I have a 2020 sea doo spark 3 up trix my son said it died on him but he got it to restart. He got it back home and I tried it out a few weeks later. Started out with out any problems I put new gas in it and sea foam in it and took it out for a little bit. It died would not turn over . I had to get towed back in to the house and suspected it was a electrical issue. It was this last Labor Day and the local dealer was closed. It would not even turn over I checked the battery and it was good. I pulled the starter relay fuse and went to the local auto parts store. Told them to just find a omc or a prong system like it . 20 bucks later I plugged it in and it started right up . It’s the big black fuse in the fuse case under the seat that you pinch open on both sides . Hopefully this will be helpful to someone. It worked out good for me . You can also get them on line .
