Positive wire from solenoid to battery get scorching hot. Why?

[Snakeyprimo]

Scooter just stalls! I have to press the ignition switch a couple of times before I can get the stator to continuously turn and the longer it does the hotter the wire will get. I just had I replace the solenoid because the old one would just click and the wire would get hot, now, same thing and I'm afraid the same thing will happen to this solenoid if I keep trying. What's going on guys?? Any suggestions? I'm seriously desperate
