John Deere L100 tractor will not crank just click!

I have a John Deere L100 mower and rescently blew the engine. I bought a direct replacement engine on-line and installed it puting everything back the way it was when I took the old one out. Now when I go to start it...nothing. Doesnt even try to crank. I thought maybe I need a new battery. Got a new battery and still nothing. Thought maybe the solenoid. Got a new solenoid but nothing. If I jump the solenoid it will crank but not stay on. The terminals on the battery are clean and I dont see any obvious problems with any wires. When I go to turn the key the carburator will click but not the solenoid. When I put the key in the on position there is current going to the carb but there is no current going to the 2 prongs on the solenoid. I read somewhere that it might be a ground and there is a wire that needs to be connected to one of the bolt that holds the engine to the frame but I don't see it.

It's probably a blown fuse. It's in the small red wire coming from the solenoid post where the battery terminal connects.

Look for disconnected safety sensors

I have the same symptoms and I followed a purple wire from the selenoid to the side where the brake pedal sensor was and it was disconnected from where it should have been. This caused the tractor not to turn crank even though the brake pedal was pressed down. I need to buy another sensor at the end since it looks like the plastic piece that holds it in place was broke.

If not that, then check your PTO and seat safety sensors are in place.

Good luck
