96 seadoo sportster boat 800cc

[ddrobs]

Took the boat out for it's first run this season
Was running for about 10mins just fine then just died no power no beeps nothing
Checked all the fuses and keeps blowing the 5amp fuse for the mpem in the fuse box in the back of the boat next to the engine
Tried a 15 amp and blows those too
Anyone have this issue or know how to trouble shoot/ fix it ?
Thanks

Sounds like the charge circuit has blown the diode in the mpem.

If this is the case they can very often be repaired, do a search for mpem repair, the process is the same for the skis as the boats.

Once repaired you will need to check the charge system or it will blow again.
