Help, I was running my F3 in wheat today and the electric to the cab just stopped. The voltage meter went from in the green and 12 on the meter to nothing and then everything quit. No power to any of the switches. It has been doing this all season it would do it for a second then come back on and away we could go. The batteries seem strong enough because I can start the combine and shut it off and but no power to the switches. I couldn't post on the general place so I did it here I hope someone can help Thanks John
