    Problem with a 99 gsxlimited.

    Hey, long time.. My Friend was riding his ski while back. ( 99 GSXL ) Had to jump start the ski due to dead battery. Ski ran great all day then poped the 5 am fuse. Changed out the fuse and after starting the ski for a min it repops the fuse. Took it home and attempting to flush the engine of the salt water. Notice smoke from the MPEM. I got a used MPEm and installed it. The used one I bough pops the fuse as soon as I put the Dess key in. The dess key came with it programmed to that dess. Dealer told me on on a 99 theres no way to test them. But is there any way? Anyone know the Ohm reading you should have. Any help would be great, thanks!

    Start unplugging stuff still that fuse quits blowing... Probably the trim system if I had to guess...

    Pretty sure there is a sticker right around the battery that says in bold letters: DO NOT JUMP START ENGINE WITH BATTERY CONNECTED TO THE WATERCRAFT.

    He roasted the rectifier when he jumped it, located in the MPEM. This in turn roasted the stator. The stator needs to be replaced too, located under the front cover of the engine.

    Then the used MPEM you bought will work.

    I was just wondering how you would jump start it then? someone said dont do it with the battery connected so if i disconnect it and hook it up to a buddies ski it is safe to do? just wondering for the day i have a dead battery or a buddy does.

    Yep, that is correct. I got to personally witness two guys out in the ocean pull a set of jumper cables out in the middle of the water and hook it to both batteries and start the ski back up, hahahaha. But from ski to ski yes you can.
    That 5 amp fuse maybe your trim system like red rider said. Before you start taking everything apart, try and unplug the vts system and see what happens. Its a simple test just to negate that being the culprit.
    But I believe RQ is 99% correct in the diagnosis.
