I was on my 1973 Ford 2000 going to load it to do a plow job and it died. Now it won't start back. Will not even turn over. I have replaced battery cables, solenoid, and ignition switch and still nothing. I put my customer off when this happened and had to put him off again due to the weather. I'm afraid he will go with someone else if I put him off again so I really need to get this tractor running back tomorrow morning. Can someone PLEASE help? I have power everywhere there needs to be power. The only thing I have checked is the coil. Would this make it stall and not start back?
