John Deere 770 no power

[Loop64]

I went to start my 770 yesterday and I heated the glow plugs by turning the ignition counter clockwise for 10 seconds ( as normal) then went to start it and it turned over for a second then I lost all power ( no lights. No red lights on the dash) I checked everything as much as I can... Power to the starter and power to ignition switch (12.6 v). Any ideas.. Thanks in advance

So, the solenoid is throwing power to the starter? Ken Sweet

If your loosing power to gauges and to the starter but getting a voltage reading look for a loose ground wire. There may be several. One on the frame in the engine area, one could be under the dash and one on the engine block..

I found a ground issue on the frame. Thank you very much for the help. I can catch up on the snow plowing now!
