I recently bought a 1995 seadoo gtx. I have had do some work to it but now i have a new issue. I replaced solonoid, new battery, and used oem starter. Went to the lake today everything was goin fine until about 10 minutes in. The ski died, took off the seat and the negative side of battert was melted off and i dont know why other than bad ground cable. I dont know what gauge or awg battery cables to buy. Can someone help me out?
