John Deere 4400 no power to panel

[Griff R]

Have A jd 4400. Was snow blowing this am and when i went to turn on the flashers the whole tractor stopped with no power.
The panel has no power. Battery is charged. Power is getting to the ignition key switch. All Fuses seem to be good...help!!

When you say you get power to the switch are you testing at the switch? Do you get power out of the switch?

tested the harness battery terminal to ground and got 12v. I have tried to test the switch but don't know exactly what to look for.

How would i test power out of the Switch?

 

[K5lwq]

If you can get to the back of the switch you should have power going to the switch with key off on terminal 1. With key in run position you should have power to the red wire on terminal 5. If not I would think you have a bad switch.

6 terminals labeled BAT,ACC,ELX,IGN,ST,AID,GND

Okay Bat should be hot all the time. Turn key on and see if any of the others have power.

5 is IGN. when i do a continuity test on switch from bat to ign it shows good. When i plug the switch in i Get 12v on bat(which is 1) in the off position but nothing on 5 when i turn to run? Is switch bad even though it shows continuity from 1 to 5 in the run position.... can i stick a jumper between 1 and 5 of the terminal and see if i get panel lights?

Yes you can try a jumper wire.

Nothing. BAT to ground on the frame gives me 12v but Jumping Bat to IGN or does nothing. Tried ACC too. and i do not get any panel lights at any time.
