of the time, it takes maybe a minute and a half of running for the condition described to occur. When it does occur, the warning is: MAINT ... 12v LOW.

So I unplugged the rectifier, no change, still occurring. Do you think it is the stator or the rectifier.

Thanks in advance.

 

[rxtxfreak88]

Unplugging the rectifier is not going to help make the light go off only make it worse. You need to try a new rectifier. That is 9 times out of 10 the problem.

Mines fixed

Rode my 2004 XPdi for the last 2 days non stop and my exact problem, what you have got, is fixed. Very happy! :hurray:

So, I would definitely replace your rectifier like I did. I just bought an aftermarket one for around 100 bucks.

This is the first rectifier i have replaced on my ski, however, I have only had it for a year!

Goodluck

Thanks justy, looks like that's what I'll be doing.. why'd you go aftermarket?
Did you get it from America, or down under? What brand is it?

 

[justy_123]

I bought it from E Bay. From Australia I think. The genuine ones from my dealer are double the price so I went with an aftermarket one. Time will tell how good it is.


Good luck. I bet it will fix your problem
