Electrical Issue? Need Help!

So let me start by saying I am new to the Sea Doo world and I am at a loss at the moment with the situation I am experiencing.

I purchased a 2001 GS 717/720 from a dealer after talking with the mechanic who took it on trade. He said that it was running fine when they took it but after winter there was an electrical issue and all that it needed was a new MPEM because traced power stopped at the box. I replaced the MPEM and was able to detect power (when i hooked up the battery it gave me a small chirp). However, when I hooked up the lanyard to the DESS post it began to beep continuously until i pressed the start button and then everything went silent. I took the lanyard off and back on to no avail (no beeps, no lights at guages, nothing). I disconnected the battery and reconnected to experience the same exact situation with the continuous beep once i connected the lanyard. The self diagnostic of pressing the start button 5 times does nothing. I thought it would be a bad DESS post. Replaced that, same situation.:facepalm: I went through and gave all the grounds and connectors a quick review and everything appears in good condition. I would like to note that with the battery connected, every time i disconnected a clip or detached and reattached a ground, i received a small chirp (not a beep) from the steering column. I am assuming this is letting me know there is sufficient power at these locations. All fuses are in good shape, front and back..

So i went to the solenoid. I jumped the solenoid with a screwdriver and began to hear a click/spinning sound coming from the Stator in front of the engine and the continuous beeping started up again (with lanyard connected). There was no cranking of the motor. I am waiting for a new solenoid in the mail but tend to think i have another issue at hand. Would a bad solenoid cause me to not get the desired two beeps and start?

I searched through multiple forums but have failed to find a situation like mine. Any ideas are greatly appreciated!!!!:thumbsup:

Pull the plugs and turn the engine over by hand. If it cranks, then jump the solenoid. Does it crank or not.

Post your results and we will go from there.
 
I will try that when i get home but i already jumped the solenoid and it didnt even try to turn over, just started beeping continuously until i disconnected the lanyard and i could also hear a spinning/hissing noise coming from the Stator in front of the engine.

But the plugs were in when you tried, yes?
 
I would be calling the mechanic. Are you sure he used an OEM MPEM? The aftermarket ones are junk.

You should not be getting any beeping when you connect the battery and you should not get any noise from the stator when jumping the solenoid. It sounds like something might be crossed in the electrical box too.

I replaced the MPEM with an aftermarket:leaving: from a jet ski supply site that says no programming is necessary. The beeping i am getting when i first connect the battery or R/R grounds and connectors is a very short chirp much like that of a smoke detector when the battery is getting low. It is not your typical beep you should get when connecting the lanyard.
 
Well they are wrong. Your ski has DESS so your key has to be programmed to it. Like I said the aftermarket ones are known to be junk out of the box. It should not be beeping when you connect the battery.

Hmm, that's not what i was hoping to hear. Here is the exact quote for the website i bought the MPEM from. Not saying you are wrong, just trying to view this from all angles before i end up returning the MPEM and having the same issue. I appreciate all of the quick feedback so far!

Arieltek aftermarket MPEM CDI

"this MPEM does not require programming a dess key to it. It only uses the dess key for contact on the dess post to energize the starting circuit, so any dess key will start the PWC"
 
So basically it is saying that your DESS key no longer secures your ski, any key will work. I still say it is a bad aftermarket MPEM considering it doesn't even function like a stock one.

If the MPEM is bad, would i still have a response from the lanyard the first time it is connected after i reinstall the battery? It only happens the first time and then nothing. Its like i am receiving a reset response. I can repeat the action every time i R&R the battery.
 
I recommend doing as I suggested and we NEED to start with a known good or bad. Guessing will cost you a lot of aggravation, grief, and money.

So I just got done pulling the plugs. The motor turns over very freely by hand. Nothing is locked up. When I go to jump the solenoid with the lanyard on, the ski starts beeping continuously and I hear a spinning noise coming from the front of the motor and no turning over or starter action. I got curious and checked the voltage on the battery again (I had it charged fully with about 11.5 volts) and it showed 4.8 volts.... battery is back on the charger but with voltage that low the battery is probably fried. Are the symptoms I'm experiencing solely from a low battery? Shopping for one tonight.
 
Yep. Low voltage is a MAJOR issue. It will smoke solenoids and the starter MAY spin but not engage.

Take the battery to an auto parts store and have it load tested. Guessing is a waste of your time and effort. I'm sure the battery is junk.

Thanks, the solenoid is on the way and I'll be getting a new battery since I have no idea how old this one is. I will post back this weekend with an update!
 
Great news. Replaced the battery and got the two beeps. Guages lighted up and work properly. Hit the start button and click..click. So I replaced the solenoid with the new one and now the engine turns over. I can't get it to fire yet, don't smell fuel either. I have the shut off valve in the correct position. Anyone opposed the starter fluid in the intake? I havent checked for spark yet but have never done it and d9nt want to screw anything up. This thing probably hasn't run in athe least a year.

No starter fluid with 2-strokes as there is NO OIL in it. Use some premix and put it into the carb/intake.
 
I assume you have a carbed ski. If so, a couple of teaspoons of premixed right down the carb.

Or, bypass the entire fuel system and run it from a remote can with premix in it.

Make sure your pulse line is connect AND WORKING.
 
I was having issues on a 2000 gtx di (non carb) not firing, to test if it would run, I just put some premixed fuel into each cylinder and hit the start button, and it ran till it was out if fuel so I knew I had spark and it ran, just had to figure out why it wasn't getting fuel.

Thanks for the input, did you find the culprit? I am going to play it safe for now and start by checking for spark with a tester this weekend. I have a feeling it's not getting fuel, didn't smell any while it was turning over and I pulled the line after the fuel filter and it seemed empty. Filter and lines look pretty rough so I will probably end up replacing those.
 
Yes I found the problem, but if yours is a carbed engine then my solution won't wirk for yours, mine was the air injectors.

You can check spark by removing the plugs and put them in their respective wires, ground them, hit the start button and they should spark.
 
1. Aftermarket MPEMs will bypass the security feature and any DESS key will work.

2. Just put some gas in each cylinder through the spark plug holes and see if it fires.

3. It is simpler to prime the fuel system doing this instead of excessive cranking on the starter.

Update: Both cylinders have spark so I will be replacing the filter and lines and we should be good to go. Thanks everyone for the help.
