Hey Karin; You do realize that there is an entire board on this site dedicated to just the ford N-series tractors, right? Good. One of the more knowledgable but kinda grumpy types on the N-board constantly preaches "Clean, bright, and tight" on all electrical connections. This is especially important on 6V machines but is just a good for 12V machines as well. Rust and corrosion anywhere will limit how well the electricity flows on the tractor. Since you have the starter off, look at the metal on the flywheel housing that was covered up by the starter...is it rusty? if so, clean it up good with a wire brush. Do the same to the face of the starter when you get it back. This is where the starter grouds itself and it needs a good connection. Another spot is the ground cable. Especially if it is a woven strap. They are prone to rust and get corroded and not work well. Check ALL electrical connections and make sure there isn't paint build up under them that is preventing good sparkie flow. If all that checks good and the starter still won't do right (and the battery is fully charged), then you may have bad brushes in the starter meaning rebuild time. Also, if your tractor is still 6V, I found that jumping directly to the starter with modern battery cables wasn't always good enough. 12V batteries use smaller diameter cables and that is too small for 6V systems to get enough "juice" to run. I had my starter rebuilt only to find out that my battery cables were too small! Glad that you found out what your problem was, but please remember that there is a board here just for these tractors and we'd be more than happy to help you out with any problem you may run across. Good luck and enjoy your 8N! Jeb 1947 ford 2N
