657 Seadoo Stator Test White to Ground Has Zero Continuity
- #2
did he try to jump start it?
that motor is known for having major trigger coil problems. did you test it? it should have 190-300 ohm resistance between the yellow/white and black/yellow wires and not grounded.

Trigger tested out fine with the ohm test. I cannot remember what the exact # was but it was near 270 from what I recall, but it fell within specs of the shop manual. I also disconnected the trigger from the 8 pin connector and tried to connect it and it still blew the fuse so I think I could eliminate that possibility.
He may have jumped it with a battery pack, but I do not think so, from what he told me the battery was low and barely started the ski, low volt light was on the entire time he was riding, turned it off and on several times throughout the time he was riding and all of a sudden, kaput when he hit a small wake, then the blown fuse problem.
Also I am not getting any gauges or instrumentation to even crank the motor, just the blown fuse.

are you sure it is the 5A fuse? and not the 15A fuse? or they did not get switched? the 5A fuse only controls the gauges, try disconnecting the red/purple, black/red two wire connector that goes to the infocenter, it's just outside the box.
jumping with a battery pack is fine but jumping with a running car with fry the MPEM.

did you check to see if the trigger coil was grounded? it should not be.

out of the machine? you removed the trigger coil? well, then check to see that the mounting bracket is an open circuit with the wires.
sure sounds like a stator/pickup problem if it blows when the mag connector is connected but normally you can find out exactly where by resistance checks.
no VTS on GTX models.

skidoo is correct with ohm readings, and even in the shop manual i just read that the stator still can be bad even if ohms out good, thats what happened to my ski, check the wires where it goes in case, mine had a shield covering them, they ground out there sometimes, but, if it doesnt blow when u un plug the stator, chances are its bad, --- diconect harness where the stator wires goes o mpem, then check all 3 charging wires (white) and see if they are grounded then, if not, the stator is grounding and blowing fuse

also check then there is a 3 white wires, check them against the black wire, should be no continuity, also against the metal part the windings are wrapped around, should have no continuity

This does say alot. I dont know for sure if its for sure a stator, but I would have a hard time believing it would blow a fuse not getting ground from the motor when you plugged in the 6pin connector (its not 8)
I am fairly sure that ebox is getting ground strictly from the stator harness. It shouldnt blow a fuse if the box has no ground.
If you need a stator let me know...I have some that are a bit dirty for $75, up to a super mint one with the good pickup bracket for $130.
And LOU....GTX not GSX....send me the rest of your :chillpill: your fired...lol

we will have to let Lou slide on this one, he is fresh off a week of Carribean margaritas and bikinis so still not thinking straight

OK yup if it blows when you have the ebox ground connected with the extra wire and the Stator wasnt plugged in....its the MPEM.
It could have been fried by a jumpstart a long time ago...burned the resistor or whatever almost all the way out, and the jarring hit made it come apart.
We had a lightening strike hit the house a few years ago and zapped out everything hooked to the phone line...except one SAT box. I opened it up and it fried the hell out of it...but it worked. And it kept working for a few months. Then one day...dead.

There is a diode in there that is quite sensitive.
You can jump with a battery as long as that machine isnt running. The jump packs are debatable.
Typically its the chargers that have the 50amp start function that wipe them out, along with hooking up the battery backwards. A fuse can only blow so fast...so damage can be done before it blows.
Trickle chargers arent an issue although I recommend a good charger. The Optimate 4 is a great investment.
I typically unhook the positive wire just as a precaution...it shouldnt do any damage, but I dont need a customer's MPEM go bad.

I have always had good luck with Interstate batteries, but I dont know if they are nationwide or not.
Whatever you buy will last a heck of a lot longer using the Optimate!
