new SV730 won't crank

Hello, I have replaced a Kohler SV590 on my Toro 4200 ztr with a Kohler SV730. When I turn on the key you can hear the fuel pump click but it won't crank. I can jump the big posts of the solenoid and it will crank. When I jump from the big post of the solenoid (battery side) to the small post it does not crank. Does this indicate a bad solenoid?

Thanks,

Ravid
