Get nothing when I turn on the ignition switch

I have a Poulan 1338 lawn tractor. Nothing happens when I turn on the ignition switch. The lawn tractor was operating fine. I stopped it for about 5 minutes. When I tried to restart it - NOTHING. Then I replaced the ignition switch and solenoid. I disconnected the seat safety switch and reconnected the two wires with a wire nut. I have juice at the solenoid coming from the battery. When I put the key in the start position I get no juice at the three other posts on the solenoid. Just juice at the 4th post coming from the battery. What is my solution? Thank you in advance.
