John Deer 5045D

This weekend I was bush hogging my farm went and parked the tractor and shut it all off. I went back to start the tractor and when I turned the key the normal lights come on and when I tried to start it there was a click and all power was gone. I checked the battery and it is good plus it is only two weeks old. All fuses are good. I have tried to found a electrical schematic of the tractor but have not found one. Can anyone help to find the issue and send me a link for the schematic

Is pto turned off?

Are you SURE all fuses are ok?
That model is famous for a cold start advance sensor failing. When it fails it shorts and blows fuse. Follow wires from fuel pump to sensor on block. Fuse can be replaced and sensor can be unplugged for tractor to start. Replace sensor later.

Yes pto is off and all fuses check good. Also if the cold start advance sensor was bad I should still have voltage to light the dash when the key is turned. Also the fuse I have checked are the ones that are on the left side of the tractor right by the fire wall. Is there any under the dash are behind the panel that the key switch is mounted?

I would go and check your connections on your battery posts and also follow your ground wire to where it's grounded to the frame. Loose connections can sometimes work fine on low draw items like gauges but when they get the heavy draw from the starter they will break connection.

I had an old jeep that did this. Pop the hood jiggle the posts and it would fire right up. I figured it was a good anti-theft device.
