My truck turns over really fast then after about 8 rotation it just stops like the battery is dead.. also been melting battery positive cable and starter cable... burned up 3 starters. 7 soli nodes , 4 battery cables. I'm at my end on this truck... it's a 1989 f150 with 4.9 and 5 speed.. any information would help. ... also it's not ground issue. Have three grounds , one on engine, frame and body.
