I made a post before and I was not very clear on some things so I will try this again and do my best to put it in terms that can be easily understood. Here is my story, about a month ago I purchased a Ford 1200 tractor with 768 front loader. When I bought it, it wouldn't start. I put a brand new starter on it, changed the oil, bleed the fuel system, topped off the radiator with coolant and then it started right up and ran like a dream. I have used ether/starting fluid (same thing?) To get it started, even with the glow plugs it would not start after it sat overnight or long enough to get cold. So the first time starting it for the day I would spray a small amount of ether in the filter and it would start just fine. A couple of days ago I was dragging a,small log and it started to cut out and then it died, when I opened the hood, there was coolant over flowing from the radiator cap and the radiator cap was still on, possibly not sealed right, also it was out of fuel. So I bleed the fuel system added coolant and tried to start it with ether and it cranks over slowly acting as if it has low voltage and then suddenly stops with a grinding noise that sounds as if its,coming from the alternator or somewhere around that area. Absolutely wont start and I'm afraid to try too many times because of the grinding. I took some pictures and a video but I can't figure out how to upload them.I will try to post pictures and video if anyone knows how then let me know. Thanks if I left anything out then I'm sorry feel free to ask questions, Im wanting to know where do I start trouble shooting this?could this be something simple of something very bad?possible problems and solutions. I know,it sounds like I messed the motor up with ether I understand that, I want to know, how do I confirm that?trying to get a process of elimination going on, any help would be grateful, not sure if pics,uploaded or not but the last pic is,where the grinding sounds like it is coming from. This is my first diesel and first tractor,I know my way around a transmission or any gas vehichle but not familiar with diesel. ALSO, I drained out the coolant and it almost looked like rusty water.I did put a few stop leak tabs in the radiator to plug up a,small leak.
