    Any places that sell rebuilt 8N governors?

    The governor on my '48 8N needs an overhaul. Unfortunately this would have to include machining a bushing to repair the worn linkage arm. It's more work than I want to put into it. Does anyone know a place that sells rebuilt governors? I'm looking for a place that might offer a trade-in on my...

    Coils going bad - A coil catastrophe.

    I appreciate everybody's input and advice. I'll be incognito for awhile while I catch up on my diagnostics homework. I'll be back though to let everyone know what I found. Thanks again.

    Coils going bad - A coil catastrophe.

    There is a resistor mounted behind the battery. Its listed as a YT Part No: A8NN12250A (for older 8Ns). That's what I'm calling a ballast resistor.

    Spark plug question

    Thank you all for your advice!

    Spark plug question

    Can someone give me a definitive answer on what plugs to use in a '48 8N? It has its original 6V system, with front mount distributor. Between YouTube videos and different sources of parts, there are countless plugs offered. I'd just like a recommendation from someone with plug experience...

    Coils going bad - A coil catastrophe.

    John - thanks again for the help. I retested the coil and, sure enough, I'm getting a spark off the secondary. You helped me identify my mistake in how I was originally testing. I still have the starting problem, but at least I know its not the coil. Although the points I have are cheap new...

    Thank you, John. This helps me a lot. I'm going back to the drawing board and will retest.

    Coils going bad - A coil catastrophe.

    I'm not sure what I should be reading for the coil, but my primary resistance is 1.4 ohms, and the secondary resistance is 6.9 ohms. I determined the coil to be bad by removing the coil and distributor from the tractor, connecting 6V to the coil, jumping from the coil primary to the points...

    What could be killing coils?

    Thanks Bruce. You're right, it makes no sense to just start replacing parts. I checked the coil by connecting 6V to the input, jumping from the primary to the points, grounding the distributor to the positive on the battery, and checking if there's a spark when the points are closed and I...

    What could be killing coils?

    Help! I've traced my 8N starting problem to a bad coil. The distributor is a front mount with the original 6V system and a good battery. I've replaced the coil with a new one. The tractor started right up and ran well for a few minutes. Then it wouldn't restart. I tested and found the new coil...

    Coils going bad - A coil catastrophe.

    Thanks. The ballast resistor is only a few years old, but maybe its bad. I figured if I was getting voltage to the coil, the resistor was OK. Cheap enough to change. Yes, original 6V system, that's never given me a problem until now. Battery is good.

    Thanks Bob. Will do. And yes, original stock 6V

    Coils going bad - A coil catastrophe.

    Help! I've traced my 8N (front distributor) starting problem to a bad coil. I replaced the coil with a new one. The tractor started right up and ran well for a few minutes. Then it wouldn't restart. I tested and found the new coil to now be bad. I don't want to buy a new coil to then have it go...

    No spark has got me stumped.

    Forgot to mention - Nope, I didn't forget the cam lube. Used a small amount of white lithium cam lube.
