Columbia cart takes off on its on

[Caterk]

Hello, I have a 1990's Columbia par car I just bought. I got some good batteries for it and put them in and hooked them up correct but every time I touch the positive cable to the battery the cart takes off on its own. The key switch is off. Could any of you guys help me with my problem? Stuck solenoid? Key switch wired wrong? Also why does it look like I have 4 solenoids in the cart? Thanks!
