Bad...?
Bad? Yes, but it might be able to be repaired. Go to the Buy/Sale and trade section of the forum. There is a thread made about a member who knows how to make this fix. The problem is a diode gone bad. This usually occurs from jump starting from a running vehicle......

I suggest you check out a bit further before concluding. Disconnect all wires from mpem and then one at a time reconnect each separatly. You may go thru a couple of fuses. A bad motor/module in vts or metalic particle in Stator can do that too!
In this first test you would be looking at a broken/kinked wire in the loom.

Probability or possbility?
I see that as a possibility but a huge percentage of the time, if the ski has been known to be running well, it's the mpem.
I'd have to agree with you though, it is a possibility, just not a probability. There has only been one stator in the forum since I've been here, that grounded with shavings and shorted. He found that out when he replaced a bad bearing and piston on the MAG cylinder. So, that was understandable. But, to short with no problems? I haven't seen that happen often. Can it happen? Yes... I just believe the percentage is low.
The VTS module? I've heard of that before but most seem to pop the VTS fuse too. He only mentioned that the 5 amp was blown.

This ski does not have a vts.
This is why I am leaning to the mpem. I am considering buying this ski from a young lady and It had not been run in 2 years, under 100 hrs on ski.
She stated to me that all it needed was a battery.
Lanyard was connected and fuel knob was on when I first saw it.
Stated it had not been rolled, wet, etc.
This is all I know of ski.
It is clean as a wistle and you could practically eat off the engine, parts, etc.
Clean and well taken care of.

Diode...
The 5 amp fuse is the mpem fuse. The 15 amp is from your charging circuit. I'm pretty sure your going to find you the diode is bad. See if you can ask if she ever remembers anyone trying to jump it off with a car. If the lanyard was left on it and fuel was on, it seems she may have offered it to someone before you and they tried to start it with their car.
With little knowledge on it, it'll be hard to believe it's anything else. From what I understand of this problem, if the diode is bad, it allows power to travel in both directions. Mike, with All Things Custom has been in the forum for a while. He's fixed quite a few but I haven't seen him around lately.
Good luck........:cheers:

my buddy 1998 gtx limited had same problem but sometimes the 5 amp would blow and the 15 amp but usually the 5 amp. It was metal shavings from the starter and flywheel shorting out the stator. You can check by unhooking the stator plug at the stator and replace fuse and see if it blows.... if not most likely shavings. Its a pain to do and didn't cost anything so we pulled the stator cover and blow all the shavings out and put it back together and was fine the rest of the season.
951 verses 717?
I really don't think there is any comparison to the electrical systems between these two engines. The 717 uses the CDI (Capacitor Discharge Ignition) system and the 951 uses the DC-CDI (Direct Current-Capacitor Discharge Ignition).
His comments in post #6 is what leads me to believe that someone has probably tried to start this ski by jumping it. There is no reason I can see, that would lead me to believe that metal shavings should or could be present. There just isn't enough hours on it.
You can disconntect your plug from the magneto to your rectifier, then put in a new fuse and put the lanyard back on. See if it pops the fuse. If not, see if it'll roll over and give you fire. Could be a faulty rectifier or mag. So, because of the cost of repair or replacing the MPEM, might as well check and eliminate all other possibilities.........:cheers:

Battery...?
We spoke via PM. In our exchange in conversation, the lady did say she connected the battery up to the wrong terminals.... Still doing the checks on the electrical system before replacment may be a good idea.
To replace it would cost about $410 bucks. But, you'd need to have a new lanyard programmed.......:cheers:
