Super Jet Wtf? Keep getting shocked...

[bondra131]

Anyone know what can cause an electrical current to be running through the motor and anything attached to it? I keep getting shocked big time if I touch the throttle wheel, the cylinder or even touch the rubber boot over a spark plug! It's rubber.. Brand new msd boots. Electricity is running all over my ski. And my ski is running like hell it hardly runs just dies if I touch the throttle. If I do ease into it and get it into higher rpm's, it doesn't run smooth.. Really jittery cuts out. What the hell? Lol. Someone have any answers? I have a bilge wired to the battery none of the wires have breaks in the insulation and I have one red cord from the ebox going to the starter, and the second red cord from ebox to the battery and the ground from battery goes to the starter as well

got a power wire for a bilge touching somewhere? all wires in the ebox connected properly? i'd probably disconnect the battery and start checking connections.

Make sure thw main ground(-) from the bat has a nice tight clean ground connmection to something on the block sounds like you have bad geound connection

I had that a few years back and it was caused by corrosion growth. I was using the JSS quick disconnect terminals and the corrosion had grown enough to contact the backplane of the ebox and light me up.

Check everything.

Make sure it is grounded properly. Had a problem like that with my 550. I was riding and kept getting zapped through the throttle. That was fun....

 

[bondra131]

Connections are fresh I just installed this motor. It did this a couple times last year but not consistent and it ran well. Now it's constant power shocks me every time and runs horribly and someone told me this is what happens when msd enhanced cdi's go bad and my msd have 3 long seasons on it...

Something grounding out on your stator? Defintely sounds like the charging circuit if it has enough potential to pop you through the plug boots.

Did you say everything in the ebox is golden or no?

Pita for my two guesses.

 

[davy87nj]

If the ground and connections are good, Rectifier possibly?

 

[swannysxr]

Sounds ignition related(high voltage) you won't feel a shock from anything 12v, low amp. Start it up, and spray the plug wires wiyh a water bottle and look for a light show

Doing it in the dark helps greatly.

 

[bondra131]

I'm not sure how the ebox looks I have not had it open for a couple years but last I had it open it was bone dry it seals really well. I'm not familiar with the rectifier... I will try out the light show thing! Lol. It's definitely not low voltage it's shocking me big time. And causing the ski to hardly run its horrible... I'm thinking my mad enhancer went bad on me

make sure the ebox is grounded to the batter and make sure the start/stop switch is grounded to the ebox.

 

[bondra131]

How does one ground to a plastic ebox? Lol... The start stop switch does clip in to the ebox... Factory set up works just fine. Oem set up is negative from battery to starter. Positive from battery to ebox. Another positive from ebox to the starter. 2 positives and one ground. That's factory. That's all I've used for years and never had a problem. This is more than a ground or connection issue something is really f'ed up

The backing plate of the ebox is made from aluminum pot metal so if you pinched a wire or have something shorted or corroded inside to ground, it could be causing the shocks. It's also a high resistance short and may not be that obvious, otherwise it should have blown a fuse. And the 12vdc potential in all of the positive circuits is more than enough to shock you, trust me. If it was on secondary side of the coil, it would be in the 15-20k volt range and much, much more noticeable.

The fact that is affects the ski running indicates that it is somewhere in your ignition system and not a bilge, battery or start/stop circuit. I would start by pulling the stator cover off and then open up the ebox. Those are the two highest candidates given the info provided. Since you recently replaced the motor, make sure you didn't pinch the stator wire under the bedplates. Although if it was doing this last year on a different motor, the ebox would be my #1 target at this point and it could be as simple as a wire squished between the cover and backing plate.

Do you ride salt or freshwater?

 

[bondra131]

Ah the back half of the ebox is aluminum huh! I forgot about that. Well I rode with this motor last year. Pulled it out for winter and power washed my hulls inside so it was nice and clean for this season. Stator cover was off that was the last thing I put on because of the pipes lord mount to it. It did shock me last year a couple times on occasion but the ski ran fine.. I haven't had the ebox apart in 2 years but in the past of opening it a few times, it was always dry as a bone. Doesn't mean it sealed perfectly the last time I screwed it together though. I ride mainly fresh water. I did take this motor in the salt water at the Blowsion surf slam last fall. It's first time in salt water. And I DID have a couple big waves crash up way higher than normal on the shore and came over my ski while changing the battery. Flooded out my carbs bad.. Took an hour of burning plugs to get it running. After that I rode for 5 minutes and never rode again until now.. Maybe my carbs are gummed up causing it to run poorly and the electrical issue is just another problem that's been existing and getting worse. Idk.. I swear I work on this thing more than I ride it haha pain in the ass jet skis. Thanks for the inputs guys! The more the better. Ill keep messin with this thing

Start with the easy. Cover the connections with dielectric grease. Do them one at a time and see if it changes anything. I was getting shocked and putting grease on my terminals solved this problem. Granted, My battery was under my X2 seat and submerged in water, and my ski had no running issues, so it is highly unlikely that you have a similar problem. However, a tube of grease is $7 and will cover all of your connections. If you clean every connection and cover with dielectric grease, including those in the ebox, you can eliminate a lot of possible causes for almost no money. It's likely something else but it would be a shame to start swaping CDIs, Coils and Stators to find out in the end you have a corroded arcing wire somewhere. You can really narrow it down to only a few things if you isolate all the connections and rule them out. Meanwhile, since it can be hard to prove a coil is bad w/o replacing it, try to find a known good stator, coil and ignition (even if it's stock) that you can borrow to test w/o spending the money.

 

[bondra131]

Ya for sure I have dielectric grease. Only ever have used it before going in the surf though. In the lake i get all sorts of water inside the hull but never have had it cause problems... I got an oem 650 cdi for Free. if all else fails, I'm going cut it open and eliminate the rev limiter and try running that. First going to start with replacing my ground wire completely. It's the original cable from 1993 but last year I did crimp on new hoop ends for the terminal bolts to go through. Going to rebuild carbs too. They're old and sucked up hella salt water last year.

 

[swannysxr]

Open up the Ebox, and look for signs of arcing near the coil. The symptoms you're describing sound like a coil, not a cdi

 

[bondra131]

Ding ding swannysxr knows his ! I changed the ground cable. Then cranked on it in my dim garage just to make sure it was grounded. And saw a blue arc popping out of my coil wire right where the wire is pushed up against my dry exhaust expansion chamber! There's the tiniest crack in the rubber insulation on that wire.. And the aluminum pipe is causing an arc to come out of it haha wow. Something so minor!

 

[bondra131]

This is why I tried to use extra cooling line material to slide over my coil wires.. But even with lube I was only able to shove half of my wires through the tube! So I ran without it. Woulda been good protection if I could have fit it all through the hose... It's an oem coil pack so the wires aren't very protected
