IF you are talking about the main power section of the starter solenoid, it works no matter which way you hook it up.
If you hooked up both leads to one side, then I say duh!
Disconnect the bat and check it with an ohm meter if you dont believe me.
Sounds like he didn't replace the the old solenoid one side at a time. Instead, took everything off the old one, then unsuccessfully put it all back on the new one.
