I'm also pretty much convinced it's the alternator also. Yesterday, it seemed to have cured itself - at least for the time being. Never noticed low voltage at all. I printed your post out and we are keeping an eye on things - hoping to make it through this season or at least 'til a rainy spell when we can take the time to look into it. I sure appreciate everyone's input! Finished soybeans yesterday. Still have a couple hundred acres of corn to do - some is ours, some is for others. Kinda hoping to pick up some more jobs this fall - when combining ends, it's time to cut wood for the winter and I don't look forward to that job at all! Thanks again!
