Starting issues

I have a 1959 Ford Workmaster 601. I swapped the old solenoid for a new one. Wiring is exactly the same as the old. (4 posts/12Volts) But now when I turn the key it tries to start rather than like before it waited for me to push the button. I am not the most knowledgeable when it comes to mechanical work. So I thought I could ask those that are. Any help would be a huge blessing.
 
In that case your likely to have a new bad part which sadly is too common now days

The same number of posts doesn't mean that it's wired the same internally. Sounds like the primary is internally grounded to the case of the solenoid. It needs to be an isolated primary solenoid to be compatible with the neutral safety starter switch that completes the circuit to ground for the primary. If the primary is internally grounded, then the case of the solenoid completes the path to ground and it will always power the starter without needing to push the starter button.
 

Just because it has 4 posts doesn't mean it is the correct solenoid. It sounds like you got a grounded base solenoid, with a resistor bypass circuit via the I terminal. You should have an isolated base 4 terminal solenoid, where one small terminal receives power and your start button provides the ground through the other small terminal. Unhook the wires and cables from the solenoid. Check with an ohmmeter or continuity tester to see if there is continuity between the "S" terminal and the mounting base. If you do it is the wrong solenoid to use with the safety starter button.
