Wore out, you are correct. I was more focused on clarifying what Jim said. To the OP do you have any wires connected to the starter side terminal of the solenoid that has the strap on it feeding the starter? If so those connections are incorrect. You may possibly be trying to energize the starter through to small of wiring that connects to the ignition. However other connections in your ignition circuit would have to be wrong as well for this to happen. I am envisioning that you possibly have a 3 terminal solenoid and by following a diagram you mistook the 4th wire on the solenoid to be placed on the large terminal for the starter. The if you incorrectly placed the other end of that wire for the starting step up circuit on the ignition switch side of the resistor you would have the result you explained. If you have a 3 terminal solenoid it is incorrect. You need a 4 terminal solenoid with 2 large terminals and 2 small terminals. There small terminal labeled ..S.. will be fed from the starter button. The other small terminal labeled ..I.. would connect to the step-up circuit for starting. This wire would connect to the resistor block on the coil side. I do not have access to a 450 wiring diagram but I cannot even think of a place in the wiring that would require a ground connection other than the base of the regulator. Maybe possibly the head lights.
